NUCLEAR REGULATORY COMMISSION
[Docket No. 50-272]
PSEG Nuclear, LLC; Salem Nuclear Generating Station, Unit No. 1;
Exemption
1.0 Background
PSEG Nuclear, LLC (PSEG or the licensee) is the holder of Facility
Operating License No. DPR-70 which authorizes operation of the Salem
Nuclear Generating Station (Salem), Unit No. 1. The license provides,
among other things, that the facility is subject to all rules,
regulations, and orders of the U.S. Nuclear Regulatory Commission (NRC,
the Commission) now or hereafter in effect.
The facility consists of a pressurized-water reactor located in
Salem County in the State of New Jersey.
2.0 Request/Action
Title 10 of the Code of Federal Regulations (10 CFR), Sec. 50.48
requires that all nuclear power plants licensed to operate prior to
January 1, 1979, have a fire protection plan that satisfies 10 CFR Part
50, Appendix A, General Design Criterion (GDC) No. 3, ``Fire
Protection.'' Appendix R to 10 CFR Part 50, ``Fire Protection Program
for Nuclear Power Facilities Operating Prior to January 1, 1979,''
hereinafter referred to as ``Appendix R,'' establishes fire protection
requirements to satisfy GDC 3. Furthermore, 10 CFR 50.48(b)
specifically requires that all nuclear power plants licensed to operate
prior to January 1, 1979, implement fire protection features described
in Appendix R, Section III.G.
Appendix R requires that, if a licensee cannot meet the separation
criteria delineated in Section III.G.2, and if redundant trains of safe
shutdown cables or equipment are in the same fire area, the licensee
must implement the alternative shutdown requirements of Section
III.G.3. Section III.G.3 requires that plants have a shutdown
capability independent of the area where redundant trains are located,
and further requires that the area with redundant trains have an
automatic fire detection and fixed fire suppression system. In
addition, a Federal court decision \1\ has held that, if a licensee
implements the requirements of Section III.G.3, the licensee must also
comply with Section III.L of Appendix R. Section III.L requires that
the licensee assume that offsite power is lost for a fire in a fire
area crediting Section III.G.3 alternative shutdown.

\1\ Connecticut Light and Power, et al., v. NRC, 673 F2d. 525
(D.C. Cir. 1982).
---------------------------------------------------------------------------
Salem, Unit No. 1, began power operations prior to January 1, 1979.
Therefore, the technical requirements of Appendix R, including Sections
III.G and III.L, are directly applicable to Salem, Unit No. 1.
By letter dated May, 1, 2002, as supplemented on August 15, 2002,
PSEG requested an exemption from Appendix R, Section III.G.3, fixed
suppression requirements for Fire Areas 1(2)-FA-AB-64B (Reactor Plant
Auxiliary Building, 64' Elevation) and 1(2)-FA-AB-84C (11 and 21
Component Cooling Water (CCW) System pump and heat exchanger areas, 84'
Elevation). In addition, the licensee requested an exemption from
Appendix R, Section III.L.3, loss of offsite power requirements for
Fire Areas 1(2)-FA-AB-64B and 1(2)-FA-AB-84B (Reactor Plant Auxiliary
Equipment Area, 84' Elevation).
On July 20, 1989, the Commission granted an exemption from the
technical requirements of Appendix R, Section III.G.2, to the extent
that Fire Areas 1(2)-FA-AB-64B and 1(2)-FA-AB-84B are not protected by
automatic fire suppression systems. However, because these areas are
being reclassified as alternate shutdown (Section III.G.3) fire areas,
this exemption supercedes the specific exemptions granted on July 20,
1989, for Fire Areas 1-FA-AB-64B and 1-FA-AB-84B.
3.0 Discussion
Pursuant to 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 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) when special circumstances are present. Special circumstances exist
if the application of the technical requirements of 10 CFR part 50, is
not necessary to achieve the underlying purpose of the regulation. The
underlying purpose of Sections III.G.3 and III.L.3 of Appendix R to 10
CFR part 50 is to provide reasonable assurance that at least one means
of achieving and maintaining safe shutdown conditions will remain
available during, and after, any postulated fire.
Fire Area 1-FA-AB-64B
PSEG requested an exemption from the fixed suppression requirement
of Appendix R, Section III.G.3, and the loss of offsite power
requirement of
[[Page 38726]]
Appendix R, Section III.L for Fire Area 1-FA-AB-64B. This area contains
waste gas compressors, waste gas tanks, storage tank recirculation
pumps, a laundry pump, a chemical drain tank pump, and holdup tanks and
pumps.
Fire Area 1-FA-AB-64B is made up of multiple rooms that are
separated by reinforced concrete barriers. Each room contains either a
single component or groups of similar components. The area boundaries
are also constructed of reinforced concrete. In-situ combustibles in
the fire area consist of lubricating oil in pumps and motors, paper,
electrical cabinet internals, and cable insulation. A fire detection
system is installed throughout the area except in the Holdup Tank
Rooms, No. 1 Pump Waste Monitor Hold-up Tank Pump Room, the Waste
Evaporator Feed Pump Room, and in unused space.
Manual fire alarm stations are provided in the area, and, along
with the fire detection system, annunciate in the Control Room. Manual
fire suppression capability is provided in the form of portable fire
extinguishers and manual hose stations. As previously stated, the
Commission granted an exemption for the lack of a fixed suppression
system on July 20, 1989.
Technical Evaluation for Fire Area 1-FA-AB-64B
Fire Area 1-FA-AB-64B credits alternative shutdown capability to
ensure post-fire safe shutdown. Therefore, because the area does not
have a fixed suppression system and offsite power is necessary to
accomplish safe shutdown, the licensee does not meet the technical
requirements of 10 CFR part 50, Appendix R, Sections III.G.3 and
III.L.3.
In its letter dated May 1, 2002, PSEG stated that a fire in this
area has the potential to result in a loss of the emergency diesel
generators (EDGs). However, the fire area contains no cables or
equipment that could cause the station to lose offsite power.
Therefore, offsite power would not be adversely affected by a fire, and
would be available to support safe shutdown activities. Alternative
shutdown capability, independent of the fire area, is provided to
ensure post-fire safe shutdown. Based on its review, the NRC staff
agrees that the licensee would be able to accomplish required safe
shutdown activities for a fire in this fire area using offsite power.
The fire area also has a low in-situ combustible loading with few
potential ignition sources. Areas containing significant amounts of
combustible materials also have a detection system to warn plant
operators in the event of a fire. If a fire were to ignite in this
area, the low combustible loadings, the inherent protection offered by
the concrete wall construction, and the limited propagation pathways,
would restrict the size of the fire. Fire detectors in the area would
alarm, and the site fire brigade would be able to extinguish the fire
using manual equipment. The NRC staff agrees that an automatic fire
suppression system is not necessary to control a fire with the
configuration of this fire area. Control Room operators would be able
to promptly detect a fire, and the station fire brigade would rapidly
respond and extinguish a fire in this area.
Therefore, the NRC staff concludes that the lack of fire
suppression specified in Section III.G.3, and the capability to
accommodate a loss of offsite power required by Section III.L.3, in
Fire Area 1-FA-AB-64B does not present an undue risk to the public
health and safety, and is not necessary to achieve the underlying
purpose of Sections III.G.3 and III.L.3 of Appendix R to 10 CFR Part
50.
Fire Area 1-FA-AB-84B
The licensee requested an exemption from the loss of offsite power
requirement of Section III.L.3 of Appendix R. The fire area contains
pumps, heat exchangers, tanks and control centers for the chemical and
volume control, CCW, safety injection, containment spray, auxiliary
feedwater, waste disposal, and spent pool cooling systems.
Fire Area 1-FA-AB-84B consists of multiple rooms separated by
reinforced concrete barriers. Each room contains either a single
component or groups of similar components. In-situ combustibles in the
area consist of lubricating oil in pumps and motors, flammable liquids
stored in cabinets, and cable insulation. The area contains few
ignition sources and few paths for fire propagation.
As previously stated, the Commission granted an exemption for the
partial fire detection system on July 20, 1989. Fire suppression is
provided for the auxiliary feedwater pumps by automatically actuated
pre-action sprinkler systems. Fire suppression is provided for the
charging pump area by a wet pipe sprinkler system.
Technical Evaluation of Fire Area 1-FA-AB-84B
The licensee does not meet the technical requirements of 10 CFR
Part 50, Appendix R, in that Fire Area 1-FA-AB-84B credits alternative
shutdown capability, and offsite power is required to accomplish safe
shutdown.
Although a fire in this area has the potential to result in a loss
of power from the EDGs to the 4160 Volt vital buses, the fire area
contains no cables or equipment that could cause the station to also
lose offsite power. Consequently, offsite power would not be adversely
affected by a fire, and would, thus, be available to support safe
shutdown activities in lieu of the EDGs. Alternative shutdown
capability, independent of the fire area, is provided through the
Chemical and Volume Control System cross-tie from the opposite unit to
ensure post-fire safe shutdown. Based on its review, the staff agrees
that the licensee would be able to accomplish required safe shutdown
activities for a fire in this fire area using offsite power.
Therefore, because the licensee would still be able to achieve safe
shutdown, the NRC staff concludes that the lack of capability to
accommodate a loss of offsite power required by Section III.L.3, in
Fire Area 1-FA-AB-84B does not present an undue risk to the public
health and safety, and is not necessary to achieve the underlying
purpose of Section III.L.3 of Appendix R to 10 CFR Part 50.
Fire Area 1-FA-AB-84C
The licensee requested an exemption from the fixed suppression
requirement of Section III.G.3 of Appendix R for Fire Area 1-FA-AB-84C.
This area contains the CCW Pump and Heat Exchanger.
The fire area boundaries are constructed of reinforced concrete.
The area has a low combustible material loading, consisting of
lubricating oil for the CCW pump and motor and cable insulation. The
area contains few fixed ignition sources.
An area-wide fire detection system is installed in the area. A
manual fire alarm station is provided in the corridor outside the room.
Both systems alarm in the Control Room. Manual fire suppression
capability is provided by portable fire extinguishers and manual hose
stations located in the corridor outside of the fire area. A fire in
this area could affect several systems required for redundant safe
shutdown. Therefore, alternative shutdown capability, independent of
the fire area, is provided to ensure post-fire safe shutdown.
Technical Evaluation of Fire Area 1-FA-AB-84C
The licensee does not meet the technical requirements of 10 CFR
Part 50, Appendix R, Section III.G.3, in that Fire Area 1(2)-FA-AB-84C
credits alternative shutdown capability and
[[Page 38727]]
does not have a fixed fire suppression system.
The fire area boundaries consist of reinforced concrete.
Alternative shutdown capability exists independent of the fire area to
ensure that the plant can be safely shutdown for a fire in this area.
The low combustible loadings, principally electrical cable insulation,
would result in a fire of limited size with slow growth
characteristics. In the event of a fire in the area, the fire detectors
would alarm and the fire brigade would extinguish the fire using manual
equipment. The NRC staff agrees that an automatic fire suppression
system is not necessary to control a fire in this configuration in this
fire area. Control Room operators could detect a fire, and the station
fire brigade would rapidly respond and extinguish a fire in this area.
Therefore, based on its review, the NRC staff concludes that the
lack of fixed fire suppression specified in Appendix R, Section
III.G.3, in Fire Area 1-FA-AB-84C does not present an undue risk to the
public health and safety, and is not necessary to achieve the
underlying purpose of the rule.
NRC Staff's Conclusion
The staff examined the licensee's rationale to support the
exemption requests and concludes that the fire protection measures
implemented in Fire Areas 1-FA-AB-64B, 1-FA-AB-84B, and 1-FA-AB-84C
provide reasonable assurance that at least one means of achieving and
maintaining safe shutdown conditions will remain available during and
after any postulated fire.
Therefore, the NRC staff concludes that, pursuant to 10 CFR
50.12(a)(2)(ii), there are special circumstances present, in that the
application of Sections III.G.2. and III.L.3 of 10 CFR Part 50,
Appendix R, is not necessary in order to achieve the underlying purpose
of those regulatory provisions.
4.0 Conclusion
Accordingly, the Commission has determined that, pursuant to 10 CFR
50.12(a), the exemption is authorized by law, will not present an undue
risk to the public health and safety, and is consistent with the common
defense and security. Also, special circumstances are present.
Therefore, the Commission hereby grants PSEG Nuclear, LLC an exemption
from 10 CFR, Part 50, Appendix R, Section III.G.3, fixed suppression
requirements for Fire Areas 1-FA-AB-64B and 1-FA-AB-84C; and 10 CFR,
Part 50, Appendix R, Section III.L.3, loss of offsite power
requirements for Fire Areas 1-FA-AB-64B and 1-FA-AB-84B for Salem, Unit
No. 1.
Pursuant to 10 CFR 51.32, the Commission has determined that the
granting of this exemption will not have a significant effect on the
quality of the human environment (68 FR 22742).
This exemption is effective upon issuance.
Dated at Rockville, Maryland, this 24 day of June 2003.
