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

Docket Nos. 50-277 PHILADELPHIA ELECTRIC COMPANY  : 50-278 APPLICATION FOR AMENDMENT OF FACILITY OPERATING LICENSES DPR-44 S DPR-56 Philadelphia Electric Company, Licensee under Facility Operating Idcenses DPR-44 and DPR-56 for Peach Bottom Atomic Power Station Unit Nos. 2 and '3 respectively, hereby requests that the Technical Specifications incorporated in Appendix A of the Operating Licenses be amended by revising certain sections as indicated by a vertical bar in the margin of the attached pages 234k and 2341 for Unit No. 2; and pages 127 and 251 for both Unit No. 2 and Unit No. 3. Pages 234m and 234n for Unit No. 2 are

included due to redistribution of material on the revised pages.

A discussion of each of the requested changes is set forth below.

Change 1 During the recent Unit No. 2 refueling outage (Sept. - Oct.,

1978) shock suppressors were added to the Residual Heat Removal (RHR) System and to the Reactor Water Clean-up (RWCU) System.

The shock suppressors added to the RHR system were part of the installation of ficw control valves in two of the RF3 loops.

These valves were installed for use during shutdown cooling. The shock suppressor added to the RWCU system was installed to reduce piping stresses associated with the Design Basis Earthquake.

Therefore, pursuant to Technical Specification 3.11.D.5, which allows snubbere to be added to safety related systems without prior License Amendment provided that a revision to Table 3.11.D.1 is included with the next License Amendment request, it is requested that Table 3.11.D.1 of Unit No. 2 be revised to reflect the addition of the above referenced shock suppressors.

Also included in the changes to the snubber table are several corrections of typographical errors.

Change 11 ,

The Peach Bottom High Pressure Service Water (HPSW) System is designed to maintain the service water pressure on the discharge of the Residual Heat Removal (RHR) heat exchanger higher than the pressure on the reactor coolant system side to preclude leakage of radioactive material into the cooling water. To assure that the HPSW system meets this design criteria Technical Specification 4.5.B.1 (b) requires quarterly testing of the HPSW pumps to verify their capability to deliver 4500 gpm at a discharge pressure of 280 psig (existing Technical Specifications) . The required discharge pressure was established by an analysis, conducted by the Peach Bottom Architect Ennineer, of HPSW system operation in conjunction with all modes of RHR system operation.

Subsequent to this analysis, modifications have been completed which substantially reduce the pressure on the RHR side (reactor coolant side) of the RER heat exchanger during all operating modes. This pressure reduction is the result of the installation of flow restricting orifices and drag valves upstream of the heat exchangers. An analysis of RHR and HPSW pres sures (as was conducted for the existing Technical Specification HPSW pump requirements issued on February 12, 1975 as Amendment Nos. 5 and 3 to Facility Operating Licenses DPR-44 and DPR-56 respectively), considering all modes of operation, indicates that a HPSW pump discharge pressure of 233 psig is sufficient to preclude leakage of radioactive material into the cooling water. This revised pressure limit includes the same margins for instrument accuracy and river water level variation included in the previous limit.

In.accordance with the above discussion, Section 4.5.B. 1 (b) should be changed to set the minimum pressure of the HPSW pump discharge at 233 psig.

Change III section 6.5.2.8 of the Technical Specification addresses audits of facility activities, however, the language of 6.5.2.8.a, 6.5.2.8.c. and 6.5.2.8.d. suggests complete review rather than audit. The proposed change would revise the language by removing the word "all" in sections pertaining to audits, so that it is descriptive of an audit function rather than a complete review and would bring the language of the affected sections into conformance with that in the Standard Technical Specifications as published in NUREG 0123 Rev. 1, April 1, 1978.

Since none of the changes pertaining to Unit No. 2 involves a safety consideration and some are editorial or administrative in nature, pursuant to 10 CFR 170.22, Philadelphia Electric Company proposes that the Application for Amendment for Unit No. 2 be considered a Class II Amendment. Since the changes for Unit No. 3 are a duplicate of changes requested for Unit No.

2, pursuant to 10 CFR 170.22,, Philadelphia Electric Company proposes that the Application for Amendment for Unit No. 3 be considered a Class I Amendment.

-4_

The Plant Operation Review Committee and the operation and Safety Review Committee have reviewed these proposed changes 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, PHILADELPHIA ELECTRIC COMPANY
