INDIAN POINT NUCLEAR GENERATING UNIT NO. 3 DOCKET NO. 50-286 By letter dated July 24, 2006, Request for Revision of Existing Exemptions from [Title 10 of the Code of Federal Regulations] (10 CFR Part 50), Appendix R: One-Hour Hemyc Electrical Raceway Fire Barrier System, Fire Areas ETN-4 and PAB-2, Entergy Nuclear Operations, Inc.
(Entergy or the licensee) requested a revision to existing exemptions for Indian Point Nuclear Generating Unit No. 3 (IP3), from the requirements of 10 CFR Part 50, Appendix R, Fire Protection Program for Nuclear Power Facilities Operating Prior to January 1, 1979, for Fire Areas ETN-4 and PAB-2. Specifically, the licensee requests that the existing exemptions for Fire Zones 7A, 60A, and 73A in the above fire areas be revised to credit a 30-minute fire resistance rating for the installed Hemyc electrical raceway fire barrier system (ERFBS) in lieu of the previously credited 1-hour rating.
The Nuclear Regulatory Commission (NRC) staff is reviewing the submittal in order to determine if the reduced Hemyc ERFBS fire resistance rating will continue to meet the intent of the fire protection program in accordance with 10 CFR Part 50, Section 48 (10 CFR 50.48),
Fire protection, and NUREG-0800, SRP 9.5.1, Fire Protection Program," and has the following questions:
1.
Which specific NRC-tested configurations were the IP3 modified Hemyc ERFBS configurations compared to? Are the modified configurations comparable to the industry-sponsored Hemyc test configurations? Do the results of the industry-sponsored Hemyc tests also support the licensees conclusion on the 30-minute rating of the modified Hemyc ERFBS at IP3?
2.
The licensee indicated that administrative control measures are in place to limit transient combustibles in Fire Areas ETN-4 and PAB-2 to moderate quantities. Clarify exactly how much of which type of transient combustibles are allowed? Also, are there any specific locations in the above fire areas where transient combustibles are not allowed?
3.
What type, how much, and how close in proximity are fixed combustibles located in the area of the credited Hemyc ERFBS in Fire Areas ETN-4 and PAB-2?
4.
What fire scenarios are being considered for Fire Zone 1? What is the post-fire safe-shutdown strategy for Fire Zone 1; specifically under what circumstances must the credited Hemyc ERFBS survive the postulated fire?
5.
Are there drains or dikes provided in the areas of the component cooling water (CCW) pumps? If not, can the partial height Appendix R wall contain a spill of combustible fluid from entering or leaving the CCW Pump 33 area? How high is the partial-height wall?
6.
Is there a potential for combustible fluids to drip from the 55 elevation into the CCW pump areas? Or a potential for a fire in the 15 elevation directly below the CCW pump areas that could impact both trains of CCW pumps?
