CATAWBA NUCLEAR STATION - NOTIFICATION OF NRC SUPPLEMENTAL INSPECTION (95001) AND REQUEST FOR INFORMATION
Dear Nicole Flippin:
By letter dated September 5, 2024 (ADAMS ML24234A291), the U.S. Nuclear Regulatory Commission (NRC) communicated to Duke Energy the final significance determination of a finding having low-to-moderate safety significance (White) at Catawba Nuclear Station, Unit 2.
The finding was associated with a failure to maintain the functionality of the emergency ventilation system which resulted in 2A emergency diesel generator inoperability.
On February 21, 2025; Kevin Ellis, General Manager of Regulatory Affairs, Policy, and Emergency Preparedness; notified Robert Williams, Chief, Projects Branch 1; of Duke Energys readiness for the NRC to conduct a supplemental inspection to review the actions taken to address the White finding. Accordingly, the NRC plans to conduct a supplemental inspection, beginning on March 10, 2025, at Catawba Nuclear Station, Unit 2 using Inspection Procedure 95001, Supplemental Inspection Response to Action Matrix Column 2 (Regulatory Response)
Inputs. This on-site inspection is scheduled to be performed March 10 through March 14, 2025.
In order to minimize the impact to your on-site resources and to ensure a productive inspection for both organizations, we have enclosed a request for documents needed for this inspection. It is important that all of the documents are up-to-date and complete in order to minimize the number of additional documents requested during the on-site portion of the inspection. To the extent possible, please organize the information as specified in the Request for Information.
Experience has shown that poorly organized files can lead to a less efficient inspection and places additional burden on licensee staff. Secure file server access such as Certrec or SharePoint is preferred. During the inspection, the inspectors may request additional documents. If there are questions regarding the documents or material requested, or if the documents cannot be provided by the due date, please do not hesitate to contact the lead inspector, Jamin Seat, at (404) 997-4475. We have discussed the schedule for these inspection activities with your staff and understand that our regulatory contact for this inspection will be Ms.
Sherry Andrews of your organization.
