SUPPLEMENT N0. 4 TO THE SAFETY EVALUATI0ft 0F THE PEACH BOTTOM ATOMIC POWER STATION FIRE PROTECTION PROGRAF 1 PHILADELPHIA ELECTRIC COMPAfiY DOCKETS NOS. 50-277 ano 50-278 I.
INTRODUCTI0fl On May 23, 1979 we issued a Safety Evaluation Report (SER) of the Fire Protection Program at the Peach Bottom Atomic Power Station, Units Nos. 2 and 3.
The report contained a number of items which required staff approval prior to implementation and a number of items which were still under staff review. By letters dated August 14, Septenber 15 and October 10, 1980, we issued Supplements Nos.1, 2 and 3 to the SER which resolved certain of the outstandi.19 items. The purpose of this suoplement is to report the staff's findings of additional issues based on the sub-mittals by the Philadelphia Electric Company (licensee).
Each natter discussed in this supplement is identified by the same section number as was used in the SER.
II. EVALUATIOM 1.
FIRE DETECTI0fl SYSTEM - REMOTE ALAPJi LAMPS, SECTION 3.2.3(3)
In the SER, it was our concern that the fire detectors in the cable spreading room were obscured from view by other equipment and, therefore, the neon lamps which illuminate when the detector is in the alam mode were not readily visible. We recommended that the licensee perform a study to detemine the feasibility of in-stalling remote alarm lamps for. these detectors.
By letter dated October 31, 1980, the licensee proposed to provide a renote indi-cetor panel outside the cable spreading room.
Each snoke detector in the cable spreading room will have a lanp on the panel to indicate detector actuation.
Based on the licensee's proposal to provide a remote indicator panel for the cable spreading room fire detector system, we conclude that the licensee's proposal meets our recomendation and is, therefore, acceptable.
2.
FIRE DOORS, SECTION 3.2.6(2)
In the SER, it was our concern that the doors to the room containing the reactor feed pump turbine lube oil reservoir may not provide a 3-hour fire rating. We recommended that the licensee upgrade them to provide a 3-hour fire rating.
By letter dated October 31, 1980, the licensee verified that the existing doors are certified by Underwriters Laboratories as having a 3-hour fire rating.
8 01217OM7
PB-2/3 2-I Based on the licensee's verification that the doors have a 3-hour fire. rating, we conclude that the fire doors meet Section D.l(j) of Appendix A to BTP APCSB 9.5-1 and, therefore, are acceptable.
3.
H0SE TESTS, SECTION 3.2.12 l
In the SER, it was cur concern that the hose stored outside may not be tested regularly. By letter dated February 12, 1979, the licensee proposed to hydros statically test or replace all exterior' hose on a two-year interval. Our SER
(!!ay 23,1979) requested that the licensee evaluate the need to hydrostatically test all hose stored in outside hose cart houses annually at a pressure of 50 psi above maximum service pressure. This staff position was consistent with the Proposed Rule (Appendix R to 10 CFR) published in the FEDERAL REGISTER on May 29, 1980 (45 FR 36082).
By letter dated October 31, 1980, the licensee proposed to hydrostatically test or replace all exterior hoses annually. The liceasee also proposed to hydro-statically test or replace all interior hose at three-year intervals.
The final rule, published on November 19, 1980. revised this position.
It requires-that outside hose be tested annually at a pressure of 300 psi or 50 psi above the maximum operating pressure whichever is greater.
The provisions of the final rule regarding this issue were discussed with the licensee and he agreed to comply with the published requirements.
Conformance will be reflected in the Final Fire Protection Technical Specifications to be issued upon completion of required Appendix R ncdifications.
Therefore, we find that our requirements have been satisfied and this issue is resolved.
