Watts Bar Nuclear Plant Radiation Safety Baseline Inspection Initial Information Request Inspection Report: 2025002 During the weeks of April 14 - 18 and April 28 - May 2, 2025, the NRC will perform a baseline Radiation Safety Inspection at the Watts Bar Nuclear Plant (NRC Inspection Procedures 71124.01, 71124.03, 71124.04, 71124.05, and 71151).

Experience has shown that this inspection is resource-intensive for both the NRC inspectors and your staff. In order to minimize the impact to your onsite resources and to ensure a productive inspection, we are requesting in advance documents needed for this activity. 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 NRC requests that these documents be provided to the inspectors no later than April 4, 2025.

If there are any questions about this inspection or the material requested, please contact the lead inspector, Adam Nielsen at 404-997-4660, or the Radiation Safety Branch (RSB) Chief, Katie McCurry at 404-997-4438.

In accordance with Title 10 of the Code of Federal Regulations (10 CFR) 2.390, Public inspections, exemptions, requests for withholding, a copy of this document will be available electronically for public inspection in the NRC Public Document Room, or from the Publicly Available Records component of NRC's Agencywide Documents Access and Management System (ADAMS); accessible from the NRC Web site at http://www.nrc.gov/reading-rm/adams.html.
