7590-01 UNITED STATES NUCLEAR REGULATORY COMMISSION In the Matter of f
(GPUNUCLEARCORPORATIONAND Docket No. 50-219 JERSEY CENTRAL POWER & LIGHT COMPANY) i (Oyster Creek Nuclear Generating Station)
EXEMPTION l
I.
The GPU Nuclear Corporation and Jersey Central Power & Light Company (GPUN/thelicensee)aretheholdersofProvisionalOperatingLicenseNo, I
DPR-16, which authorizes operation of the Oyster Creek Nuclear Generating Station, (the facility) at steady state reactor core power levels not in excess of 1930 megawatts thermal. The license provides, among other things, that Oyster Creek Huclear Generating Station is subject to all rules, regulations, and Orders of the Consnission now or hereaf ter in effect.
The plant is a boiling water reactor (BWR) located at the licensee's site r
in Ocean County, New Jersey.
II.
On November 19, 1980, the NRC published a revised Code of Federal Regulations, Section 10 CFR 50.48 and a new Appendix R to 10 CFR Part 50 t
regarding fire protection features of nuclear power plants. The revised e
v,N[
Section 50.48 and Appendix R became effective on February 17, 1981. Section Ob III'ofAppendixRcontainsfifteen(15) subsections,letteredAthrough0, r>x 38 each of which specifies requirements for a particular aspect of the fire protection features at a nuclear power plant. One of these fifteen k
subsections, III.G, is the subject of this exemption request. Specifically,Section III.G requires that the plant have fire protection of shutdown capability.
-2 III.
By letter dated August 2B, 1986, the licensee requested exemptions from certain technical requirements of Section III.G of A g endix R to 10 CFR Part 50 for specific areas of the plant. The specific exemptions requested are as follows:
1.
An exemption is requested from the requirement of Section III.G.2 for not providing area wide automatic fire suppression in Fire Zone RB-FZ-10. Elcyation 51 feet.
2.
An exemption is requested from the requirement of Section III.G.2 for not providing area wide automatic fire suppression in Fire Zone RB FZ-1E, Elevation 23 feet.
3.
For the Fire Zone RB-FZ-1E elevation 23 feet, a second exemptior, is requested from the requirem,ent of Section III.G.2 for not providing specific protection for the reactor scram system circuitry in the fire zone.
4 For the Fire Zone RB-FZ-1E, elevation 23 feet, a third exemption is requested from the requirement of Section III.G.2 for not providing either additional separation from insitu combustibles or protection for CRD Hydraulic System Bypass Valve V-15-30.
l 5.
F.n the Fire Zone RB-FZ-1E elevation 23 feet, a fourth exemption is requested from the requiremcat of Section III.G.2 for not providing a one-hour fira barrier for drywell penetration box P-13.
6.
An exemption is requested from the requirement of Section III.G 2 for not providing area wide automatic suppression in Fire Zone RB-FX-1F, elevation (-19) feet.
7.
For Fire Zone RB-FZ-1F, elevation (-19) feet, a second exemption is requested from the requirement of Section III.G 2 for not previding either additional separation from insitu combustibles or protvetion for core spray system valve V-20-1.
8.
An exemption is requested from the requirement of Section III.G.2 i
for not providing a 3-hour rated fire barrier for the portion of circuit 14-25 that is located in Fire Zone TF-FZ-1B Turbine Lube Oil Storage, Pumping and Purification Areas.
9.
An exemption is requested from the requirements of Section III.G.2 and III.G.3 for not providing automatic fire detection in Fire Zone TB-FZ-11D.

- 10. An exemption is requested from the requirement of Section III.G.3 for not providing automatic fire detection in Fire Zone TB-FZ-11E.-
- 11. An exemption is requested from the requirement of Section III.G.2 Y
for not providing a 3-hour fire barrier for Train "A" electrical power system circuit 14-22.
- 12. An exemption has been requested from the requirement of Section III.G.2 for not providing automatic fire suppression for the corridor area of new Fire Zone OB-FZ-6B, which has been created out of the Fire Area OB-FA-6.
- 13. An exemption has been requested from the rea'!bement of Section 1
III.G 2 for not providing that at least one safe shutdown path needed to maintain hot shutdown is free of fire damage without any repair. The exemption is requested to allow minor repairs outside of Fire Area OB-FZ-6A-480 Volt Switchgear Room to provide the required hot shutdown capability for the new Fire Zone OB-FZ-6 e cr.ed out of Fire Aree OB-FA-6.
i 14 An exemption hat teen requested from the requirements of Section III.G.2.for not rovtding automatic fire detection in Fire Zone OB-FZ-8A Motor Genator Set Room.
15.
For the Fire Zone OB-FZ-8A, a second exemption is requested from the requirement of Section III.G.2 for not providing specific protection for the reactor recirculation valve circuits contained in this fire Zone.
'16.
An exemption is requested from the requirements of Section III.G.2 for not providing specific protection to reactor scram circuits located in Fire Zone OB-FZ-8C-Battery Room, Tunnel and Electrical Tray Room, elevatior 35 feet.
17.
For the Fire Zone OB-FZ-8C, a second exemption is requested from the provisions of Section III.G.2 for not providing specific protection to the reactor recirculation valve circuits contained in this fire zone.
The staff has reviewed the licensee's request and the supporting technical information contained in the licensee's August 25, 1986 letter, in a Safety
. Evaluation, dated June 25, 1990
. For the reasons set.out in that evaluation, the staff agrees with GPU Nuclear Corporation and in each case we have concluded that the requested exemptions are valid and should be granted.
IV.
Accordingly, the Commission has determined that, pursuant to 10 CFR 50.12, this exemption is authorized by law, will not present an undue risk to the
4 public health and safety, and is consistent with the common defense and security. The Comission has further determined that special circumstances, as set forth in 10 CFR 50.12(a)(2)(ii), are present justifying the exemption, namely that the application of the regulation in the particular circumstances 1
is not necessary to achieve the underlying purpose of the rule. The under-l lying purpose of this rule is to provide the plant with fire protection of shutdown capability. As a re! ult of the staff's review, the staff concludes that because modifications assure that sefe shutdown will occur for each
)
affected fire zone, strict compliance of the rule is not necessary to achieve j
fire protection shutdown capability. Accordingly, the Commission hereby grants an exemption as described in Section III above from the requirements of Section III.G of Appendix R to 10 CFR Part 50.
Pursuant to 10 CFR 51.32, the Commission has determined that the granting i
of this exemption will have no sier.ificant impact on the environment (55 FR 25752).
This exemption is effective upon issuance.
