NUCLEAR REGULATORY COMMISSION
[Docket Nos. 50-206, 50-361, 50-362, and 72-41; NRC-2015-0093]
Southern California Edison Company; San Onofre Nuclear Generating
Station, Units 1, 2, and 3, and Independent Spent Fuel Storage
Installation
AGENCY: Nuclear Regulatory Commission.
ACTION: Exemption; issuance.
-----------------------------------------------------------------------
SUMMARY: The U.S. Nuclear Regulatory Commission (NRC) is granting
exemptions in response to a request from Southern California Edison
Company (SCE or the licensee) regarding certain emergency planning (EP)
requirements. The exemptions will eliminate the requirements to
maintain formal offsite radiological emergency plans and reduce the
scope of the onsite EP activities at the San Onofre Nuclear Generating
Station (SONGS), Units 1, 2, and 3, and the Independent Spent Fuel
Storage Installation (ISFSI), based on the reduced risks of accidents
that could result in an offsite radiological release at the
decommissioning nuclear power reactors. Provisions would still exist
for offsite agencies to take protective actions, using a comprehensive
emergency management plan to protect public health and safety, if
protective actions were needed in the event of a very unlikely accident
that could challenge the safe storage of spent fuel.

SUPPLEMENTARY INFORMATION:
I. Background
The SONGS Units 1, 2, and 3, are decommissioning power reactors
located in San Diego County, California. The licensee, SCE, is the
holder of SONGS Facility Operating License Nos. DPR-13, NPF-10, and
NPF-15. The licenses provide, among other things, that the facility is
subject to all rules, regulations, and orders of the NRC now or
hereafter in effect.
SONGS Unit 1 was permanently shut down in 1993. On June 12, 2013
(ADAMS Accession No. ML131640201), the licensee provided the
certifications that SONGS Units 2 and 3, had permanently ceased power
operations. On June 28 (ADAMS Accession No. ML13183A391), and July 22,
2013 (ADAMS Accession No. ML13204A304), the licensee provided
certifications that all fuel had been permanently removed from the
SONGS Units 3 and 2, reactors, respectively. As a permanently shutdown
and defueled facility, and pursuant to section 50.82(a)(2) of Title 10
of the Code of Federal Regulations (10 CFR), SCE is no longer
authorized to operate the reactors or emplace fuel into the reactor
vessels, but is still authorized to possess and store irradiated
nuclear fuel. Irradiated fuel is currently stored onsite at SONGS in
spent fuel pools (SFPs) and in the ISFSI dry casks.
During normal power reactor operations, the forced flow of water
through the reactor coolant system (RCS) removes heat generated by the
reactor. The RCS, operating at high temperatures and pressures,
transfers this heat through the steam generator tubes converting non-
radioactive feedwater to steam, which then flows to the main turbine
generator to produce electricity. Many of the accident scenarios
postulated in the updated safety analysis reports (USARs) for operating
power reactors involve failures or malfunctions of systems that could
affect the fuel in the reactor core, which in the most severe
postulated accidents, would involve the release of some fission
products into the environment. With the permanent cessation of reactor
operations at SONGS and the permanent removal of the fuel from the
reactor vessels, such accidents are no longer possible. The reactors,
RCS, and supporting systems are no longer in operation and have no
function related to the storage of the irradiated fuel. Therefore,
postulated accidents involving failure or malfunction of the reactors,
RCS, or supporting systems are no longer applicable.
The EP requirements of 10 CFR 50.47, ``Emergency plans,'' and
appendix E to 10 CFR part 50, ``Emergency Planning and Preparedness for
Production and Utilization Facilities,'' continue to apply to nuclear
power reactors that have permanently ceased operation and have removed
all fuel from the reactor vessel. There are no explicit regulatory
provisions distinguishing EP requirements for a power reactor that is
permanently shut down and defueled from those for a reactor that is
authorized to operate. To reduce or eliminate EP requirements that are
no longer necessary due to the decommissioning status of the facility,
SCE must obtain exemptions from those EP regulations. Only then can SCE
modify the SONGS emergency plan to reflect the reduced risk associated
with the permanently shutdown and defueled condition of SONGS .
II. Request/Action
By letter dated March 31, 2014 (ADAMS Accession No. ML14092A332),
``Emergency Planning Exemption Request,'' SCE requested exemptions from
certain EP requirements of 10 CFR part 50 for SONGS. More specifically,
SCE requested exemptions from certain planning standards in 10 CFR
50.47(b) regarding onsite and offsite radiological emergency plans for
nuclear power reactors; from certain requirements in 10 CFR 50.47(c)(2)
that require establishment of plume exposure and ingestion pathway
emergency planning zones for nuclear power reactors; and from certain
requirements in 10 CFR part 50, appendix E, Section IV, which
establishes the elements that make up the content of emergency plans.
In letters dated September 9, October 2, October 7, October 27,
November 3, and December 15, 2014 (ADAMS Accession Nos. ML14258A003,
ML14280A265, ML14287A228, ML14303A257, ML14309A195, and ML14351A078,
respectively), SCE provided responses to the NRC staff's requests for
additional information (RAI) concerning the proposed exemptions. In
addition, SCE submitted a letter dated October 6, 2014, which contains
security-related information, and is therefore withheld from public
disclosure. The December 15, 2014, letter is a redacted, publicly-
available version of this letter.
The information provided by SCE included justifications for each
exemption requested. The exemptions requested by SCE would eliminate
the requirements to maintain formal offsite radiological emergency
plans, reviewed by the Federal Emergency Management Agency (FEMA) under
the requirements of 44 CFR part 350, and reduce the scope of onsite EP
activities. The SCE stated that application of all of the standards and
requirements in 10 CFR 50.47(b), 10 CFR 50.47(c), and 10 CFR part 50,
appendix E is not needed for adequate emergency response capability,
based on the substantially lower onsite and offsite radiological
consequences of accidents still possible at the permanently shutdown
and defueled facility as compared to an operating facility. If offsite
protective actions were needed for a very unlikely accident that could
challenge the safe storage of spent fuel at SONGS, provisions exist for
offsite agencies to take protective actions using a comprehensive
emergency management plan (CEMP) under the National Preparedness System
to protect the health and safety of the public. A CEMP in this context,
also referred to as an emergency operations plan (EOP), is addressed in
FEMA's Comprehensive Preparedness Guide 101, ``Developing and
Maintaining Emergency Operations Plans.'' Comprehensive Preparedness
Guide 101 is the foundation for State, territorial, Tribal, and local
EP in the United States. It promotes a common understanding of the
fundamentals of
[[Page 33560]]
risk-informed planning and decision-making and helps planners at all
levels of government in their efforts to develop and maintain viable,
all-hazards, all-threats emergency plans. An EOP is flexible enough for
use in all emergencies. It describes how people and property will be
protected; details who is responsible for carrying out specific
actions; identifies the personnel, equipment, facilities, supplies and
other resources available; and outlines how all actions will be
coordinated. A CEMP is often referred to as a synonym for ``all-hazards
planning.''
III. Discussion
In accordance with 10 CFR 50.12, ``Specific exemptions,'' the
Commission may, upon application by any interested person or upon its
own initiative, grant exemptions from the requirements of 10 CFR part
50 when: (1) The exemptions are authorized by law, will not present an
undue risk to public health or safety, and are consistent with the
common defense and security; and (2) any of the special circumstances
listed in 10 CFR 50.12(a)(2) are present. These special circumstances
include, among other things, that the application of the regulation in
the particular circumstances would not serve the underlying purpose of
the rule or is not necessary to achieve the underlying purpose of the
rule.
As noted previously, the current EP regulations contained in 10 CFR
50.47(b) and appendix E to 10 CFR part 50 apply to both operating and
shutdown power reactors. The NRC has consistently acknowledged that the
risk of an offsite radiological release at a power reactor that has
permanently ceased operations and removed fuel from the reactor vessel
is significantly lower, and the types of possible accidents are
significantly fewer, than at an operating power reactor. However,
current EP regulations do not recognize that once a power reactor
permanently ceases operation, the risk of a large radiological release
from a credible emergency accident scenario is reduced. The reduced
risk is largely the result of the low frequency of credible events that
could challenge the SFP structure, and the reduced decay heat and
reduced short-lived radionuclide inventory due to decay. The NRC's
NUREG/CR-6451, ``A Safety and Regulatory Assessment of Generic BWR and
PWR Permanently Shutdown Nuclear Power Plants,'' dated August 31, 1997
(ADAMS Accession No. ML082260098) and NUREG-1738, ``Technical Study of
Spent Fuel Pool Accident Risk at Decommissioning Nuclear Power
Plants,'' dated February 28, 2001 (ADAMS Accession No. ML010430066),
confirmed that for permanently shutdown and defueled power reactors
bounded by the assumptions and conditions in the reports, the risk of
offsite radiological release is significantly less than that for an
operating power reactor.
In the past, EP exemptions similar to those requested by SCE, have
been granted to licensees of permanently shutdown and defueled power
reactors. However, the exemptions did not relieve the licensees of all
EP requirements. Rather, the exemptions allowed the licensees to modify
their emergency plans commensurate with the credible site-specific
risks that were consistent with a permanently shutdown and defueled
status. Specifically, for previous permanently shutdown and defueled
power reactors, the basis for the NRC staff's approval of the
exemptions from certain EP requirements was based on the licensee's
demonstration that: (1) The radiological consequences of design-basis
accidents would not exceed the limits of the U.S. Environmental
Protection Agency's (EPA) Protective Action Guidelines (PAGs) at the
exclusion area boundary, and (2) in the unlikely event of a beyond-
design-basis accident resulting in a loss of all modes of heat transfer
from the fuel stored in the SFP, there is sufficient time to initiate
appropriate mitigating actions, and if needed, for offsite authorities
to implement offsite protective actions using a CEMP approach to
protect the health and safety of the public. Based on precedent
exemptions, the site-specific analysis should show that there is
sufficient time following a loss of SFP coolant inventory until the
onset of fuel damage to implement onsite mitigation of the loss of SFP
coolant inventory and if necessary, to implement offsite protective
actions. To meet this criterion, the staff accepted in precedent
exemptions that the time should exceed 10 hours from the loss of
coolant until the fuel temperature reaches 900 degrees Celsius
([deg]C), assuming no air cooling.
The NRC staff reviewed the licensee's justification for the
requested exemptions against the criteria in 10 CFR 50.12(a) and
determined, as described below, that the criteria in 10 CFR 50.12(a)
are met, and that the exemptions should be granted. An assessment of
the SCE EP exemptions is described in SECY-14-0144, ``Request by
Southern California Edison for Exemptions from Certain Emergency
Planning,'' dated December 17, 2014 (ADAMS Accession No. ML14251A554).
The Commission approved the NRC staff's recommendation to grant the
exemptions in the staff requirements memorandum to SECY-14-0144, dated
March 2, 2015 (ADAMS Accession No. ML15061A521). Descriptions of the
specific exemptions requested by SCE and the NRC staff's basis for
granting each exemption are provided in SECY-14-0144 and summarized in
a table at the end of this document. The staff's detailed review and
technical basis for the approval of the specific EP exemptions,
requested by SCE, are provided in the NRC staff's safety evaluation
dated June 4, 2015 (ADAMS Accession No. ML15082A204).
A. Authorized by Law
The licensee has proposed exemptions from certain EP requirements
in 10 CFR 50.47(b), 10 CFR 50.47(c)(2), and 10 CFR part 50, appendix E,
Section IV, which would allow SCE to revise the SONGS Emergency Plan to
reflect the permanently shutdown and defueled condition of the station.
As stated above, in accordance with 10 CFR 50.12, the Commission may,
upon application by any interested person or upon its own initiative,
grant exemptions from the requirements of 10 CFR part 50. The NRC staff
has determined that granting of the licensee's proposed exemptions will
not result in a violation of the Atomic Energy Act of 1954, as amended,
or the NRC's regulations. Therefore, the exemptions are authorized by
law.
B. No Undue Risk to Public Health and Safety
As stated previously, SCE provided analyses that show the
radiological consequences of design-basis accidents will not exceed the
limits of the EPA PAGs at the exclusion area boundary. Therefore,
formal offsite radiological emergency plans required under 10 CFR part
50 are no longer needed for protection of the public beyond the
exclusion area boundary, based on the radiological consequences of
design-basis accidents still possible at SONGS.
Although very unlikely, there is one postulated beyond-design-basis
accident that might result in significant offsite radiological
releases. However, NUREG-1738 confirms that the risk of beyond-design-
basis accidents is greatly reduced at permanently shutdown and defueled
reactors. The NRC staff's analyses in NUREG-1738 concludes that the
event sequences important to risk at permanently shutdown and defueled
power reactors are limited to large earthquakes and cask drop events.
For EP assessments, this is an important difference relative to
operating power reactors, where typically a large number
[[Page 33561]]
of different sequences make significant contributions to risk. Per
NUREG-1738, relaxation of offsite EP requirements, under 10 CFR part
50, a few months after shutdown resulted in only a small change in
risk. The report further concludes that the change in risk due to
relaxation of offsite EP requirements is small because the overall risk
is low, and because even under current EP requirements for operating
power reactors, EP was judged to have marginal impact on evacuation
effectiveness in the severe earthquakes that dominate SFP risk. All
other sequences including cask drops (for which offsite radiological
emergency plans are expected to be more effective) are too low in
likelihood to have a significant impact on risk.
Therefore, granting exemptions to eliminate the requirements of 10
CFR part 50 to maintain offsite radiological emergency plans and to
reduce the scope of onsite EP activities will not present an undue risk
to the public health and safety.
C. Consistent With the Common Defense and Security
The requested exemptions by SCE only involve EP requirements under
10 CFR part 50 and will allow SCE to revise the SONGS Emergency Plan to
reflect the permanently shutdown and defueled condition of the
facility. Physical security measures at SONGS are not affected by the
requested EP exemptions. The discontinuation of formal offsite
radiological emergency plans and the reduction in scope of the onsite
EP activities at SONGS will not adversely affect SCE's ability to
physically secure the site or protect special nuclear material.
Therefore, the proposed exemptions are consistent with the common
defense and security.
D. Special Circumstances
Special circumstances, in accordance with 10 CFR 50.12(a)(2)(ii),
are present whenever application of the regulation in the particular
circumstances is not necessary to achieve the underlying purpose of the
rule. The underlying purposes of 10 CFR 50.47(b), 10 CFR 50.47(c)(2),
and 10 CFR part 50, appendix E, Section IV, are to provide reasonable
assurance that adequate protective measures can and will be taken in
the event of a radiological emergency, to establish plume exposure and
ingestion pathway emergency planning zones for nuclear power plants,
and to ensure that licensees maintain effective offsite and onsite
radiological emergency plans. The standards and requirements in these
regulations were developed by considering the risks associated with
operation of a power reactor at its licensed full-power level. These
risks include the potential for a reactor accident with offsite
radiological dose consequences.
As discussed previously in Section III of this document, because
SONGS Units 1, 2, and 3 are permanently shutdown and defueled, there is
no longer a risk of offsite radiological release from a design-basis
accident and the risk of a significant offsite radiological release
from a beyond-design-basis accident is greatly reduced when compared to
the risk at an operating power reactor. In a letter dated March 31,
2014 (ADAMS Accession No. ML14092A332), the licensee provided analyses
to demonstrate that the radiological consequences of design-basis
accidents at SONGS will not exceed the limits of the EPA PAGs at the
exclusion area boundary. The NRC staff has confirmed the reduced risks
at SONGS by comparing the generic risk assumptions in the analyses in
NUREG-1738 to site-specific conditions at SONGS; and has determined
that the risk values in NUREG-1738 bound the risks presented by SONGS.
In addition, the significant decay of short-lived radionuclides that
has occurred since the January 2012 shutdown provides assurance in
other ways. As indicated by the results of research conducted for
NUREG-1738 and more recently, for NUREG-2161, ``Consequence Study of a
Beyond-Design-Basis Earthquake Affecting the Spent Fuel Pool for a U.S.
Mark I Boiling Water Reactor'' (ADAMS Accession No. ML15255A365), while
other consequences can be extensive, accidents from SFPs with
significant decay time have little potential to cause offsite early
fatalities, even if the formal offsite radiological EP requirements
were relaxed. The SCE's analysis of a beyond-design-basis accident
involving a complete loss of SFP water inventory, where adequate fuel
handling building air exchange with the environment and air cooling of
the stored fuel is available, shows that by August 31, 2014, air
cooling of the spent fuel assemblies was sufficient to keep the fuel
within a safe temperature range, indefinitely, without fuel cladding
damage or offsite radiological release.
The only analyzed beyond-design-basis accident scenario that
progresses to a condition where a significant offsite release might
occur, involves the very unlikely event where the SFP drains in such a
way that all modes of cooling or heat transfer are assumed to be
unavailable, which is postulated to result in an adiabatic heatup of
the spent fuel. The SCE's analysis of this beyond-design-basis accident
shows that as of October 12, 2014, more than 17 hours would be
available between the time the fuel is initially uncovered (at which
time adiabatic heatup is conservatively assumed to begin), until the
fuel cladding reaches a temperature of 1652 degrees Fahrenheit ([deg]F)
(900 [ordm]C), which is the temperature associated with rapid cladding
oxidation and the potential for a significant radiological release.
This analysis conservatively does not include the period of time from
the initiating event causing a loss of SFP water inventory until all
cooling means are lost.
The NRC staff has verified SCE's analyses and its calculations. The
analyses provide reasonable assurance that in granting the requested
exemptions to SCE, there is no design-basis accident that will result
in an offsite radiological release exceeding the EPA PAGs at the
exclusion area boundary. In the unlikely event of a beyond-design-basis
accident affecting the SFP that results in a complete loss of heat
removal via all modes of heat transfer, there will be well over 10
hours available before an offsite release might occur and, therefore,
at least 10 hours to initiate appropriate mitigating actions to restore
a means of heat removal to the spent fuel. If a radiological release
were projected to occur under this unlikely scenario, a minimum of 10
hours is considered sufficient time for offsite authorities to
implement protective actions using a CEMP approach to protect the
health and safety of the public.
Exemptions from the offsite EP requirements in 10 CFR part 50 have
previously been approved by the NRC when the site-specific analyses
show that at least 10 hours are available following a loss of SFP
coolant inventory accident with no air cooling (or other methods of
removing decay heat) until cladding of the hottest fuel assembly
reaches the zirconium rapid oxidation temperature. The NRC staff
concluded in its previously granted exemptions, as it does with the
SCE-requested EP exemptions, that if a minimum of 10 hours are
available to initiate mitigative actions consistent with plant
conditions, or if needed, for offsite authorities to implement
protective actions using a CEMP approach, then formal offsite
radiological emergency plans, required under 10 CFR part 50, are not
necessary at permanently shutdown and defueled power reactors.
Additionally, in its letters to the NRC dated October 6, 2014, and
December 15, 2014, SCE described the SFP makeup strategies that could
be used in
[[Page 33562]]
the event of a catastrophic loss of SFP inventory. The multiple
strategies for providing makeup water to the SFP include: using
existing plant systems for inventory makeup; an internal strategy that
relies on installed fire water pumps and service water or fire water
storage tanks; or an external strategy that uses portable pumps to
initiate makeup flow into the SFPs through a seismic standpipe and
standard fire hoses routed to the SFPs or to a spray nozzle. These
strategies will continue to be required as a license condition.
Considering the very low probability of beyond-design-basis accidents
affecting the SFP, these diverse strategies provide defense-in-depth
and time to provide additional makeup or spray water to the SFP before
the onset of any postulated offsite radiological release.
For all the reasons stated above, the NRC staff concludes that
application of certain requirements in 10 CFR 50.47(b), 10 CFR
50.47(c)(2), and 10 CFR part 50, appendix E, as summarized in the table
at the end of this document, is not necessary to achieve the underlying
purpose of these regulations and, therefore, satisfies the special
circumstances in 10 CFR 50.12(a)(2)(ii). The staff further concludes
that the exemptions granted by this action will maintain an acceptable
level of emergency preparedness at SONGS and provide reasonable
assurance that adequate offsite protective measures, if needed, can and
will be taken by State and local government agencies using a CEMP
approach, in the unlikely event of a radiological emergency at the
SONGS facility. Since the underlying purposes of the rules, as
exempted, would continue to be achieved, even with the elimination of
the requirements under 10 CFR part 50 to maintain formal offsite
radiological emergency plans and the reduction in the scope of the
onsite EP activities at SONGS, the special circumstances required by 10
CFR 50.12(a)(2)(ii) exist.
E. Environmental Considerations
In accordance with 10 CFR 51.31(a), the Commission has determined
that the granting of these exemptions will not have a significant
effect on the quality of the human environment, as discussed in the NRC
staff's Environmental Assessment and Finding of No Significant Impact
published on April 17, 2015 (80 FR 21271).
IV. Conclusions
Accordingly, the Commission has determined, pursuant to 10 CFR
50.12(a), that SCE's request for exemptions from certain EP
requirements in 10 CFR 50.47(b), 10 CFR 50.47(c)(2), and 10 CFR part
50, appendix E, Section IV, and as summarized in the table at the end
of this document, are authorized by law, will not present an undue risk
to the public health and safety, and are consistent with the common
defense and security. Also, special circumstances are present.
Therefore, the Commission hereby grants SCE exemptions from certain EP
requirements of 10 CFR 50.47(b), 10 CFR 50.47(c)(2), and 10 CFR part
50, appendix E, Section IV, as discussed and evaluated in detail in the
staff's safety evaluation dated June 4, 2015. The exemptions are
effective as of June 4, 2015.
Dated at Rockville, Maryland, this 4th day of June, 2015.

------------------------------------------------------------------------
10 CFR 50.47 NRC staff basis for exemption
------------------------------------------------------------------------
10 CFR 50.47(b). The NRC is granting In the Statement of
exemption from portions of the rule Considerations (SOC) for the
language that would otherwise require final rule for emergency
offsite emergency response plans. planning (EP) requirements for
independent spent fuel storage
installations (ISFSIs) and for
monitor retrievable storage
(MRS) facilities (60 FR 32430;
June 22, 1995), the Commission
responded to comments
concerning offsite EP for
ISFSIs or an MRS and concluded
that, ``the offsite
consequences of potential
accidents at an ISFSI or an
MRS would not warrant
establishing Emergency
Planning Zones.''
In a nuclear power reactor's
permanently defueled state,
the accident risks are more
similar to an ISFSI or an MRS
than an operating nuclear
power plant. The EP program
would be similar to that
required for an ISFSI under
Section 72.32(a) of 10 CFR
when fuel stored in the spent
fuel pool (SFP) has more than
5 years of decay time and
would not change substantially
when all the fuel is
transferred from the SFP to an
onsite ISFSI. Exemptions from
offsite EP requirements have
previously been approved when
the site-specific analyses
show that at least 10 hours is
available from a partial drain-
down event where cooling of
the spent fuel is not
effective until the hottest
fuel assembly reaches the
zirconium ignition temperature
of 900 degrees Celsius
([deg]C). The technical basis
that underlies the approval of
the exemption request is based
partly on the analysis of a
time period in which spent
fuel stored in the SFP is
unlikely to reach the
zirconium ignition temperature
in less than 10 hours. This
time period is based on a heat-
up calculation which uses
several simplifying
assumptions. Some of these
assumptions are conservative
(adiabatic conditions), while
others are non-conservative
(no oxidation below 900
[deg]C). Weighing the
conservatisms and non-
conservatisms, the staff
judges that this calculation
reasonably represents
conditions that may occur in
the event of an SFP accident.
The staff concluded that if 10
hours were available to
initiate mitigative actions,
or if needed, offsite
protective actions using a
comprehensive emergency
management plan (CEMP), formal
offsite radiological emergency
plans are not necessary for
these permanently defueled
nuclear power reactor
licensees.
[[Page 33563]]
As supported by the licensee's
SFP analysis, the staff
believes an exemption from the
requirements for formal
offsite radiological emergency
plans is justified for a
zirconium fire scenario
considering the low likelihood
of this event together with
time available to take
mitigative or protective
actions between the initiating
event and before the onset of
a postulated fire.
The SCE analysis has
demonstrated that the
radiological consequences of
design-basis-accidents (DBAs)
will not exceed the limits of
the U.S. Environmental
Protection Agency's (EPA's)
Protective Action Guides
(PAGs) at the exclusion area
boundary. These analyses also
show that as of October 12,
2014, in the unlikely event of
a beyond DBA where the hottest
fuel assembly adiabatic heat-
up occurs, 17.8 hours is
available to take mitigative
or, if needed, offsite
protective actions using a
CEMP from the time the fuel is
uncovered until it reaches the
auto-ignition temperature of
900 [deg]C.
SCE furnished information to
supplement its exemption
request concerning its SFP
inventory makeup strategies.
The multiple strategies for
providing makeup to the SFP
include: using existing plant
systems for inventory makeup;
an internal strategy that
relies on installed fire water
pumps (two motor-driven and
one diesel-driven) and service
and firewater storage tanks;
or an external strategy that
uses portable pumps to
initiate make-up flow into the
pools through a seismic
standpipe and standard fire
water hoses routed either over
the pools' edges or to spray
nozzles. SCE further provides
that designated on-shift staff
is trained to implement such
strategies and they have plans
in place to mitigate the
consequences of an event
involving a catastrophic loss-
of-water inventory
concurrently from both San
Onofre Nuclear Generating
Station (SONGS), Units 2 and 3
SFPs. It is estimated that it
would take approximately 55
minutes to deliver flow to one
pool, with an additional 35
minutes to provide water to
the second pool without having
to relocate the trailer-
mounted pump. Relocation of
the trailer-mounted pump, if
required, would take
approximately 30 additional
minutes. The SCE will maintain

definition of ``hostile

directed toward a nuclear

This definition is based on
the definition of ``hostile

Bulletin 2005-02, ``Emergency
Preparedness and Response

Events,'' dated July 18, 2005
(ADAMS Accession No.

2005-02 is not applicable to
nuclear power reactors that
have permanently ceased
operations and have certified
that fuel has been removed
from the reactor vessel. SCE
certified that it had
permanently ceased operations
at SONGS Units 2 and 3 and
that all fuel at those units
had been removed from the
reactor vessels. Therefore,
the enhancements for hostile
actions required by the 2011
EP Final Rule are not
necessary for SONGS in its
permanently shut down and
defueled status.
Additionally, the NRC excluded
non-power reactors from the
definition of ``hostile
action'' at the time of the
2011 rulemaking because, as
defined in 10 CFR 50.2, a non-
power reactor is not
considered a nuclear power
reactor and a regulatory basis
had not been developed to
support the inclusion of non-
power reactors in the
definition of ``hostile
action.'' Similarly, a
decommissioning power reactor
or ISFSI is not a ``nuclear
reactor'' as defined in the
NRC's regulations. Like a non-
power reactor, a
decommissioning power reactor
also has a lower likelihood of
a credible accident resulting
in radiological releases
requiring offsite protective
measures than does an
operating reactor.
Although this analysis provides
a justification for exempting
SONGS from ``hostile action''
related requirements, some EP
requirements for security-
based events are maintained.
The classification of security-
based events, notification of
offsite authorities and
coordination with offsite
agencies under a CEMP concept
are still required.

The intent of submitting
exercise scenarios at an
operating power reactor site
is to check that licensees
utilize different scenarios in
order to prevent the
preconditioning of responders

decommissioning power reactor

events that could occur and,
as such, the previously
routine progression to general

not applicable.
