Dear fir. Dauer:
TWambach VBenaroya Our letter dated flovember 24,1980 (D. G. Eisnhut, !!RC to all Power Reactor Licenseus) identified mechanical and electrical penetration seals through fire barriers as an open item for Peac.. Bottom, Units 2 and 2 It further stated that compliance with the electrical penetration seal design criteria specified by 10 CFR 50, Appendix R Section III M, and the fire resistance criteria for mechanical penetration seals identified in Section III G was necessary to resolve this issue. The schedule requirement (40 CFR 50.43) for ensuring adequate fire barrier protection Letween alternative shutdown systems is 30 months after flRC approval of the licensees proposed safe shutdown analysis.
In your flarch 20, 1981 letter, you proposed a 14 arch 1,1984 schedule for completing the alternative shutdown system which conforms with the intent of the !!RC's 30 mont.h schedule. On page 11, item E, of the ilarch 20, 1981 letter, you proposdd to examine and upgrade the fire barrier electrical penetration seals to meet the Appendix R design criteria by liovember 19, 1981. Yourneglected to propose a schedule for upgrading the mechanical penetration seals.
In lieu of the commitment made in your March 20, 1981 letter, you propose to substitute the following commitment, made in your October 14, 1981 letter, that addressees both electrical and mechanical penetration seals, and integrates the penetration seal issue with the fire barrier requirements for safe shutdown capabilities.
"The electrical and mechanical penetration seals on those barriers whose int ~egrity is required to ensure safe shutdown caoability will be upgraded to meet the design criteria identified in 10 CFR 50, Appendix R, Sections III G and III !!. The upgrade of the seals is currently in progress and will continue at a pace dependent on the availability of qualified seal designs. And identification of vital barriers by the safe shutdown analysis. Completion of the upgrado effort will be consistent with the schedule for implementing the alternative shutdown modifications (Itarch 1,1934)."

2 The revised commitment conforms with the flRC's requests in our Novenber 24, 1980 letter, and the design criteria required in 10 CFR 50, Appendix R,Section III G and III H, and the schedule required in 10 CFR 50.48 Therefore, we find the revised commitment to be acceptable.
The Fire Protection Program at Peach Cottom has progressed to appoint where the additional Tehhnical Specifications requested by our May 23,1979 Safety Evaluation, related to facility modifications required by implementation of the Fire Protection Program, should be submitted by Philadelphia Electric Company. Any Technical Specifications (TS) changes required by the penetration seals, discussed above, should be submitted with those TS required to implement the Alternate Safe Shutdown System.
Sincerely,
