UNITED STATES NUCLEAR REGULATORY COMMISSION WASHINGTON, D.C. 20555-0001 October 4, 2010 Mr. R. M. Krich Vice President, Nuclear Licensing Tennessee Valley Authority 3R Lookout Place 1101 Market Street Chattanooga, TN 37402-2801 SUB~IECT: WATTS BAR NUCLEAR PLANT, UNIT 1 - SCHEDULE REGARDING THE LICENSE AMENDMENT REQUEST FOR TOTAL FLOODING AUTOMATIC CARBON DIOXIDE FIRE SUPPRESSION SYSTEM INSTALLED IN THE AUXILIARY INSTRUMENT ROOM (TAC NO. ME2532)
Dear Mr. Krich:
By letter dated October 30,2009 (Agencywide Documents Access and Management System Accession No. ML093080377), Tennessee Valley Authority (TVA) requested a license amendment concerning a change to the Watts Bar Nuclear Plant, Unit 1 fire protection program requirements. Specifically, this involves changing the design basis of the total flooding automatic carbon dioxide (C0 2 ) fire suppression system in the Auxiliary Instrument Room from a 50-percent CO 2 concentration to a 45-percent concentration, retaining the currently required 15-minute hold time to suppression a fire.
TVA requested the U.S. Nuclear Regulatory commission (NRC) to complete its review by October 30, 2010. The NRC performance goals for licensing actions is to complete 95-percent in less than 1 year and 100-percent in less than 2 years. It is very unlikely that NRC will complete its review by October 30, 2010.
If you have any questions regarding this issue, please feel free to contact me at (301) 415-3100.
