Additional Tracking Items

Type Issue Number Title Report Section Status LER 05000397/2024-001-00 Failure to Track Operability 71153 Closed Requirements of Transversing In-Core Probe Valves

PLANT STATUS

The unit began the inspection period at rated thermal power. On May 1, 2024, the unit was down powered to 32 percent for repair of the adjustable speed drive system for reactor recirculation pump A. The unit was returned to rated thermal power on May 2, 2024. The unit was down powered on June 9, 2024, for preventive maintenance on the reactor recirculation pump adjustable speed drive system. The station was restored to rated thermal power on June 11, 2024, and remained at or near to rated thermal power for the remainder of the inspection period.

INSPECTION SCOPES

Inspections were conducted using the appropriate portions of the inspection procedures (IPs) in effect at the beginning of the inspection unless otherwise noted. Currently approved IPs with their attached revision histories are located on the public website at http://www.nrc.gov/reading-rm/doc-collections/insp-manual/inspection-procedure/index.html. Samples were declared complete when the IP requirements most appropriate to the inspection activity were met consistent with Inspection Manual Chapter (IMC) 2515, Light-Water Reactor Inspection Program - Operations Phase. The inspectors performed activities described in IMC 2515, Appendix D, Plant Status, observed risk significant activities, and completed on-site portions of IPs. The inspectors reviewed selected procedures and records, observed activities, and interviewed personnel to assess licensee performance and compliance with Commission rules and regulations, license conditions, site procedures, and standards.

71114.01 - Exercise Evaluation

Inspection Review (IP Section 02.01-02.11) (1 Sample)

(1) The inspectors evaluated the biennial emergency plan exercise conducted on March 26, 2024. The exercise scenario simulated a partial loss of offsite power as a main turbine generator trip. Losses of emergency diesel generators resulted in only one source of alternating current power being available onsite. This was followed by a simulated steam line break in the reactor core isolation cooling system, which resulted in a simulated radiological release offsite. This was complicated further with the inability to restore reactor pressure vessel water level above the top of active fuel, coupled with filtration failures in the standby gas treatment system.

The licensee completed its critique process for the exercise on April 9, 2024, and the inspectors subsequently evaluated the effectiveness of the critique process to identify performance weaknesses and deficiencies to ensure they were entered into the corrective action program for resolution.

This documents completion of this inspection sample which was documented as a partial sample in Inspection Report 05000397/2024001 (Agencywide Documents Access and Management System [ADAMS] Accession No. ML24115A189).

INSPECTION RESULTS

Minor Violation 71111.15 Failure to Isolate Primary Containment Isolation Valve

Minor Violation: The inspectors identified a self-revealing, minor violation of TS 3.6.1.3 for primary containment isolation valves (PCIVs) TIP V-1 and V-2. Specifically, on November 16, 2023, clearance order D-TIP-V-7 and V-8 -001 was hung to support replacement of squib valves TIP-V-7 and TIP-V-8, which was an administrative control to close and de-activate TIP-V-1 and TIP-V-2 and provide means to satisfy TS Action Statements 3.6.1.3.A.1 and 2. At 10:43 a.m. on November 21, 2023, clearance orders D-TIP-V-7 and 8-001 were lifted prior to completing all of the post-maintenance testing (PMT) and caused TIP-V-1 and TIP-V-2 to be tracked as inoperable on an limiting condition of operability (LCO) Tracking Sheet T23-TIP-V-7 and no longer served as administrative means to satisfy TS action statements A.1 and A.2. On November 22, 2023, the on-coming shift control room supervisor (CRS) reviewed the LCO Tracking Sheet and identified that the PMT requirements were not completed and immediately directed crew to perform the remaining PMT to restore Operability. TS action statement was exited at 9:21 a.m. with TS A.1 and A.2 being ineffectively tracked for 22 hours2.546296e-4 days <br />0.00611 hours <br />3.637566e-5 weeks <br />8.371e-6 months <br /> and 38 minutes.

Screening: The inspectors determined the performance deficiency was minor. TIP-V-1 and 2 remained closed and de-activated despite not being administratively controlled by the clearance order D-TIP-V-7 and 8-001; therefore, although it is associated with the Barrier integrity cornerstone, this event did not represent a pathway out of containment. It also could not be viewed as a precursor to a significant event since TIP-V-1 and 2 remained closed and de-energized despite no longer being tagged out. Successful completion of the PMT demonstrated there was no potential to lead to a more significant safety concern and did not adversely affect an associated cornerstone objective outside of administrative tracking; therefore, this issue screens to minor.

Enforcement:

TS 3.6.1.3, "Primary Containment Isolation Valves (PCIVs)," requires, in part, that each PCIV shall be operable in Modes 1, 2, and 3. TS 3.6.1.3, condition A, states, in part, if one or more penetration flow paths with one PCIV inoperable, then isolate the affected penetration flow path by use of at least one closed and de-activated automatic valve in 4 hours4.62963e-5 days <br />0.00111 hours <br />6.613757e-6 weeks <br />1.522e-6 months <br />. TS 3.6.1.3, condition E, states, in part, that if the required action and associated completion time of condition A is not met, then be in Mode 3 in 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 November 21-22 (22 hours2.546296e-4 days <br />0.00611 hours <br />3.637566e-5 weeks <br />8.371e-6 months <br /> and 3 minutes), with one PCIV inoperable, the affected penetration flow path did not use at least one de-activated automatic valve and action was not taken to place Columbia Generating Station in Mode 3 within 12 hours1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br /> as required by TS 3.6.1.3.E.1. Specifically, the licensee lifted the clearance order D-TIP-V-7 and 8-001 prior to completing PMT and restoring TIP-V-1 and 2 to an operable condition. The licensee's immediate corrective actions to perform PMT OSP-TIP-M101 restored operability to TIP-V-1 & 2.

The disposition of this violation closes LER 05000397/2024-001-00, Failure to Track Operability Requirements of Transversing In-Core Probe Valves. This failure to comply with TS 3.6.1.3 constitutes a minor violation that is not subject to enforcement action in accordance with the NRC's Enforcement Policy.
