NUCLEAR REGULATORY COMMISSION
Biweekly Notice; Applications and Amendments to Facility
Operating Licenses Involving No Significant Hazards Considerations
I. Background
Pursuant to section 189a. (2) of the Atomic Energy Act of 1954, as
amended
[[Page 16616]]
(the Act), the U.S. Nuclear Regulatory Commission (the Commission or
NRC staff) is publishing this regular biweekly notice. The Act requires
the Commission publish notice of any amendments issued, or proposed to
be issued and grants the Commission the authority to issue and make
immediately effective any amendment to an operating license upon a
determination by the Commission that such amendment involves no
significant hazards consideration, notwithstanding the pendency before
the Commission of a request for a hearing from any person.
This biweekly notice includes all notices of amendments issued, or
proposed to be issued from March 5, 2004 through March 18, 2004. The
last biweekly notice was published on March 16, 2004 (69 FR 12361).
Notice of Consideration of Issuance of Amendments to Facility Operating
Licenses, Proposed No Significant Hazards Consideration Determination,
and Opportunity for a Hearing
The Commission has made a proposed determination that the following
amendment requests involve no significant hazards consideration. Under
the Commission's regulations in 10 CFR 50.92, this means that operation
of the facility in accordance with the proposed amendment would not (1)
involve a significant increase in the probability or consequences of an
accident previously evaluated; or (2) create the possibility of a new
or different kind of accident from any accident previously evaluated;
or (3) involve a significant reduction in a margin of safety. The basis
for this proposed determination for each amendment request is shown
below.
The Commission is seeking public comments on this proposed
determination. Any comments received within 30 days after the date of
publication of this notice will be considered in making any final
determination. Within 60 days after the date of publication of this
notice, the licensee may file a request for a hearing with respect to
issuance of the amendment to the subject facility operating license and
any person whose interest may be affected by this proceeding and who
wishes to participate as a party in the proceeding must file a written
request for a hearing and a petition for leave to intervene.
Normally, the Commission will not issue the amendment until the
expiration of 60 days after the date of publication of this notice. The
Commission may issue the license amendment before expiration of the 60-
day period provided that its final determination is that the amendment
involves no significant hazards consideration. In addition, the
Commission may issue the amendment prior to the expiration of the 30-
day comment period should circumstances change during the 30-day
comment period such that failure to act in a timely way would result,
for example in derating or shutdown of the facility. Should the
Commission take action prior to the expiration of either the comment
period or the notice period, it will publish in the Federal Register a
notice of issuance. Should the Commission make a final No Significant
Hazards Consideration Determination, any hearing will take place after
issuance. The Commission expects that the need to take this action will
occur very infrequently.
Written comments may be submitted by mail to the Chief, Rules and
Directives Branch, Division of Administrative Services, Office of
Administration, U.S. Nuclear Regulatory Commission, Washington, DC
20555-0001, and should cite the publication date and page number of
this Federal Register notice. Written comments may also be delivered to
Room 6D22, Two White Flint North, 11545 Rockville Pike, Rockville,
Maryland, from 7:30 a.m. to 4:15 p.m. Federal workdays. Copies of
written comments received may be examined at the Commission's Public
Document Room (PDR), located at One White Flint North, Public File Area
O1F21, 11555 Rockville Pike (first floor), Rockville, Maryland. The
filing of requests for a hearing and petitions for leave to intervene
is discussed below.
Within 60 days after the date of publication of this notice, the
licensee may file a request for a hearing with respect to issuance of
the amendment to the subject facility operating license and any person
whose interest may be affected by this proceeding and who wishes to
participate as a party in the proceeding must file a written request
for a hearing and a petition for leave to intervene. Requests for a
hearing and a petition for leave to intervene shall be filed in
accordance with the Commission's ``Rules of Practice for Domestic
Licensing Proceedings'' in 10 CFR Part 2. Interested persons should
consult a current copy of 10 CFR 2.309, which is available at the
Commission's PDR, located at One White Flint North, Public File Area
01F21, 11555 Rockville Pike (first floor), Rockville, Maryland.
Publicly available records will be accessible from the Agencywide
Documents Access and Management System's (ADAMS) Public Electronic
Reading Room on the Internet at the NRC Web site, http://www.nrc.gov/
reading-rm/doc-collections/cfr/. If a request for a hearing or petition
for leave to intervene is filed within 60 days, the Commission or a
presiding officer designated by the Commission or by the Chief
Administrative Judge of the Atomic Safety and Licensing Board Panel,
will rule on the request and/or petition; and the Secretary or the
Chief Administrative Judge of the Atomic Safety and Licensing Board
will issue a notice of a hearing or an appropriate order.
As required by 10 CFR 2.309, a petition for leave to intervene
shall set forth with particularity the interest of the petitioner in
the proceeding, and how that interest may be affected by the results of
the proceeding. The petition should specifically explain the reasons
why intervention should be permitted with particular reference to the
following general requirements: (1) The name, address and telephone
number of the requestor or petitioner; (2) the nature of the
requestor's/petitioner's right under the Act to be made a party to the
proceeding; (3) the nature and extent of the requestor's/petitioner's
property, financial, or other interest in the proceeding; and (4) the
possible effect of any decision or order which may be entered in the
proceeding on the requestor's/petitioner's interest. The petition must
also set forth the specific contentions which the petitioner/requestor
seeks to have litigated at the proceeding.
Each contention must consist of a specific statement of the issue
of law or fact to be raised or controverted. In addition, the
petitioner/requestor shall provide a brief explanation of the bases for
the contention and a concise statement of the alleged facts or expert
opinion which support the contention and on which the petitioner/
requestor intends to rely in proving the contention at the hearing. The
petitioner/requestor must also provide references to those specific
sources and documents of which the petitioner is aware and on which the
petitioner/requestor intends to rely to establish those facts or expert
opinion. The petition must include sufficient information to show that
a genuine dispute exists with the applicant on a material issue of law
or fact. Contentions shall be limited to matters within the scope of
the amendment under consideration. The contention must be one which, if
proven, would entitle the petitioner/requestor to relief. A petitioner/
requestor who fails to satisfy these requirements with respect to at
least one contention will not be permitted to participate as a party.
[[Page 16617]]
Those permitted to intervene become parties to the proceeding,
subject to any limitations in the order granting leave to intervene,
and have the opportunity to participate fully in the conduct of the
hearing.
If a hearing is requested, and the Commission has not made a final
determination on the issue of no significant hazards consideration, the
Commission will make a final determination on the issue of no
significant hazards consideration. The final determination will serve
to decide when the hearing is held. If the final determination is that
the amendment request involves no significant hazards consideration,
the Commission may issue the amendment and make it immediately
effective, notwithstanding the request for a hearing. Any hearing held
would take place after issuance of the amendment. If the final
determination is that the amendment request involves a significant
hazards consideration, any hearing held would take place before the
issuance of any amendment.
A request for a hearing or a petition for leave to intervene must
be filed by: (1) First class mail addressed to the Office of the
Secretary of the Commission, U.S. Nuclear Regulatory Commission,
Washington, DC 20555-0001, Attention: Rulemaking and Adjudications
Staff; (2) courier, express mail, and expedited delivery services:

Connecticut Yankee Atomic Power Company, Docket No. 50-213, Haddam Neck
Plant, Middlesex County, Connecticut
Date of amendment request: January 9, 2004.
Description of amendment requests: The Haddam Neck Plant (HNP) is
currently undergoing active decommissioning. The proposed amendment
would revise Technical Specifications (TS) 6.6.4, 6.7.1, and 6.8 in
accordance with Technical Specification Task Force (TSTF) travelers
152, 258 and 308 to reflect changes to Title 10 Part 20 of the Code of
Federal Regulations (CFR). The proposed amendment would also revise TS
6.1, 6.2.1, 6.4, 6.5, and 6.6 to reflect the use of generic
organizational titles, modeled after TSTF 65 revision 1.
Basis for proposed no significant hazards consideration
determination: As required by 10 CFR 50.91(a), the licensee has
provided its analysis of the issue of no significant hazards
consideration, which is presented below:
1. Will the proposed change involve a significant increase in
the probability or consequences of an accident previously evaluated?
No. The proposed changes are proposed to reflect the current
version of 10 CFR 20 and to eliminate the need for a TS change each
time there is a organizational change. These changes do not impact
any design basis accidents described in the updated Final Safety
Analysis Report (FSAR) for the HNP. Since the proposed changes are
administrative or editorial, they cannot affect the likelihood or
consequences of accidents.
Therefore, the proposed administrative changes to the Operating
License and Technical Specifications will not increase the
probability or consequences of an accident previously evaluated.
2. Will the proposed change create the possibility of a new or
different type of accident from any accident previously evaluated?
No. The proposed changes do not affect plant system operation.
The proposed changes do not involve a physical alteration to the
plant or any change in plant configuration. The proposed changes do
not require any new operator actions. The changes do not alter the
way any structure, system, or component functions. The changes do
not introduce any new failure modes.
Therefore, this proposed administrative change will not create
the possibility of a new or different kind of accident from any
previously evaluated.
3. Will the proposed change involve a significant reduction in a
margin of safety?
No. The proposed changes will make the HNP Operating License and
Defueled Technical Specifications consistent with the current 10 CFR
20, and eliminate the need for a TS change each time there is an
organizational change. The proposed changes will not result in any
technical changes to current requirements. The proposed changes have
no effect on assumptions and any acceptance criteria for the design
basis accidents described in the updated FSAR for the HNP.
Therefore, the proposed administrative changes will not result
in a reduction in a margin of safety.
The NRC staff has reviewed the licensee's analysis and, based on
this review, it appears that the three standards of 10 CFR 50.92(c) are
satisfied. Therefore, the NRC staff proposes to determine that the
amendment request involves no significant hazards consideration.

Entergy Operations, Inc., Docket No. 50-313, Arkansas Nuclear One, Unit
No. 1, Pope County, Arkansas
Date of amendment request: February 9, 2004.
Description of amendment request: The proposed amendment deletes
requirements from the technical specifications (TS) to maintain
hydrogen recombiners and hydrogen monitors. Licensees were generally
required to implement upgrades as described in NUREG-0737,
``Clarification of TMI [Three Mile Island] Action Plan Requirements,''
and Regulatory Guide (RG) 1.97, ``Instrumentation for Light-Water-
Cooled Nuclear Power Plants to Assess Plant and Environs Conditions
During and Following an Accident.'' Implementation of these upgrades
was an outcome of the lessons learned from the accident that occurred
at TMI Unit 2. Requirements related to combustible gas control were
imposed by Order for many facilities and were added to or
[[Page 16618]]
included in the TS for nuclear power reactors currently licensed to
operate. The revised 10 CFR 50.44, ``Standards for Combustible Gas
Control System in Light-Water-Cooled Power Reactors,'' eliminated the
requirements for hydrogen recombiners and relaxed safety
classifications and licensee commitments to certain design and
qualification criteria for hydrogen and oxygen monitors.
The NRC staff issued a notice of availability of a model no
significant hazards consideration (NSHC) determination for referencing
in license amendment applications in the Federal Register on September
25, 2003 (68 FR 55416). The licensee affirmed the applicability of the
model NSHC determination in its application dated February 9, 2004.
Basis for proposed no significant hazards consideration
determination: As required by 10 CFR 50.91(a), an analysis of the issue
of no significant hazards consideration is presented below:
Criterion 1--The Proposed Change Does Not Involve a Significant
Increase in the Probability or Consequences of an Accident Previously
Evaluated.
The revised 10 CFR 50.44 no longer defines a design-basis loss-
of-coolant accident (LOCA) hydrogen release, and eliminates
requirements for hydrogen control systems to mitigate such a
release. The installation of hydrogen recombiners and/or vent and
purge systems required by 10 CFR 50.44(b)(3) was intended to address
the limited quantity and rate of hydrogen generation that was
postulated from a design-basis LOCA. The Commission has found that
this hydrogen release is not risk-significant because the design-
basis LOCA hydrogen release does not contribute to the conditional
probability of a large release up to approximately 24 hours after
the onset of core damage. In addition, these systems were
ineffective at mitigating hydrogen releases from risk-significant
accident sequences that could threaten containment integrity.
With the elimination of the design-basis LOCA hydrogen release,
hydrogen monitors are no longer required to mitigate design-basis
accidents and, therefore, the hydrogen monitors do not meet the
definition of a safety-related component as defined in 10 CFR 50.2.
RG 1.97 Category 1, is intended for key variables that most directly
indicate the accomplishment of a safety function for design-basis
accident events. The hydrogen monitors no longer meet the definition
of Category 1 in RG 1.97. As part of the rulemaking to revise 10 CFR
50.44 the Commission found that Category 3, as defined in RG 1.97,
is an appropriate categorization for the hydrogen monitors because
the monitors are required to diagnose the course of beyond design-
basis accidents.
The regulatory requirements for the hydrogen monitors can be
relaxed without degrading the plant emergency response. The
emergency response, in this sense, refers to the methodologies used
in ascertaining the condition of the reactor core, mitigating the
consequences of an accident, assessing and projecting offsite
releases of radioactivity, and establishing protective action
recommendations (PARs) to be communicated to offsite authorities.
Classification of the hydrogen monitors as Category 3 and removal of
the hydrogen monitors from TS will not prevent an accident
management strategy through the use of the severe accident
management guidelines (SAMGs), the emergency plan (EP), the
emergency operating procedures (EOPs), and site survey monitoring
that support modification of emergency plan PARs.
Therefore, the elimination of the hydrogen recombiner
requirements and relaxation of the hydrogen monitor requirements,
including removal of these requirements from TS, does not involve a
significant increase in the probability or the consequences of any
accident previously evaluated.
Criterion 2--The Proposed Change Does Not Create the Possibility of a
New or Different Kind of Accident from any Previously Evaluated.
The elimination of the hydrogen recombiner requirements and
relaxation of the hydrogen monitor requirements, including removal
of these requirements from TS, will not result in any failure mode
not previously analyzed. The hydrogen recombiner and hydrogen
monitor equipment was intended to mitigate a design-basis hydrogen
release. The hydrogen recombiner and hydrogen monitor equipment are
not considered accident precursors, nor does their existence or
elimination have any adverse impact on the pre-accident state of the
reactor core or post accident confinement of radionuclides within
the containment building.
Therefore, this change does not create the possibility of a new
or different kind of accident from any previously evaluated.
Criterion 3--The Proposed Change Does Not Involve a Significant
Reduction in the Margin of Safety.
The elimination of the hydrogen recombiner requirements and
relaxation of the hydrogen monitor requirements, including removal
of these requirements from TS, in light of existing plant equipment,
instrumentation, procedures, and programs that provide effective
mitigation of and recovery from reactor accidents, results in a
neutral impact to the margin of safety.
The installation of hydrogen recombiners and/or vent and purge
systems required by 10 CFR 50.44(b)(3) was intended to address the
limited quantity and rate of hydrogen generation that was postulated
from a design-basis LOCA. The Commission has found that this
hydrogen release is not risk-significant because the design-basis
LOCA hydrogen release does not contribute to the conditional
probability of a large release up to approximately 24 hours after
the onset of core damage.
Category 3 hydrogen monitors are adequate to provide rapid
assessment of current reactor core conditions and the direction of
degradation while effectively responding to the event in order to
mitigate the consequences of the accident. The intent of the
requirements established as a result of the TMI Unit 2 accident can
be adequately met without reliance on safety-related hydrogen
monitors.
Therefore, this change does not involve a significant reduction
in the margin of safety. Removal of hydrogen monitoring from TS will
not result in a significant reduction in their functionality,
reliability, and availability.
Based upon the reasoning presented above and the previous
discussion of the amendment request, the requested change does not
involve a significant hazards consideration.

Entergy Gulf States, Inc., and Entergy Operations, Inc., Docket No. 50-
458, River Bend Station, Unit 1, West Feliciana Parish, Louisiana
Date of amendment request: February 3, 2004.
Description of amendment request: The proposed amendment would
revise Technical Specification 3.1.8, ``Scram Discharge Volume (SDV)
Vent and Drain Valves,'' to allow a vent or drain line with one
inoperable valve to be isolated instead of requiring the valve to be
restored to operable status within seven days.
The NRC staff issued a notice of opportunity for comment in the
Federal Register on February 24, 2003 (68 FR 8637), on possible
amendments to revise the action for one or more SDV vent or drain lines
with an inoperable valve, including a model safety evaluation and model
no significant hazards consideration (NSHC) determination, using the
consolidated line-item improvement process. The NRC staff subsequently
issued a notice of availability of the models for referencing in
license amendment applications in the Federal Register on April 15,
2003 (68 FR 18294). The licensee affirmed the applicability of the
model NSHC determination in its application dated February 3, 2004.
Basis for proposed no significant hazards consideration determination:
As required by 10 CFR 50.91(a), an analysis of the issue of no
significant hazards consideration is presented below:
Criterion 1--The Proposed Change Does Not Involve a Significant
Increase in the Probability or Consequences of an Accident Previously
Evaluated.
A change is proposed to allow the affected SDV vent and drain
line to be isolated when there are one or more SDV vent or drain
lines with one valve inoperable instead of requiring the valve to be
restored to operable status within 7 days. With one SDV vent or
drain valve inoperable in one or more lines, the isolation function
would be maintained since the redundant valve in the affected line
would perform its safety function of isolating the SDV. Following
the completion of the required action, the isolation function is
fulfilled since the associated line is isolated. The ability to vent
and drain the SDVs is maintained and controlled through
administrative controls. This requirement assures the reactor
protection system is not adversely affected by the inoperable
valves. With the safety functions of the valves being maintained,
the probability or consequences of an accident previously evaluated
are not significantly increased.
[[Page 16620]]
Criterion 2--The Proposed Change Does Not Create the Possibility of a
New or Different Kind of Accident From Any Accident Previously
Evaluated.
The proposed change does not involve a physical alteration of
the plant (no new or different type of equipment will be installed)
or a change in the methods governing normal plant operation. Thus,
this change does not create the possibility of a new or different
kind of accident from any previously evaluated.
Criterion 3--The Proposed Change Does Not Involve a Significant
Reduction in the Margin of Safety.
The proposed change ensures that the safety functions of the SDV
vent and drain valves are fulfilled. The isolation function is
maintained by redundant valves and by the required action to isolate
the affected line. The ability to vent and drain the SDVs is
maintained through administrative controls. In addition, the reactor
protection system will prevent filling of an SDV to the point that
it has insufficient volume to accept a full scram. Maintaining the
safety functions related to isolation of the SDV and insertion of
control rods ensures that the proposed change does not involve a
significant reduction in the margin of safety.
The NRC staff proposes to determine that the amendment request
involves no significant hazards consideration.

Florida Power Corporation, et al., Docket No. 50-302, Crystal River
Unit 3 Nuclear Generating Plant, Citrus County, Florida
Date of amendment request: December 9, 2003.
Description of amendment request: The amendment would allow a one-
time increase in the completion time for restoring an inoperable
emergency feedwater (EFW) system train to operable status to allow the
realignment of the diesel-driven EFW pump during power operations.
Basis for proposed no significant hazards consideration
determination: As required by 10 CFR 50.91(a), the licensee has
provided its analysis of the issue of no significant hazards
consideration, which is presented below:
1. Does not involve a significant increase in the probability or
consequences of an accident previously evaluated.
The proposed license amendment extends, on a one-time basis, the
Completion Time for restoring an inoperable Emergency Feedwater
System train to Operable status. The Emergency Feedwater System is
designed to provide cooling for components essential to the
mitigation of plant transients and accidents. The system is not an
initiator of design basis accidents. During the requested extended
time period of 14 days, the redundant Emergency Feedwater Pump (EFP)
will be available and capable of providing cooling to the Once-
Through Steam Generators (OTSGs) during emergency conditions. In
addition, a safety-grade motor driven pump (EFP-1) is available for
manual initiation and is capable of providing adequate EFW flow for
OTSG cooling during all design basis events. EFP-1 is also capable
of being supplied by the ``A'' train emergency diesel generator if
sufficient electrical loading capacity is available during a loss of
offsite power condition. Although Feedwater (FW) pump FWP-7 is non-
safety related and its motor is non-seismic, it will also be
available and capable of providing OTSG cooling during all but the
most limiting design basis events. FWP-7 also has a non-safety
diesel backup power supply in the event normal power is not
available.
A Probabilistic Safety Assessment (PSA) has been performed to
assess the risk impact of an increase in Completion Time. Although
the proposed one-time change results in an increase in Core Damage
Frequency and Large Early Release Frequency, the value of these
increases are considered as very small in the current regulatory
guidance.
Therefore, granting this LAR [License Amendment Request] does
not involve a significant increase in the probability or
consequences of an accident previously evaluated.
2. Does not create the possibility of a new or different type of
accident from any accident previously evaluated.
The proposed license amendment extends, on a one-time basis, the
Completion Time for restoring an inoperable Emergency Feedwater
System train to Operable status.
The proposed LAR will not result in changes to the design,
physical configuration of the plant or the assumptions made in the
safety analysis. Therefore, the proposed change will not create the
possibility of a new or different kind of accident from any
previously evaluated.
3. Does not involve a significant reduction in the margin of
safety.
The proposed license amendment extends, on a one-time basis, the
Completion Time for restoring an inoperable Emergency Feedwater
System train to Operable status. The proposed change will allow
online alignment of one of the Emergency Feedwater pumps to improve
its reliability, thus increasing the long-term margin of safety of
the system.
The proposed LAR will reduce the probability (and associated
risk) of a plant shutdown to repair an Emergency Feedwater pump. To
ensure defense-in-depth capabilities and the assumptions in the risk
assessment are maintained during the proposed one-time extended
Completion Time, CR-3 [Crystal River Unit 3] will continue the
performance of 10 CFR 50.65(a)(4) assessments before performing
maintenance or surveillance activities. Other compensatory actions
that may be implemented include: use of pre-job briefings and
periodic operator walkdowns to assess the status of risk sensitive
equipment in the redundant train, use of operator walkdowns to
assess and limit transient combustibles in risk significant fire
areas, and no elective maintenance to be scheduled in the switchyard
that would challenge the availability of offsite power to the ES
[engineered safeguards] buses.
As described above in Item 1, a PSA has been performed to assess
the risk impact of an increase in Completion Time. Although the
proposed one-time change results in an increase in Core Damage
Frequency and Large Early Release Frequency, the value of these
increases are considered as very small in the current regulatory
guidance.
Therefore, granting this LAR does not involve a significant
reduction in the margin of safety.
The NRC staff has reviewed the licensee's analysis and, based on
this review, it appears that the three standards of 50.92(c) are
satisfied. Therefore, the NRC staff proposes to determine that the
amendment request involves no significant hazards consideration.

Point Plant, Units 3 and 4, Miami-Dade County, Florida
Date of amendment request: March 3, 2004.
Description of amendment request: The proposed amendments would
revise Technical Specification (TS) Surveillance Requirement 4.0.5 by
updating the American Society of Mechanical Engineers (ASME) Boiler and
Pressure Vessel Code references as the source of inservice testing
requirements for ASME Code Class 1, 2, and 3 pumps and valves. The
proposed amendments replace reference to Section XI of the Code with
reference to ASME Code for Operation and Maintenance of Nuclear Power
Plants (ASME OM Code).
Basis for proposed no significant hazards consideration
determination: As required by 10 CFR 50.91(a), the licensee has
provided its analysis of the issue of no significant hazards
consideration, which is presented below:
1. Will operation of the facility in accordance with this
proposed change involve a significant increase in the probability or
consequences of an accident previously evaluated?
The proposed changes do not involve a significant increase in
the probability of an accident previously evaluated because no such
accidents are affected by the proposed changes. The amendments
application proposes to revise the Turkey Point Units 3
[[Page 16621]]
and 4 Technical Specifications Surveillance Requirement 4.0.5. The
proposed changes would revise the technical specifications to
conform to the requirements of 10 CFR 50.55a(f) regarding the
inservice testing of pumps and valves for the Fourth 10-Year
interval.
The current Turkey Point Units 3 and 4 Technical Specifications
reference the ASME Code, Section XI, requirements for the inservice
testing of ASME Code Class 1, 2, and 3 pumps and valves. The
proposed changes would reference the ASME OM Code, which is
consistent with 10 CFR Section 50.55a(f). In addition, surveillance
interval definitions for ``biennially or every 2 years'' as used in
the ASME OM Code would be added to TS surveillance requirement
4.0.5.b to ensure consistent interpretation of the terms.
2. Will operation of the facility in accordance with this
proposed change create the possibility of a new or different kind of
accident from any accident previously evaluated?
The proposed changes do not create the possibility of a new or
different kind of accident from any accident previously evaluated
because no new or different accident initiators are introduced by
these proposed changes.
3. Will operation of the facility in accordance with this
proposed change involve a significant reduction in a margin of
safety?
The proposed changes do not involve a significant reduction in a
margin of safety because there are no changes to initial conditions
contributing to accident severity or consequences. Thus, there is
not significant reduction in a margin of safety.
The NRC staff has reviewed the licensee's analysis and, based on
this review, it appears that the three standards of 50.92(c) are
satisfied. Therefore, the NRC staff proposes to determine that the

Nuclear Management Company, LLC, Docket No. 50-263, Monticello Nuclear
Generating Plant, Wright County, Minnesota
Date of amendment request: December 23, 2003.
Description of amendment request: The proposed amendment would
revise the Technical Specifications (TS) to eliminate the reactor head
cooling containment isolation function since the reactor head cooling
system has been removed from service. In addition, the TS are being
changed to correct and clarify existing requirements, make wording
enhancements, and revise an existing limiting condition for operation
for radiation monitors used to isolate reactor building ventilation and
initiate the standby gas treatment system (SGTS).
Basis for proposed no significant hazards consideration
determination: As required by 10 CFR 50.91(a), the licensee has
provided its analysis of the issue of no significant hazards
consideration, which is presented below:
1. Does the proposed amendment involve a significant increase in
the probability or consequences of an accident previously evaluated?
Response: No.
One of the proposed changes removes the Reactor Head Cooling
system primary containment isolation signal from the TS. The
existing piping will be removed and the existing process pipe
through the containment penetration will be cut and capped. This
equipment was only used for the shutdown-cooling (non-safety
related) mode of operation. This system does not support safe
shutdown of the facility. The proposed TS change does not introduce
new equipment or new equipment operating modes, nor does the
proposed change alter existing system relationships. These proposed
changes do not increase the likelihood of the malfunction of any
structure, system or component (SSC) or impact any analyzed
accident. Consequently, the probability of an accident previously
evaluated is not increased.
The other proposed change adds an allowable outage time to the
radiation monitors described in TS that initiate the SGTS and adds a
time requirement for placing inoperable channels in a tripped
condition. The proposed TS change does not introduce new equipment
or new equipment operating modes, nor does the proposed change alter
existing system relationships. The change does not affect plant
operation, design function or any analysis that verifies the
capability of a SSC to perform a design function. Further, the
proposed change does not increase the likelihood of the malfunction
of any structure, system or component (SSC) or impact any analyzed
accident. Consequently, the probability of an accident previously
evaluated is not affected.
Therefore, the proposed amendment does not involve a significant
increase in the probability or consequences of an accident
previously evaluated.
2. Does the proposed amendment create the possibility of a new
or different kind of accident from any accident previously
evaluated?
Response: No.
One of the proposed changes removes the Reactor Head Cooling
system primary containment isolation signal from the TS. The
existing piping will be removed and the existing process pipe
through the containment penetration will be cut and capped. This
equipment was only used for the shutdown-cooling (non-safety
related) mode of operation. The change does not create the
possibility of new credible failure mechanisms, or malfunctions. The
proposed change does not introduce new accident initiators.
Consequently, the changes cannot create the possibility of a new or
different kind of accident from any accident previously evaluated.
The other proposed change adds an allowable outage time to the
radiation monitors described in TS that initiate the SGTS and adds a
time requirement for placing inoperable channels in a tripped
condition. This change does not modify the design function or
operation of any SSC. Further the change does not involve physical
alterations of the plant; no new or different type of equipment will
be installed. The proposed change is not an indicator of any
accident previously evaluated. Consequently, the probability of an
accident previously evaluated is not affected.
Therefore, the proposed amendment will not create the
possibility of a new or different kind of accident from any accident
previously analyzed.
3. Does the proposed amendment involve a significant reduction
in the margin of safety?
One of the proposed changes removes the Reactor Head Cooling
system primary containment isolation signal from the TS. The
existing piping will be removed and the existing process pipe
through the containment penetration will be cut and capped. This
equipment was only used for the shutdown-cooling (non-safety
related) mode of operation. This system does not support safe
shutdown of the facility. This change does not exceed or alter a
design basis or a safety limit for a parameter established in the
MNGP [Monticello Nuclear Generating Plant] Updated Safety Analysis
Report (USAR) or the MNGP facility license. Consequently, the change
does not result in a significant reduction in the margin of safety.
The other proposed change adds an allowable outage time to the
radiation monitors described in TS that initiate the SGTS and adds a
time requirement for placing inoperable channels in a tripped
condition. This change ensures continued compliance with regulatory
and licensing requirements. The change does not exceed or alter a
design basis or safety limit for a parameter established in the MNGP
USAR or MNGP facility license. Consequently, the proposed amendment
does not involve a significant reduction in the margin of safety.
Therefore, the proposed amendment does not involve a significant
reduction in the margin of safety.
The NRC staff has reviewed the licensee's analysis and, based on
this review, it appears that the three standards of 10 CFR 50.92(c) are
satisfied. Therefore, the NRC staff proposes to determine that the

Pacific Gas and Electric Company, Docket Nos. 50-275 and 50-323, Diablo
Canyon Nuclear Power Plant, Unit Nos. 1 and 2, San Luis Obispo County,
California
Date of amendment requests: February 13, 2004.
Description of amendment requests: The amendment would revise
Technical Specifications (TSs) 3.3.1, ``Reactor Trip System (RTS)
Instrumentation,'' 3.3.2, ``Engineered Safety Feature Actuation System
(ESFAS) Instrumentation,'' and 3.3.6, ``Containment Ventilation
Isolation Instrumentation.'' The purpose of the amendment is to adopt
the completion time, test bypass time, and surveillance frequency time
changes approved by the NRC in Topical Reports WCAP-14333-P-A,
``Probabilistic Risk Analysis of the RPS [reactor protection system]
and ESFAS Test Times and Completion Times,'' and WCAP-15376-P-A,
``Risk-Informed Assessment of the RTS and ESFAS Surveillance Test
Intervals and Reactor Trip Breaker Test and Completion Times.'' The
proposed changes would revise the required actions for certain action
conditions; increase the completion times for several required actions
(including some notes); delete notes in certain required actions;
increase frequency time intervals (including certain notes) in several
surveillance requirements (SRs); add an action condition and required
actions; add or revise notes in certain SRs; and revise Table 3.3.1-1.
There are also administrative corrections to the format of the TSs
(e.g., remove the bold appearance of page number 3.3-45).
Basis for proposed no significant hazards consideration
determination: As required by 10 CFR 50.91(a), the licensee has
provided its analysis of the issue of no significant hazards
consideration, which is presented below:
1. The proposed change does not involve a significant increase
in the probability or consequences of an accident previously
evaluated.
Overall protection system performance will remain within the
bounds of the previously performed accident analyses since no
hardware changes are proposed. The same RTS and ESFAS
instrumentation will continue to be used. The protection systems
will continue to function in a manner consistent with the plant
design basis. These changes to the TS [in the amendment] do not
result in a condition where the design, material, and construction
standards that were applicable prior to the change are altered.
The proposed changes will not modify any system interface. The
proposed changes will not affect the probability of any event
initiators [because the proposed changes are not event initiators].
There will be no degradation in the performance of or an increase in
the number of challenges imposed on safety-related equipment assumed
to function during an accident situation. There will be no change to
normal plant operating parameters or accident mitigation
performance. The proposed changes will not alter any assumptions or
change any mitigation actions in the radiological consequence
evaluations in the Updated Final Safety Analysis Report [for Diablo
Canyon Units 1 and 2].
The determination that the results of the proposed changes are
acceptable [to be considered for plant-specific TS] was established
in the NRC Safety Evaluations prepared for WCAP-14333-P-A, Revision
1, (issued by letter dated July 15, 1998) and for WCAP-15376-P-A,
Revision 1, (issued by letter dated December 20, 2002).
Implementation of the proposed changes will result in an
insignificant risk impact. Applicability of these conclusions has
been verified through plant-specific reviews and implementation of
the generic analysis results in accordance with the respective NRC
Safety Evaluation conditions [for the two WCAPs].
The proposed changes to the CTs [completion times], test bypass
times, and Surveillance Frequencies reduce the potential for
inadvertent reactor trips and spurious engineered safety features
actuations, and therefore do not increase the probability of any
accident previously evaluated. The proposed changes do not change
the response of the plant to any accidents and have an insignificant
impact on the reliability of the RTS and ESFAS signals. The RTS and
ESFAS will remain highly reliable and the proposed changes will not
result in a significant increase in the risk of plant operation.
This is demonstrated by showing that the impact on plant safety as
measured by the increase in core damage frequency (CDF) is less than
1.0E-06 per year and the increase in large early release frequency
(LERF) is less than 1.0E-07 per year. In addition, for the CT
changes, the incremental conditional core damage probabilities
(ICCDP) and incremental conditional large early release
probabilities (ICLERP) are less than 5.0E-07 and 5.0E-08,
respectively. These changes meet the acceptance criteria in
Regulatory Guides (RGs) 1.174 and 1.177. Therefore, since the RTS
and ESFAS will continue to perform their [safety] functions with
high reliability as originally assumed, and the increase in risk as
measured by [Delta]CDF, [Delta]LERF, ICCDP, ICLERP risk metrics is
within the acceptance criteria of existing [NRC] regulatory
guidance, there will not be a significant increase in the
consequences of any accidents.
The proposed changes do not adversely affect accident initiators
or precursors nor alter the design assumptions, conditions, or
configuration of the facility or the manner in which the plant is
operated and maintained. The proposed changes do not alter or
prevent the ability of structures, systems, and components from
performing their intended [safety] function to mitigate the
consequences of an initiating event within the assumed acceptance
limits. The proposed changes do not affect the source term,
containment isolation, or radiological release assumptions used in
evaluating the radiological consequences of any accident previously
evaluated. The proposed changes are consistent with safety analysis
assumptions and resultant consequences.
Therefore, [the] change[s do] not increase the probability or
consequences of any accident previously evaluated.
2.The proposed change does not create the possibility of a new
or different kind of accident from any accident previously
evaluated.
There are no hardware changes nor are there any changes in the
method by which any safety-related plant system performs its safety
function. The proposed changes will not affect the normal method of
plant operation. No performance requirements will be affected or
eliminated. The proposed changes will not result in physical
alteration to any plant system nor will there be any change in the
method by which any safety-related plant system performs its safety
function. There will be no setpoint changes or changes to accident
analysis assumptions.
No new accident scenarios, transient precursors, failure
mechanisms, or limiting single failures are introduced as a result
of these changes. There will be no adverse effect or challenges
imposed on any safety-related system as a result of these changes.
Therefore, the proposed changes do not create the possibility of
a new or different kind of accident from any previously evaluated.
3. The proposed change does not involve a significant reduction
in a margin of safety.
The proposed changes do not affect the acceptance criteria for
any analyzed event nor is there a change to any Safety Analysis
Limit. There will be no effect on the manner in which safety limits,
limiting safety system settings, or limiting conditions for
operation are determined nor will there be any effect on those plant
systems necessary to assure the accomplishment of protection
functions. There will be no impact on the overpower limit, departure
from nucleate boiling limits, local power peaking factor
(FQ), hot channel factor (F[Delta]H), loss-of-coolant
accident (LOCA) peak cladding temperature, peak local power density,
or any other margin of safety. The radiological dose consequence
acceptance criteria listed in the [NRC] Standard Review Plan will
continue to be met.
Redundant RTS and ESFAS trains are maintained, and diversity
with regard [to] the signals that provide reactor trip and
engineered safety features actuation is also maintained. All signals
credited as primary or secondary, and all operator actions credited
in the accident analyses will remain the same. The proposed changes
will not result in plant operation in a configuration outside the
design basis. The calculated impact on risk is insignificant and
meets the acceptance criteria contained in RGs 1.174 and 1.177.
Although there was no attempt to quantify any positive human factors
benefit due to increased CTs and bypass test times, it is expected
that there would be a net benefit due to a reduced potential for
[[Page 16623]]
spurious reactor trips and actuations associated with testing.
Implementation of the proposed changes is expected to result in
an overall improvement in safety, as follows:
(a) Reduced testing will result in fewer inadvertent reactor
trips, less frequent actuation of ESFAS components, less frequent
distraction of operations personnel without significantly affecting
RTS and ESFAS reliability.
(b) Improvements in the effectiveness of the operating staff in
monitoring and controlling plant operation will be realized. This is
due to less frequent distraction of the operators and shift
supervisor to attend to instrumentation Required Actions with short
CTs.
(c) Longer repair times associated with increased CTs will lead
to higher quality repairs and improved reliability.
(d) The CT extensions for the reactor trip breakers will provide
additional time to complete test and maintenance activities while at
power, potentially reducing the number of forced outages related to
compliance with reactor trip breaker CT, and provide consistency
with the CT for the logic trains.
Therefore, the proposed changes do not involve a significant
reduction in the margin of safety.
The NRC staff has reviewed the licensee's analysis and, based on
this review, it appears that the three standards of 10 CFR 50.92(c) are
satisfied. Therefore, the NRC staff proposes to determine that the
amendment requests involve no significant hazards consideration.

Southern California Edison Company, et al., Docket No. 50-206, San
Onofre Nuclear Generating Station, Unit 1, San Diego County, California
Date of amendment request: January 28, 2004.
Description of amendment request: Southern California Edison (SCE)
permanently shutdown San Onofre Nuclear Generating Station (SONGS),
Unit 1, in November 1992. Active decommissioning of SONGS Unit 1 began
in June 1999. As part of decommissioning, SCE constructed an
Independent Spent Fuel Storage Installation (ISFSI) at SONGS for dry
cask storage of spent fuel. In March 2004, SCE plans to begin moving
the spent fuel located in the Unit 1 spent fuel pool into the ISFSI.
SCE has proposed to eliminate License information and technical
specifications which will no longer be applicable following the
transfer of the last fuel assembly from the Unit 1 spent fuel pool to
the ISFSI.
Basis for proposed no significant hazards consideration
determination: As required by 10 CFR 50.91(a), the licensee has
provided its analysis of the issue of no significant hazards
consideration, which is presented below:
1. Involve a significant increase in the probability or
consequences of an accident previously evaluated?
No. This proposed change provides the necessary requirements for
Unit 1 with no spent fuel located in the spent fuel pool. With no
spent fuel located at Unit 1, the probability and consequence of the
fuel handling accident are removed.
Therefore, the proposed changes do not involve a significant
increase in the probability or consequences of an accident
previously evaluated.
2. Create the possibility of a new or different type of accident
from any accident previously evaluated?
No. These changes provide the necessary requirements for SONGS
Unit 1 with no spent fuel in the spent fuel pool. With no spent fuel
located at Unit 1, there is no possibility of a new or different
kind of accident.
Therefore, the proposed changes do not create the possibility of
a new or different kind of accident from any previously evaluated.
3. Involve a significant reduction in a margin of safety?
No. These changes provide the necessary requirements for SONGS
Unit 1 with no spent fuel in the spent fuel pool. With no spent fuel
located at Unit 1, the fuel handling accident is not applicable and
there is impact on the margin of safety.
Therefore, the proposed changes do not involve a significant
reduction in a margin of safety.

Date of amendment request: September 19, 2003.
Description of amendment request: The proposed change will revise
the Technical Specifications (TSs) Surveillance Requirement (SR)
4.2.4.2, to reflect the use of the Power Distribution Monitoring System
(PDMS) for a core power distribution measurement. This change will also
result in revising the Bases for 3/4.2.4 to reflect the use of the
PDMS.
Basis for proposed no significant hazards consideration
determination: As required by 10 CFR 50.91(a), the licensee has
provided its analysis of the issue of no significant hazards
consideration, which is presented below:
1. Does the proposed change involve a significant increase in
the probability or consequences of an accident previously evaluated?
No. The proposed change to TS 4.2.4.2 clarifies the use of the
PDMS as means of measuring core power distribution with one Power
Range Channel inoperable to determine if QPTR [Quadrant Power Tilt
Ratio] is within the limit. The use of PDMS was approved in
Amendment 142 and added as TS 3.3.3.11. This clarification of its
use in TS 4.2.4.2 specifies an additional method of performing the
surveillance requirement and will not increase the probability of an
accident previously evaluated.
The probability or consequences of accidents previously
evaluated in the VCSNS FSAR [Final Safety Analysis Report] are
unaffected by this proposed change because there is no change to any
equipment response or accident mitigation scenario. There are no
additional challenges to fission product barrier integrity.
Therefore, the proposed change does not involve a significant
increase in the probability or consequences of an accident
previously evaluated.
2. Does the proposed change create the possibility of a new
different kind of accident from any previously evaluated?
No. The proposed change to TS 4.2.4.2 clarifies the use of the
PDMS as means of measuring core power distribution with one Power
Range Channel inoperable to determine if QPTR is within the limit.
The use of the PDMS was approved in Amendment 142 and added as TS
3.3.3.11. This clarification of its use in TS 4.2.4.2 specifies an
additional method of performing the surveillance requirement and
does not create the possibility of a new different kind of accident
or malfunction.
No new accident scenarios, failure mechanisms, or limiting
single failures are introduced as a result of the proposed change.
The proposed change does not challenge the performance or integrity
of any safety-related system. Therefore, the proposed change does
not create the possibility of a new or different kind of accident
from any previously evaluated.
3. Does this change involve a significant reduction in margin of
safety?
No. The margin of safety associated with the acceptance criteria
of any accident is unchanged. The proposed change will have no
affect on the availability, operability, or performance of the
safety-related systems and components. A change to the surveillance
requirement is proposed; however, this clarification of the use of
PDMS in TS 4.2.4.2 specifies an additional method of performing the
surveillance requirement.

Tennessee Valley Authority, Docket No. 50-390, Watts Bar Nuclear Plant,
Unit 1, Rhea County, Tennessee
Date of amendment request: March 10, 2004.
Description of amendment request: The proposed amendment would
revise the Technical Specification allowable value for the spent fuel
pool area radiation monitors.
Basis for proposed no significant hazards consideration
determination: As required by 10 CFR 50.91(a), the licensee has
provided its analysis of the issue of no significant hazards
consideration, which is presented below:
1. Does the proposed change involve a significant increase in
the probability or consequences of an accident previously evaluated?
No. The proposed technical specification (TS) change to reduce
the allowable value for the spent fuel pool area radiation monitors
does not change any operator actions nor does it change plant
systems or structures. Therefore, the proposed change does not
result in a significant increase in the probability of a Fuel
Handling Accident (FHA). The surveillance requirement radiation
limit for the spent fuel pool area radiation monitors will be
lowered to compensate for the change in source terms which resulted
from the methodology change due to discovery of a modeling error.
This change ensures the monitors perform their safety function of
limiting the site boundary dose to a small fraction of the 10 CFR
part 100 limits. Therefore, the proposed change does not involve a
significant increase in the probability or consequences of an
accident previously evaluated.
2. Does the proposed change create the possibility of a new or
different kind of accident from any accident previously evaluated?
No. The proposed TS change does not alter the function of the
spent fuel monitors which is to initiate ABGTS [Auxiliary Building
Gas Treatment System actuation] upon an FHA. The TS allowable value
and the associated setpoints for the spent fuel pool area radiation
monitors will be lowered due to calculation methodology changes
resulting from discovery of a modeling error. The change will not
result in the installation of any new equipment or system. No new
operations procedures, conditions, or modes will be created by this
proposed change. Therefore, the proposed change does not create the
possibility of a new or different kind of accident from any
previously evaluated.
3. Does the proposed change involve a significant reduction in
margin of safety?
No. The method for calculating the radiological consequences are
revised for calculating the safety limit of the spent fuel pool area
radiation monitors to correctly account for isotopic release
fractions. The monitors' setpoints are based on 30 rem thyroid at
the site boundary resulting from an unfiltered release. At the
monitor setpoint, the monitors initiate ABGTS and thus the release
is filtered. The radiological dose consequences do not change and
remain less than a small fraction of the dose limit identified in 10
CFR 100. The surveillance requirement is being reduced for
consistency with calculation methodology changes and to ensure the
monitors perform their intended design function of limiting the site
boundary dose to less than 30 rem thyroid subsequent to an FHA.
Therefore, the proposed change does not involve a significant
reduction in a margin of safety.
The NRC staff has reviewed the licensee's analysis and, based on
this review, it appears that the three standards of 10 CFR 50.92(c) are

manner that the probability of an accident is increased. The
proposed changes will not alter assumptions relative to the
mitigation of an accident or transient event.
2. Does the proposed license amendment create the possibility of
a new or different kind of accident from any accident previously
evaluated?
The proposed changes do not involve a physical alteration of the
plant (no new or different type of equipment will be installed) or
changes in the methods governing normal plant operation. Therefore,
the proposed changes do not create the possibility of a new or
different kind of accident from any accident previously evaluated.
3. Does the proposed amendment involve a significant reduction
in a margin of safety?
The proposed changes do not alter the boron concentrations in
the safety injection accumulators, RWST [refueling water storage
tank], and casing cooling tank. The proposed changes to TS
Surveillance Requirements 3.5.1.4, 3.5.4.3, and 3.6.7.3 are
considered administrative in nature. Therefore, the proposed changes
do not involve a significant reduction in the margin of safety.
The NRC staff has reviewed the licensee's analysis and, based on
this review, it appears that the three standards of 50.92(c) are
satisfied. Therefore, the NRC staff proposes to determine that the
amendment request involves no significant hazards consideration.
