SUBJECT:
WATTS BAR NUCLEAR PLANT - NOTIFICATION OF INSPECTION AND REQUEST FOR INFORMATION
Dear Mr. Shea:
From July 22-26, 2013, and April 12-16, 2013, the U.S. Nuclear Regulatory Commission (NRC) will perform a baseline Occupational and Public Radiation Safety inspection at the Watts Bar Nuclear Plant, (NRC Inspection Procedure 71124.01 Radiological Hazard Assessment and Exposure Controls, 71124.02 Occupational ALARA Planning and Controls, 71124.03 In-Plant Airborne Radioactivity Control and Mitigation, 71124.04 Occupational Dose Assessment, 71124.05 Radiation Monitoring Instrumentation, and 71151 Performance Indicator Verification (Occupational and Public Radiation Safety Cornerstones)).
To minimize the impact to your onsite 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 July 8, 2013.
We have discussed the schedule for these inspection activities with your staff and understand that our regulatory contact for this inspection will be Tommy Morgan (423) 365-1401 of your organization. If there are any questions about this inspection or the material requested, please contact the lead inspector Ruben Hamilton at (404) 997-4672 (ruben.hamilton@nrc.gov).
In accordance with Title 10 of the Code of Federal Regulations (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 Agencywide Documents Access and Management System (ADAMS). ADAMS is accessible from the NRC Web site at http://www.nrc.gov/reading-rm.html (the Public Electronic Reading Room).
2 J. Shea This letter does not contain new or amended information collection requirements subject to the Paperwork Reduction Act of 1995 (44 U.S.C. 3501 et seq). Existing information collection requirements were approved by the Office of Management and Budget, under control number 3150-0011, 3150-0014, 3150-0044, and 3150-0135. The NRC may not conduct or sponsor, and a person is not required to respond to, a request for information or an information collection requirement unless the requesting document displays a currently valid Office of Management and Budget control number.
Sincerely,

50-390 Inspection Dates:
July 22-26, 2013 and August 12-16, 2013 Procedures:

Note that the inspectors cannot accept data provided on USB or flash drives due to NRC IT security policies. An index to the contents is also helpful. For those items requesting a list of documents/areas, the inspectors will select documents/areas from the list for onsite review. If any of the requested information is too burdensome to provide electronically, simply indicate that the requested material is available for onsite review by the inspectors. Experience has shown that a well organized CD leads to a more efficient inspection, and lessens additional burden on licensee staff. During the inspection, the inspectors may request additional documents. If the licensee wishes to use an electronic document service such as CERTRAC or a Shareware portal, the inspectors will try to accommodate for the documentation requested onsite. The initial documents should not require an internet connection to be reviewed.
Documentation is requested from the dates identified in each inspection area, to the present.
For IP 71151 documentation is requested from July 1, 2012, to present.
