SUBJECT:
COOPER NUCLEAR STATION - CYBER SECURITY INSPECTION REPORT 05000298/2025401
Dear Khalil Dia:
On September 19, 2025, the U.S. Nuclear Regulatory Commission (NRC) completed an inspection at Cooper Nuclear Station. On September 24, 2025, the NRC inspectors discussed the results of this inspection with Bill Chapin, GMPO, General Manager of Plant Operations and other members of your staff. The results of this inspection are documented in the enclosed report.
Due to the temporary cessation of government operations, which commenced on October 1, 2025, the NRC began operating under its Office of Management and Budget approved plan for operations during a lapse in appropriations. Consistent with that plan, the NRC operated at reduced staffing levels throughout the duration of the shutdown. However, the NRC continued to perform critical health and safety functions and make progress on other high priority activities associated with the ADVANCE Act and Executive Order 14300. On November 13, 2025, following the passage of a continuing resolution, the NRC resumed normal operations. However, due to the 43-day lapse in normal operations, the Office of Nuclear Reactor Regulation granted the Regional Offices an extension on the issuance of inspection reports that could not be issued within 45 days after the end of the inspection because of the shutdown.
Three findings of very low security significance (Green) are documented in this report. Three of these findings involved violations of NRC requirements. We are treating these violations as non-cited violations (NCVs) consistent with Section 2.3.2 of the Enforcement Policy.
If you contest the violations or the significance or severity of the violations documented in this inspection report, you should provide a response within 30 days of the date of this inspection report, with the basis for your denial, to the U.S. Nuclear Regulatory Commission, ATTN:
Document Control Desk, Washington, DC 20555-0001; with copies to the Regional Administrator, Region IV; the Director, Office of Enforcement; the Director, Office of Nuclear Security and Incident Response; and the NRC Resident Inspector at Cooper Nuclear Station. The following cross cutting aspects were assigned to findings using Inspection Manual Chapter 0310 Aspects Within Cross Cutting Areas: one [H.7] - Documentation and one [H.9] - Training.
If you disagree with a cross-cutting aspect assignment in this report, you should provide a response within 30 days of the date of this inspection report, with the basis for your disagreement, to the U.S. Nuclear Regulatory Commission, ATTN: Document Control Desk, Washington, DC 20555-0001; with copies to the Regional Administrator, Region IV; the Director, Office of Nuclear Security and Incident Response; and the NRC Resident Inspector at Cooper Nuclear Station.
