_(11 amended) SE2M2 Description 11-198. 199 2 Revise items 2 and 3 of section 11-6.2,6 to provide the basis for Unit 2 internal conduit fire seals by taking credit for automatic or manually actuated supp-ression system coverage on both sides of the fire barr-ier in addition to detection system coverage.

Addition:

Manually actuated fire suppression systems are install-ed in both the Units 1 and electrical switchgear ro-oms (83.96,103). These are the only plant areas where the primary fixed fire suppression systems required for separation of redundant safe shutdown cables and comp-onents are manually actuated. in the Unit 1 switchgear rooms. the suppression systte o not provide area-wide coverage and hence are not cte .ted for enabling condu-its penetrating fire barriers associated with these rooms to be sealed on one side (only) of the barrier.

However. in Unit 2. the suppression systems are desig-ned and installed to provide area-wide coverage.

Therefore, in conjunction with the fire detection system coverage, which provides early warning alarm annunciation of a fire in it's incipient stage for app-repriate fire brigade response, the manually actuatad suppression systems installed in the Unit 2 switchgear rooms provide a level of protection commensurate with automatically actuated systems, Based on the equivalent level of protection afforded by the manually actuated systems in Unit 2. conduits penetrating fire barriers associated with the Unit 2 switchgear rooms can be sealed on one side (only) of the barrier with no adverse affect on fire safe shutdown capability.

Additionally, this approach to installing internal conduit fire seals represents cost savings associated with design, installation and long-term surveiilance for approximately 300 fire seals.

FPR Change Request Number: FP-91 2.0 SER/SSER Impact: No II-198. 199 3 Revise items 2 and 3 of section 11-6.2.6 by referring l to Appendix B of the FPR plus FSAR section 9.5.1.6.2. i to provide for future FHA evaluations associated with internal conduit fire seals, Correction:

This change maintains consistency in the FPR text by providing reference to Appendix B for instances where FHA evaluations are used to demonstrate compliance with with BTP APCSB 9.5-1. Appendix A.

" Conduit Fire Protection Research Program" as the basis for internal conduit seal evaluations. Also makes minor editorial corrections to the " FHA Evaluation Matrix".

Addition: j Since the " Conduit Fire Protection Research Dro?rss" used actual fire testing to substantiate it'c concius-ions, incorporation of these results into the CPSES design basis for internal conduit fire seals meets the the guidelines established by Appendix A to GTP APCSB 9.5-1 and Generic Letter 86-10. Additicuolly, the issues identified by NRC Information Notice 88-04 reg-arding substantiation of penetrativ. mal configuration by test are likewise satisfied by the Wisconsin Electr-ic study. Furthermore, the NRC's Safety Evaluation Rep-ort issued on October 23, 1989 in response to Wisconsin

Attachment 2 to TXX-92327 Page 8 of 9 CPSES FPR REVISION 6 DETAILED DESCRIPTION FPR Page (n Amended) Sten Description Electric's submittal of the " Conduit Fire Protection Research Program" provided concurrence with the conclu-sions of the study. Therefore, sufficient regulatory acceptance of the study exists to justify it's incorp-oration into the CPSES design basis. Lastly, reduction of rquired conduit fire seals offers long term cost savings in that actions necessary for surveil',ance are in turn eliminated (ie removal of junction ',ox covers, conduit fittings, etc.).
