EXECUTIVE SUMMARY

Connecticut Atomic Power Company

Inspection Report Nos. 07200039/2024001 and 05000213/2024001

A routine, announced inspection was completed at Connecticut Yankee Atomic Power Company (Connecticut Yankee) on August 2, 2024. On-site inspection activities were performed from July 22, 2024, to July 24, 2024. The inspection included a review of radiation protection, fire protection, emergency preparedness, surveillance, maintenance, environmental monitoring, training, quality assurance, corrective action programs, and aging management activities. The inspection consisted of observations on-site activities by the inspector, interviews with Connecticut Yankee personnel, a review of procedures and records, and ISFSI pad walkdowns. The NRCs program for overseeing the safe operation of an ISFSI is described in Inspection Manual Chapter (IMC) 2690, Inspection Program for Storage of Spent Reactor Fuel and Reactor-Related Greater-Than-Class C Waste at Independent Spent Fuel Storage Installations and for 10 CFR Part 71 Transportation Packagings.

Based on the results of this inspection, no violations of more than minor safety significance were identified.

REPORT DETAILS

1. Inspection Scope, Observations, and Conclusion

a. Inspection Scope

The inspector assessed whether Connecticut Yankee personnel had operated and maintained ISFSI programs at an Away-From-Reactor (AFR) ISFSI in conformance with the commitments and requirements contained in the Final Safety Analysis Report (FSAR), Safety Evaluation Report (SER), Certificate of Compliance (CoC), Technical Specifications (TS), Quality Assurance (QA)program, Connecticut Yankee procedures, and 10 CFR Part 72.

AFR ISFSI activities, located at sites where loading operations have been completed, are essentially passive operating facilities. The inspectors review was directed toward evaluating the ongoing adequacy of the radiation protection, material conditions, fire protection, emergency preparedness, surveillance, maintenance, environmental monitoring, training, QA, and corrective action programs.

The inspector observed aging management activities, interviewed site personnel, and reviewed procedures and records. The inspector also reviewed changes made to Connecticut Yankees programs and procedures since the last inspection to determine if changes were consistent with the license or CoC and if such changes reduced the effectiveness of the program.

b. Observations and Findings

The inspector determined that Connecticut Yankees plans and preparations for controlling radiological activities were effective in meeting 10 CFR Part 20 requirements. The inspectors also verified that Special Nuclear Material (SNM)stored at the ISFSI was properly accounted for. A review of dosimetry records and environmental reports were found to be complete, and all employee exposures were below the regulatory dose limits. In addition, dose to members of the public at the nearest accessible location to the ISFSI were within limits as prescribed by10 CFR 72.104.

The inspector verified that Connecticut Yankees emergency preparedness program was properly coordinated with the appropriate offsite support groups, agencies, and Local Law Enforcement Agencies (LLEAs). The inspector also verified the emergency call list was current and checked periodically for accuracy and all revisions to the emergency plan had been submitted to the NRC and reviewed by the Office of Nuclear Security and Incident Response (NSIR).

The inspector verified that daily temperature monitoring of the Vertical Concrete Casks (VCCs) was performed by site personnel in accordance with surveillance requirements in the TS and that Connecticut Yankees procedures contained back up plans if the primary surveillance method became unavailable. The inspector also verified that transient combustibles had not been stored on the ISFSI pad or in the vicinity of the VCCs and confirmed procedures were in place to control entry onto the ISFSI pad.

The inspector performed an independent walkdown survey of the VCC inlet vents to verify dose rates.

The inspector reviewed and determined that Connecticut Yankee had a training program which consisted of classroom instruction, on-the-job training, and various drills. Additionally, the training program includes shift turnover briefings by supervisors and that refresher training was provided on a regular frequency.

The inspector verified all employees had been trained and qualified to perform their assigned ISFSI related duties in accordance with the requirements.

The inspector determined that issues were entered into the corrective action program, prioritized, and evaluated commensurate with their safety significance, and corrective actions were implemented to address identified issues and were tracked to closure. The inspector verified the QA program evaluated changes in the ISFSI program to ensure that any changes that were implemented would not decrease the overall effectiveness of the program. The inspectors also determined the Connecticut Yankees 10 CFR 72.212 evaluation report had been appropriately updated.

The inspector verified that Connecticut Yankees aging management activities were performed in accordance with TS requirements and guidance from NUREG-2214, Managing Aging Processes in Storage (MAPS) Report.

c. Conclusion

No violations of more than minor significance were identified.

2. Exit Meeting

On August 2, 2024, the inspector presented the inspection results to Rob Desmarais, ISFSI Manager, Connecticut Yankee Atomic Power Company, who acknowledged the inspection results. No proprietary information was retained by the inspector or documented in this report.
