Maine Yankee Atomic Power Company Inspection Report Nos. 07200030/ 2021001 and 05000309/2021001

An announc ed routi ne inspecti on of t he Mai ne Yank ee Atomic Power Company (Mai ne Yankee)

ISFSI was complet ed on October 6, 2021. A n on-site inspecti on was perform ed on September 27, 2021. T he inspecti on incl uded a review of radiati on protection, fir e protection, emergency preparedness, surveillance, maintenance, environmental monitoring, training, quality assurance (QA), and correctiv e acti on programs. T he inspecti on consist ed of observations by the inspector, interviews with Connecticut Yank ee personnel, and a review of records and procedures. T he NRC's program for overseei ng t he saf e operati on of an ISFSI is descri bed in Inspection Manual Chapter (IMC) 269 0, Inspecti on Program for Stor age of Spent Reactor Fuel and Reactor Relate d Greater -Than-Class C W aste at Independent Spent Fuel Storage Installations and for 10 CFR Part 71 Transportati on Packagings."

Based on t he results of this inspection, no findings of significanc e wer e identified.

ii REPORT DET AILS

1. Inspection Scope, Observations, and Conclusion

a. Inspection Scope

The inspector assessed whether Maine Yankee personn el were op erating and maintaining ISFSI programs at an away-from-re actor (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) progr am, Maine Yankee procedures, and 10 CFR Part 72.

AFR ISFSI activities, located at sites where loading oper ations have been completed, are essentially passive operating facilities. The inspectors review was directed toward confirming the ongoing ade quacy of the radiation protection, fire protection, emergency prepa redn ess, surveillance, maintenance, environmental monitoring, training, QA, and corrective action programs.

The inspector observed activities, interviewed site personnel, and reviewe d procedur es and records. The inspector also reviewed changes made to Maine Yankees programs and procedu res 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 Maine Yankees plans and preparations for controlling radiological activities were effective at meeting 10 CFR Part 20 requireme nts. The inspector also verified that special nuclear material (SNM) stored at the ISFSI was prope rly accounted for. Dosimetry records and environmental reports wer e found to be complete, and all employee exposures were below the regul at ory dose limits, and dose to members of the public at the nearest accessible location to the ISFSI were within limits as prescribed by 10 CFR 72.104.

The inspector verified Maine Yankees emergency preparedness progr am was properly coordinated with the appr opriate 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 reviewe d 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 Maine Yankee person nel in accordance with surveillance requir ements in the TS and that Maine Yankees procedures contain back up plans if the primary surveillance method became unavailable. The inspector also verified that transient combustibles were not being stored on the ISFSI pad or in the vicinity of the VCCs and confirmed procedur es were in place to control entry onto the ISFSI pad.

The inspector determined Maine Yankee has a training prog ram which consists of classroom instruction, on-the-job training, and various drills, as well as shift turnover briefings by supervisors and that refresher training was given on a regula r basis. The inspector verified all employees had been trained an d qualified to perform their assigned ISFSI related duties.

The inspector determined that issues were entered into the corrective action prog ram, 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 progra m to ensure that any changes that were implemented would n ot decrease the overall effectiveness of the program. The inspector also determined the Maine Yankees 10 CFR 72.212 evaluation report had b een app rop riately updated.

c. Conclusion

Based on the results of this inspection, no findings of significance were identified.

2. Exit Meeting

On October 6, 2021, the inspector presented the inspection results to Mr. Wayne Norton, President, Maine Yankee Atomic Power Compa ny, who acknowledged the inspection results. No proprietary information was retained by the inspector or documented in this report.
