UNITED STATES NUCLEAR REGULATORY COMMISSION REGION II 245 PEACHTREE CENTER AVENUE NE, SUITE 1200 ATLANTA, GEORGIA 30303-1257 May 9, 2011 Mr. R. M. Krich Vice President, Nuclear Licensing Tennessee Valley Authority 1101 Market Street, LP 3R-C Chattanooga, TN 37402-2801

SUBJECT:

WATTS BAR NUCLEAR PLANT NOTIFICATION OF INSPECTION AND REQUEST FOR INFORMATION

Dear Mr. Krich:

During the period of June 6-10, 2011, the NRC will conduct a baseline radiation safety inspection at the Watts Bar Nuclear Plant. The inspection will evaluate radiation protection activities in the Occupational Radiation Safety cornerstone using NRC Inspection Procedures (IP) 71124.02 Occupational ALARA Planning and Controls, 71124.03 In-Plant Airborne Radioactivity Control and Mitigation, 71124.08 Radioactive Solid Waste Processing and Radioactive Material Handling, Storage, and Transportation, and 71151 Performance Indicator Verification (Public Radiation Safety).

Most of these procedures went into effect at the beginning of 2010 and have not been performed at Watts Bar in their current form. Therefore the base date for documentation requested is from January 1, 2010.

To minimize the impact to your on-site resources and to ensure a productive inspection, we have enclosed a request for documents needed for this inspection. It is important that all of these documents are up to date and complete, thereby minimizing the number of additional documents requested during the preparation and/or the onsite portions of the inspection. The inspector has requested that the subject informational material be provided in compact disk (CD) format on or before May 27, 2011.

We have discussed the schedule for these inspection activities with your staff and understand that our regulatory contact for this inspection will be Jerry Bushnell of your organization. If there are any questions about this inspection or the material requested, please contact the inspector, Ruben Hamilton at (404) 997-4672.

TVA 2 In accordance with 10 CFR 2.390 of the NRC

=s ARules of Practice,@ a copy of this letter and its enclosure will be available electronically for public inspection in the NRC Public Document Room or from the Publicly Available Records (PARS) component of NRC's document system (ADAMS). ADAMS is accessible from the NRC Web site at http://www.nrc.gov/reading-rm.html (the Public Electronic Reading Room).

Sincerely, /RA/ Brian R. Bonser, Chief Plant Support Branch 1 Division of Reactor Safety
