By letter dated November 21, 2024, the U.S. Nuclear Regulatory Commission (NRC) communicated to you the agencys intent to perform a supplemental inspection to review your evaluation of the root and contributing cause(s) and corrective actions for the White finding at your Browns Ferry Nuclear Plant, Unit 2.

On January 15, 2025, your staff notified the NRC of your readiness for the agency to conduct a supplemental inspection. Therefore, the NRC plans to conduct a supplemental inspection in accordance with Inspection Procedure 95001, Supplemental Inspection Response to Action Matrix Column 2 (Regulatory Response) Inputs, beginning on February 10, 2025. This inspection procedure is conducted to provide assurance that the root and contributing causes for the performance issues are understood, and to provide assurance that the corrective actions are sufficient to address the root and contributing causes and prevent recurrence.

To minimize the impact on your staff and to ensure a productive inspection, we have enclosed a request for information needed prior to the inspection preparation week. These documents identified are those that the inspectors will need prior to arrival at the plant. 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 inspection. If possible, we would request that this information be provided electronically to the inspectors. Please provide the information requested in the Enclosure to the Region II Office or a file sharing site by February 3, 2025. Additional documents may be requested during the preparation week. The inspectors will try to minimize your administrative burden by specifically identifying only those documents required for inspection preparation.

Prior to arriving onsite, Mr. Towne will discuss the following inspection support administrative details: (1) availability of knowledgeable plant engineering and licensing personnel to serve as points of contact during the inspection, (2) method of tracking inspector requests during the inspection, (3) computer access, (4) working space, (5) arrangements for site access, and (6) other applicable information. We have discussed the schedule for the inspection with your staff and understand that our regulatory contact for this inspection will be Baruch Calkin of your organization. If there are any questions regarding our schedule for the inspection or the material requested, please contact Mr. Brian Towne at 630-829-9543 or electronically at brian.towne@nrc.gov.

Logistics:

Please schedule an entrance meeting for around 2:00 PM. on Monday, February 10, 2025 (approximately 15 minutes). The date and time of the exit meeting will be discussed at a later date. In addition, I would like to have a daily debrief with your inspection support staff at a convenient time in the afternoons of the onsite inspection week (approximately 30 minutes).

We intend to use the NRC Resident Inspector Office conference room as workspace for the inspectors. We will also need an area available for conducting interviews.
