List of Findings and Violations

No findings or violations of more than minor significance were identified.

Additional Tracking Items

None.

PLANT STATUS

Unit 2 began the inspection period at rated thermal power. On April 19, 2023, the unit was down powered to 26 percent due to a sudden electro-hydraulic control (EHC) fluid leak from the actuator seal associated with the turbine right main steam stop valve MS-314. Following repairs to MS-314, the unit was returned to rated thermal power on April 21, 2023. On June 22, 2023, an automatic turbine trip followed by reactor trip occurred during reactor trip breaker (RTB) and reactor protection system logic testing due to the malfunction of an RTB position indication switch. Following RTB repairs, the unit was restarted on June 24, 2023, and returned to rated thermal power on June 25, 2023. The unit remained at or near 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.

INSPECTION RESULTS

Minor Violation 71152S Minor Violation: Robinson Unit 2 Technical Specification (TS) 5.4.1, Procedures, requires, in part, that procedures be established and implemented as recommended in Regulatory Guide 1.33, Quality Assurance Program Requirements, Revision 2, Appendix A, 1978. This includes the plant fire protection program, as specified in Section 1.l of Appendix A. Robinson fire protection program implementing procedures AD-FP-ALL-1520, Transient Combustible Control, and AD-FP-ALL-1551, Fire Protection Impairments, provide the plant fire protection programmatic requirements for controlling transient combustible materials and for documenting/tracking fire impairments.

Contrary to the above, between April 2023 to May 2023, the inspectors identified the following five examples associated with this minor violation in which the licensee failed to implement adequate fire protection transient combustible control or fire impairment tracking requirements in accordance with AD-FP-ALL-1520 and AD-FP-ALL-1551:

On April 19, 2023, the inspectors identified a 55-gallon drum container about 75 percent full of transient combustible waste materials in the turbine building tool room area fitted with an Underwriters Laboratories (UL) rated self-closing fire lid that was non-functional. Due to the looseness of the installed fire lid to the drum, it was incapable of closing to mitigate a fire if initiated in the container. The inspectors determined this condition was contrary to AD-FP-ALL-1520, which required that waste containers fitted with self-closing UL rated fire lids be maintained in accordance with the manufacturers installation instructions to ensure proper operation. Once identified to the licensee, the problem was immediately corrected. Subsequently, the fire lid installation instructions were re-emphasized with radiation protection workers responsible for maintaining the work area.

On May 8, 2023, during a plant tour of the unit 2 cable spreading room, the inspectors identified previous work-related transient combustible waste materials (e.g., small scraps of paper, used pieces of electrical tape and caution tape, small post-it notes, ty-wraps, plastic caps, etc.) in the rooms subfloor area under several of the electrical panels. The inspectors determined this was contrary to AD-FP-ALL-1520, which required that work-related waste, debris, or other combustibles, be removed from the power block work locations upon completion of the work. Once identified to the licensee, a more extensive search and retrieval of the subfloor area was conducted to remove any combustible waste materials. Subsequently, a site wide news message was sent out to discuss the issue and reinforce the need for personnel to adhere to proper transient combustible and housekeeping practices.

On May 22, 2023, during a plant tour of the turbine buildings chemical feed room, the inspectors identified a waste container fitted with a UL rated self-closing fire lid that was overfilled beyond its rated capacity and the lid was propped open and caught against a wall I-Beam preventing it from closing. The inspectors determined this condition was contrary to AD-FP-ALL-1520, which required waste containers with UL rated self-closing lids be maintained and operated in compliance with the UL listing to ensure its functionality. Once identified to the licensee, the container was emptied and moved away from the wall obstruction that was preventing it from closing.

On May 23, 2023, the inspectors reviewed the licensees fire protection controls implemented during a 2-year preventive maintenance outage on the B EDG. During this maintenance activity, the licensee implemented two planned fire impairments to support the work. One impairment was for de-activating the B EDG room carbon dioxide (CO2) fire suppression system and the second to allow the room exterior door to remain propped open for the duration of the maintenance. The inspectors identified that while a fire impairment tracking entry was created for the impaired CO2 system, a tracking entry was not established for the B EDG door being propped open. The inspectors determined this was contrary to AD-FP-ALL-1551, which required all fire impairments to be documented in the licensees impairment tracking system. Once identified to the licensee, the licensee formally entered the fire door into the tracking system as required.

On May 24, 2023, during the same B EDG maintenance activity described above, the inspectors noted there was a significant amount of work-related transient combustible materials introduced into the B EDG room and just outside the room. This material included bulk quantities of cardboard, oil absorbent pads/rags, paper products, rolled up plastic tubing and rubber hoses, flammable cleaning aerosols, trash, etc. The inspectors identified one instance where all workers left the area for short period (~ 1-hour) for a lunch break. The inspectors determined this was contrary to AD-FP-ALL-1520, which required a work location with this amount and type of added transient combustibles, to be in continuous attendance or a transient combustible permit obtained with a continuous fire watch established. Once identified to the licensee, maintenance personnel were immediately re-directed not to leave the area unattended and coached on the applicable transient combustible control requirements. The licensees subsequent investigation determined that this was the only instance where the area was left unattended during this maintenance activity.

The licensee entered these issues into the corrective action program as NCRs 2473607, 2473800, and 2473926.

Screening: The inspectors determined the performance deficiency was minor. Specifically, the performance deficiency was not a precursor to a significant event, would not have led to a more significant safety concern if left uncorrected, and did not adversely affect the initiating events cornerstone objectives either due to the lack of a credible fire ignition source, lack of proximity to important plant safety equipment, existence of functional fire detection/suppression systems, or since the fire protection strategies for the affected areas and fire zones remained sufficient even with the fire protection discrepancies.

Enforcement:

This failure to comply with the provisions of TS 5.4.1.a constitutes a minor violation that is not subject to enforcement action in accordance with the NRCs Enforcement Policy.

Observation: Semi-Annual Trend Review of Fire Protection Program 71152S The inspectors reviewed the licensees corrective action program, which included inspector-identified issues, between the period of January 2023 to June 2023, for potential adverse trends in the implementation of the Robinson fire protection program that might be indicative of a more significant safety issue. The inspectors identified an adverse trend in the licensees control of transient combustible materials as a result of identifying multiple examples over a short period, where personnel failed to follow the requirements of procedure AD-FP-ALL-1520, Transient Combustible Control. These issues are documented in the Minor Violation results section of this report. The inspectors considered it noteworthy that all the issues were NRC-identified and there were not any similar licensee-identified transient combustible issues that were found during the inspectors search of the licensees corrective action program during this six-month period of review. The following NCRs associated with the identified issues are referenced in the Minor Violation results section of this report: NCRs 2473607, 2473800, and 2473926. The inspectors noted that the licensees corrective actions for these items included the immediate correction of the identified discrepancies, as well as disseminating a site wide news message to discuss the more significant issues and reinforce the need for personnel to be more sensitive to adhering to proper transient combustible and housekeeping practices. However, a more detailed investigation by the licensee into the underlying causes of the issues had not been conducted. The licensee acknowledged the adverse trend and entered it into their corrective action program as NCR
