Dear Mr. Mangan:
SUBJECT:
SAFETY EVALUATION - APPENDIX R, FUI L COVERAGE DETECTION AND SUPPRESSION SYSTEMS (TAC 53390)
Re:
Nine Mile Point Nuclear Station, Unit No.
1 Generic Letter 83-33, dated October 19, 1983, stated that to satisfy the requirements of Subsections III.G.2.b., III.Ci.2.c and III.G.2.e of Appendix R
to 10 CFR Part 50, fire detectors and automatic suppression systems need to be installed "throughout" the fire area.
By letter dated December 22, 1983, you requested an exemption from these requirements, as interpreted in GL 83-33, for the Reactor Building.
At the Appendix R Lessons Learned Workshop held in Region I on April 18, 1984, the NRC informed the industry of a draft revised interpretation of the above noted subsections that would accept partial coverage detection and automatic suppression systems that were supported by a fire hazards analysis as meeting the requirements of the subsections.
Accordingly, by letter dated May 11, 1984, you withdrew the exemption request dated December 22, 1983.
However, the supporting analysis for the partial coverage detection and suppression systems remained for staff review and approval.
During the period January 21-25, 1985, the NRC inspected the facility and reviewed your analysis for the reactor building.
The inspection team requested additional information, and the issues were referred to NRR for resolution.
By letter dated February 11, 1985, you provided the additional information requested by the inspection team.
The above-mentioned revised interpretation was approved by the Commission on March 6, 1986 (SECY 85-306/306B).
Therefore, we have evaluated the lack of full coverage detection and suppression systems for compliance with this interpretation, and find it acceptable.
In addition, we find your Fire Break BiosieoiiO 8SO806 PDR ADOCK 05000220 F
AUG 06 1gas C. V. Mangan Zone concept to be acceptable.
The Safety Evaluation supporting our findings is enclosed.
Sincerely, ORIGIMI SIGHED BY John A. Zwolinski, Director BWR Project Directorate 0'1 Divisio'n of BWR Licensing
