Grand Gulf Nuclear Station, Unit 1, began the inspection period at 100 percent rated thermal power (RTP). On October 3, 2025, operators reduced power to 60 percent RTP for a control rod sequence exchange, control rod testing, and turbine stop and control valve testing. During the subsequent power ascension on October 4, 2025, an issue with the reactor recirculation pump B hydraulic power unit prevented a return to full RTP. The unit remained at approximately 91 percent RTP until repairs were completed. The repairs were followed by a return to 100 percent RTP on October 7, 2025. On October 27, 2025, operators reduced power to approximately 97 percent RTP due to electrohydraulic control fluid leakage associated with the turbine stop and control valves. A control rod pattern adjustment began on November 9, 2025, resulting in a reduction to 80 percent RTP. The unit returned to 100 percent RTP on November 10, 2025. On November 14, 2025, operators reduced power to 50 percent RTP to conduct a steam jet air ejector swap followed by a subsequent return to 100 percent RTP the same day. On December 5, 2025, the station performed a rod pattern adjustment and reduced power to 76 percent RTP with a subsequent return to 100 percent RTP later that day, where the unit remained at or near for the remainder of the inspection period.

PLANT STATUS

Grand Gulf Nuclear Station, Unit 1, began the inspection period at 100 percent rated thermal power (RTP). On October 3, 2025, operators reduced power to 60 percent RTP for a control rod sequence exchange, control rod testing, and turbine stop and control valve testing. During the subsequent power ascension on October 4, 2025, an issue with the reactor recirculation pump B hydraulic power unit prevented a return to full RTP. The unit remained at approximately 91 percent RTP until repairs were completed. The repairs were followed by a return to 100 percent RTP on October 7, 2025. On October 27, 2025, operators reduced power to approximately 97 percent RTP due to electrohydraulic control fluid leakage associated with the turbine stop and control valves. A control rod pattern adjustment began on November 9, 2025, resulting in a reduction to 80 percent RTP. The unit returned to 100 percent RTP on November 10, 2025. On November 14, 2025, operators reduced power to 50 percent RTP to conduct a steam jet air ejector swap followed by a subsequent return to 100 percent RTP the same day. On December 5, 2025, the station performed a rod pattern adjustment and reduced power to 76 percent RTP with a subsequent return to 100 percent RTP later that day, where the unit remained at or near for the remainder of the inspection period.

INSPECTION RESULTS

Licensee-Identified Non-Cited Violation 71111.15 This violation of very low safety significance was identified by the licensee and has been entered into the licensee corrective action program and is being treated as a non-cited violation, consistent with Section 2.3.2 of the Enforcement Policy.

Violation: Technical Specification 3.6.4.3 requires, in part, two standby gas treatment (SBGT)subsystems to be operable during MODE 1. Condition A.1 of TS 3.6.4.3 specifies that with one subsystem inoperable, the inoperable subsystem shall be returned to operable status within 7 days. Additionally, TS LCO 3.6.4.3, Condition B.1 specifies, in part, that if the required action and associated completion time of Condition A is not met, the licensee shall be in MODE 3 within 12 hours1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br />.

Contrary to the above, from June 28 to July 14, 2025, one SBGT subsystem was inoperable during MODE 1, the subsystem was not returned to operable status within 7 days in accordance with Condition A.1 of TS 3.6.4.3, the required action and associated completion time of Condition A was not met, and the licensee was not in MODE 3 within 12 hours1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br />.

Specifically, operators noted that the system flow recorder for SBGT subsystem B was reading 3400 cubic feet per minute while the system was in standby, which indicated an instrumentation deficiency that would have prevented proper automatic operation of system flow control vanes. The flow instrumentation began reading inaccurately on June 21, 2025, at 4:16 a.m., at which point the system became inoperable. With one SBGT subsystem inoperable for 23.36 days, the licensee failed to return it to operable status within 7 days or be in MODE 3 within 12 hours1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br /> at 4:16 p.m. on June 28, 2025.

Significance/Severity: Green. The failure to identify the inoperable SBGT subsystem prior to exceeding the allowed outage time is more than minor because it adversely affected the SSC and Barrier Performance attribute of the Barrier Integrity cornerstone objective to provide reasonable assurance that physical design barriers (fuel cladding, reactor coolant system, and containment) protect the public from radionuclide releases caused by accidents or events. The inspectors assessed the significance of the finding using IMC 0609, Appendix A, The Significance Determination Process for Findings At-Power, Exhibit 3, Barrier Integrity Screening Questions. The inspectors determined the finding only represented a degradation of the radiological barrier function provided by the SBGT system. Therefore, the issue screened to Green.

The disposition of this violation closes LER 05000416/2025-004-00, Standby Gas Treatment System Train Inoperable Which Led to a Failure to Identify Condition Prohibited by Technical Specifications.

Corrective Action References: CR-GGN-2025-03091 Observation: Semiannual Trend Review 71152S For the inspection period, the inspectors noted 26 condition reports concerning plant emergency lights. Of the 26 condition reports, 13 concerned lights as required per 10 CFR Part 50 Appendix R, Section III.J. Emergency lighting required by Appendix R is required, in part, to provide emergency lighting in all areas needed for safe operation of safe shutdown equipment and in access and egress to routes thereto. While the inspectors did not identify any performance deficiencies related to emergency lighting, the inspectors observed that 5 of 13 Appendix R emergency light condition reports involved battery replacement. Of the 13 condition reports, three of those reports led to replacement of the battery charging circuit boards. The licensee provided the emergency lighting vendor manual to the inspectors, which describes proper operation of the emergency lights. The emergency lights have three charging modes: a fast-charging mode, an equalizing mode, and a trickle charging mode. During normal operation the charger may enter fast charging, equalize, and then return to trickle charging. Inspectors noted emergency lights are frequently in fast charging. Per the vendor manual, an emergency light that stays in fast charging mode could indicate issues with the battery or the battery charging circuitry. No findings or violations were identified.

EXIT MEETINGS AND DEBRIEFS

The inspectors verified no proprietary information was retained or documented in this report.

  • On January 12, 2026, the inspectors presented the integrated inspection results to Brad Kapellas, Site Vice President, and other members of the licensee staff.
