APPLICATION FOR AMENDMENT ,

OF FACILITY OPERATING LICENSE DPR-44 Edward G. Bauer, J r.

BEFORE THE UNITED STATES NUCLEAR REGULATORY COMMISSION In the Matter of  :

Docket No. 50-277 PHILADELPHIA ELECTRIC COMPANY  :

APPLICATION FOR AMENDMENT OF FACILITY OPERATING LICENSE DPR-44 Philadelphia Electric Company, Licensee under Facility Operating License DPR-44 for Peach Botton Unit 2, hereby requests that the Technical Specifications contained in Appendix A of the Operating Licenses be amended by revising section 3.7.A.I.c as indicated by a vertical bar in the margin of attached page 165a.

The Licensee plans to conduct tests on Peach Botton Unit 2, following the refueling / torus modification outage, that will add heat to the containment suppression pool. The tests involve the manual opening of the main steam safety-relief valves to accommodate both a startup valve performance test, and a valve 1

discharge piping test. The latter test is related to the "T" quencher modification to the safety relief valve discharge pipe.

Technical Specification 3.7.A.1.c requires the suppression pool temperature to be reduced below 90*F within 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> of testing that adds heat to the suppression pool. The higher river water temperatures prevdlent at this time of the year would inhibit a temperature reduction below 90*F within the 24 hour2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> period. The inability to meet this temperature limitation would require Unit 2 to be removed from service, possibly jeopardising power reliability in our service area.

Accordingly, Philadelphia Electric Company proposes to change section 3.7.A.1.c to temporarily allow a period of 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> to reduce the pool temperature to 95'F and five days following completion of the testing to reduce the suppression pool temperature to 90*F. The safety analysis supporting a 95*F limit was submitted on August 1, 1978, as part of a Peach Botton Operating License Amendment Application proposing an increase in the suppression pool temperature limit. Additionally, the 95*F limit is consistent with the limit identified in the " Standard Technical Specifications - General Electiic Boiling Water Reactors", revision 2, August 1979, section 3.6.2.1.

Pursuant to 10 CFR 170.22 " Schedule of Fees for Facility License Amendment", Philadelphia Electric Company proposes that this Application for Amendment be considered a Class III-Amendment since the proposed change involves a single

safety issue.

j

The Plant Operation Review Committee and the Operation and Safety Review Committee have reviewed this proposed change to the Technical Specifications and have concluded that they do not involve an unreviewed safety question or a significant hazards consideration and will not endanger the health and safety of the public.

Respectfully submitted.

. PBAPS LIMITING _CONDITIONg FOR OPERATION SURVEILLANCE REQUIREMENTS C. Maximum suppression pool temperature:

1. During normal power operation, 90F.

2. During testing which adds heat to the suppression pool, the water temperature shall not exceed 10 F above normal power operation limit specified in (1) above. In connection with such testing, the pool temperature must be reduced to below the normal power operation limit specified in (1) l above within 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br />.*

3. The reactor shall be scrammed from any operating condition if the pool temperature reaches 110F. Power operation shall not be resumed until the pool temperature is reduced below the normal power operation limit specified in (1) above.

4. During reactor isolation conditions, the reactor pressure vessel shall be -

depressurized to less than 200 psig at normal cooldown rates if the pool temperature reaches 120F.

'

• To accommodate the Unit 2 post refueling outage testing rc4.': int the opening of the safety / relief valves during the summer of :990, the following shall apply in lieu of paragraph C.2 above: Daciad testing which adds heat to the suppression pool, the water temperature shall not exceed 100'F. In connection with such testing, the pool temperature shall be reduced'to 95'F within 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> of completion of the testing and to below the normal power operating-limit specified in C.1 above within 5 days of completion of the testing. This provision shall be applicable only for a period of 5 days following completion of-the summer of 1960 testing.
