April 4, 2007 Tennessee Valley Authority ATTN: Mr. Preston D. Swafford Acting Chief Nuclear Officer and Executive Vice President 6A Lookout Place 1101 Market Street Chattanooga, TN 37402-2801
SUBJECT:
WATTS BAR NUCLEAR POWER PLANT, NOTIFICATION OF INSPECTION AND REQUEST FOR INFORMATION
Dear Mr. Singer:
On May 21-25, 2007, the NRC will perform the baseline Occupational Radiation Safety Inspection at Watts Bar, (NRC Inspection Procedures 71121.01, 71121.02, 71122.02, and Radiation Safety Sections of 71151). Experience has shown that this inspection is resource intensive both for the NRC inspectors and your staff. In order 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, in order to minimize the number of additional documents requested during the preparation and/or the onsite portions of the inspection. The lead inspector has scheduled a two-day preinspection visit with your staff for April 24-26, 2007. The material requested will be reviewed and collected at that time.
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 lead inspector, Ruben Hamilton at (404) 562-4672.
In accordance with 10 CFR 2.390 of the NRCs Rules 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

The most recent inspection completed for the listed inspection procedures was performed is listed in parenthesis. Documentation is requested from the date of the previous inspection to the present.
We would prefer as much of the information as possible in electronic form. An index to the CD contents is also helpful. For those items requesting a list of documents/areas, the inspectors will select documents/areas from the list for on-site review. If any of the requested information is too burdensome to provide electronically or as hard copies during the bagman trip, simply indicate that the requested material is available for onsite review by the inspectors.
If you have any questions, please call Ruben Hamilton at 404-562-4672. Thank you in advance for all your effort in putting together this material.
