SUBJECT:
WATTS BAR NUCLEAR PLANT, UNIT 2 - REQUEST FOR ADDITIONAL INFORMATION REGARDING FINAL SAFETY ANALYSIS REPORT AMENDMENT RELATED TO SECTION 9.5.1 "FIRE PROTECTION SYSTEM" GROUP 8 (TAC NO. ME3091)
Dear Mr. Skaggs:
By letters dated July 16, August 9,20, and 30, November 5, and December 1,18, and 20,2010; and January 14, March 16 (two letters), March 31, May 6, 18, and 26, June 7 and 17, August 5 and 15, and November 30,2011, Tennessee Valley Authority (TVA) responded to requests for additional information (RAls) relating to the Fire Protection Report for Watts Bar Nuclear Plant.
The U.S. Nuclear Regulatory Commission (NRC) staff has been reviewing the information provided by TVA in support of the operating license application for WBN Unit 2.
After reviewing the responses provided by TVA and the Fire Protection Report, the NRC staff has determined that additional information is needed to complete its review.
Based on discussions with your staff, TVA stated to NRC staff that responses would be completed by April 13, 2012, along with the next submittal of the Fire Protection Report. If the response will not be completed by that date, a written request to the NRC for an extension, including justification, is required.
If you should have any questions, please contact me at 301-415-2048.

REQUEST FOR ADDITIONAL INFROMATION WAITS BAR NUCLEAR PLANT. UNIT 2 FIRE PROTECTION REPORT TENNESSEE VALLEY AUTHORITY DOCKET NO. 50-391 A public meeting was held on February 2, 2012, between the U.S. Nuclear Regulatory (NRC) staff and representatives from Tennessee Valley Authority (TVA) regarding the ongoing review of the Watts Bar Nuclear Plant Unit 2 Fire Protection Report (FPR). During the meeting, TVA presented sample fire protection evaluations to the NRC staff. The following questions relate to those samples. Specifically the questions focused on TVA's proposed revision to Part VII, Section 2.9 Deviations. Information to address the following questions is needed by the staff to complete the review. These questions were discussed with TVA via teleconference on February 27,2012.
RAI FPR VII-26 The new evaluations have removed discussion of plant trip initiators in the room. For each room, discuss plant trip initiators in that room. Describe the scenario that would have to occur for a fire to cause a plant trip, affect redundant trains of fire safe shutdown equipment or cables, or both.
RAI FPR VII-27 Discuss the possibility of room-to-room fire spread, in particular for unrated fire barriers and for adjacent rooms that contain redundant safe shutdown equipment.
RAI FPR VII-28 For all equipment determined not to be significant ignition sources, identify the basis documents, as references, that support this conclusion.
RAI FPR VII-29 Verify the equipment in room 676.0-A1 only contains equipment necessary for cold shutdown.
