The inspectors reviewed the licensees corrective action program that might be indicative of a more significant safety issue and identified a potential trend in NRC-identified issues related to PM task detail and completion.
INSPECTION RESULTS Minor Violation 71152A Failure to Perform Engineering Change Evaluation Minor Violation: In 2013, AREVA recommended and performed changes to the Cutler Hammer Type DHP-VR 4.16kV breakers that they provided to the licensee. However, the inspectors identified the licensee did not take subsequent actions required by their procedures. Specifically, the licensee failed to perform an engineering change evaluation in accordance with MFP-QA-1220, Engineering Change Process Handbook, to ensure that the design changes were acceptable for Susquehanna design requirements.
The licensee documented the issue in CR-2024-14984 and initiated actions to perform an evaluation to validate that the changes to the DHP-VR 4.16kV breakers met the design requirements.
Screening: The inspectors determined the performance deficiency was minor because it did not adversely affect the Mitigating Systems cornerstone objective. Specifically, the failure to evaluate changes to the design of Cutler Hammer Type DHP-VR 4.16kV circuit breakers had little or no safety impact, as the subsequently completed engineering change evaluation determined that the changes would meet design requirements.
Enforcement: 10 CFR Part 50, Appendix B, Criterion III, requires that measures shall be established to assure that design changes, including field changes, shall be subject to design control measures commensurate with those applied to the original design and be approved by the organization that performed the original design unless the applicant designates another responsible organization.
Contrary to this requirement, the licensee did not subject vendor design changes to design control measures commensurate with those applied to the original design. Specifically, the licensee failed to perform an engineering change evaluation in accordance with MFP-QA-1220, Engineering Change Process Handbook, to ensure that the design changes were acceptable for Susquehanna design requirements.
The licensee has taken actions to restore compliance by performing the missed engineering change evaluation. This failure to comply with 10 CFR Part 50, Appendix B, Criterion III, Design Control, constitutes a minor violation that is not subject to enforcement action in accordance with the NRCs Enforcement Policy.
10 Observation: Emergency Service Water Piping Degradation 71152A The inspectors reviewed the licensee's evaluations and corrective actions associated with the ESW piping wall thinning and/or pinhole leaks to standards in their corrective action program procedures and American Society of Mechanical Engineers Code Case N-513 which was approved for use. On a sampling basis, the inspectors verified that the licensee measured piping wall thickness to ensure structural integrity of the pipe and performed additional exams at other susceptible locations as required by the code case. The inspectors verified corrective actions were completed to replace the pipe or continue monitoring. The inspectors did not identify any findings or violations of more than minor significance.
Observation: Motor Operated Valve Long Life Grease Did Not Meet Acceptance Criteria 71152A The inspectors reviewed the licensees evaluation and corrective actions to address MOV Long Life grease that did not meet acceptance criteria during commercial grade dedication as documented in CR-2024-20372. The grease was found at the minimum specification for weld point. The inspectors found the licensee credited their MOV monitoring program to identify impacts. The program included grease sampling and analysis every 2 years on active safety-related MOVs. The inspectors found that the licensee also contacted the grease manufacturer to affirm product composition and revised their dedication process to include the acceptance criteria range. The inspectors further independently reviewed a sample of MOV test results and did not identify performance issues since grease application. The inspectors did not identify any findings or violations of more than minor significance.
Observation: Corrective Actions for Failure to Adequately Control Transient Combustibles in Units 1 and 2 Turbine Building 71152A The inspectors reviewed CRs that documented two separate occurrences in which combustible loading permit limits were exceeded. The permits allowed for a specific number of lube oil barrels to be stored in the Units 1 and 2 lube oil conditioner rooms. For each of these instances, the licensee immediately took action to reduce the amount of combustibles located within the rooms in order to comply with their long standing combustible loading permits. The inspectors noted that the licensee has developed an action request to add additional signage in each room to help make work groups aware of the limitations for storing transient combustibles in the area. The inspectors did not identify any findings or violations of more than minor significance.
Observation: Corrective Actions for 4 Kilovolt Breaker Charging Motor Failure 71152A The inspectors reviewed CR-2024-00769 which documented a 4kV breaker removed from 1A20405 that failed as found testing. On January 9, 2024, the licensee identified an issue with the charging motor associated with the Unit 1 D core spray pump breaker during a system outage window where the charging motor would function, but it was unable to properly charge the closing springs. Further investigation identified that a gear, noted as the ratchet wheel, was not making sufficient contact with its counterpart which resulted in the charging motor being unable to perform its intended function. The licensee replaced the breaker with a spare breaker and then shipped the defective breaker to the vendor (Framatome/AREVA) for overhaul and refurbishment.
The inspectors reviewed the CR, actions created in response to the CR, the failure analysis, work orders associated with the failure analysis, and conducted interviews with site Engineering staff. The inspectors noted that the licensee has a replacement strategy in place to replace all the Cutler Hammer Type DHP-VR 4.16kV circuit breakers which will include
11 newer style ratchet wheels that will have improved engagement. The inspectors also noted that the licensee enhanced their maintenance procedures to inspect the ratchet wheels periodically. The inspectors did not identify any findings or violations of more than minor significance.
Observation: Semiannual Trend 71152S The inspectors' semiannual trend review performed in accordance with IP 71152, Problem Identification and Resolution, noted a trend in NRC-identified issues related to PM task detail and completion. The inspectors identified the following examples which illustrate vulnerabilities.
The inspectors identified that the Unit 1 containment instrument gas system nitrogen cylinders exceeded their hydrostatic testing requirement. The containment instrument gas nitrogen serves as the motive force to operate the automatic depressurization valves system in the event of a station blackout. Hydrostatic testing is required every 10 years. The PM task to replace the cylinders was scheduled for completion in August 2023. CR-2023-12374 was generated when the first set of replacement cylinders did not meet the purchasing specification. The purchasing specification requires that new cylinders must complete a hydrostatic test within 6 months of delivery. The bottles received in 2023 had been tested more than 6 months earlier. This CR was closed without replacement nitrogen cylinders being installed. A second replacement was attempted in March 2024, and the second set of replacement cylinders had dimensional differences from the installed cylinders requiring an engineering change to be implemented for installation. The station identified that the same condition was present in Unit 2. The station reduced the PM frequency to 9 years ensuring that the cylinders would be replaced prior to exceeding hydrostatic testing frequency. The inspectors noted the installed gas cylinders did not exhibit a degrading trend in gas pressure.
This issue was captured in CR-2024-16145.
The inspectors identified that there were no PM tasks to verify the condition of staged hoses for the standby liquid control system. These hoses are used to inject a boron solution into the core using the steam driven reactor core isolation cooling pump during a station blackout to add negative reactivity to the core. PM Task S4003-51 requires a quarterly verification that the hose reel is available for deployment and the exposed hose is acceptable. These hoses are approximately 300 feet long and are wound around their holders multiple times. The visible, exposed hose is a fraction of the full hose. The hoses had last been unrolled in the early 2000s. The hoses for both units were subsequently unrolled, pressure tested, and found to be acceptable. The station is determining the appropriate long-term testing or replacement frequency and captured the issue in CR-2024-12099.
The inspectors identified permanent lead shielding blankets were inadequately secured to piping to the radiation waste system piping. The inspectors identified six blankets without adequate banding in November 2024. The suppression pool filter pump, suppression pool filter pump inboard, and outboard isolation valves were below three of the inadequately secured shielding blankets. These components could have been damaged if the shielding became dislodged during a seismic event. These blankets are verified annually per PM task L0000-21. This task requires compliance to be verified against NDAP-QA-0404, Shielding Installation and Removal. NDAP-QA-0404, Attachment E, Approved Banding Mechanisms
12 for Direct Shielding, contains the required approved banding. This PM task was completed in September 2024. This issue was captured in CR-2024-15905 and the banding was corrected.
The PM task was updated to include banding verification.
These examples share the common theme of PM task implementation. The examples cover a wide variety of PM issues including scheduling, implementation, and scope. The inspectors did not identify any findings or violations of more than minor significance.
