PHILADELPHIA ELECTRIC COMPANY I 2301 MARKET STREET P.O. BOX 8699 PHILADELPHIA. PA.19101 (215) 841-4 boo January 19, 1981 Mr. Robert W. Reid Branch Chief - Operating Reactors Branch #4 Division of Licensing US Nuclear Regulatory Commission Washington, DC 20555

Dear Mr. Reid:

RE: Peach Bottom Atomic Power Station - Unit 2 Docket Number 50-277 .

Philadelphia Electric Company, Licensee under Facility Operating License DPR-44 for Peach Bottom Unit #2, hereby requests that the Technical Specification contained in Table 3.2.A (on page 61) of Appendix A of the Operating License be temporarily amended as follows. The trip level setting prescribed for main steam line tunnel exhaust duct high temperature be temporarily suspended for a period of approximate.ly five minutes to allow for the air temperature surge which will result from the return of the normal ventilation system. This relaxation is necessary to avoid an unnecessary scram and reactor system isolation. The purpose of this instrumentation is to provide for closure of the main steam isolation valves in the event of a steam line break in this room. This instrumentation is redundant to the main steam line high radiation monitors and the mai steam line high flow safety instrumentation.

The Plant Operations Review Committee concurs in this temporary suspension of a technical specification and has discussed this matter with the NBC Site Inspector.

Very truly yourc, g/
