CONNECTICUT YANKEE ATOMIC POWER COMPANY - NRC INDEPENDENT SPENT FUEL STORAGE INSTALLATION INSPECTION REPORT NOS.

07200039/2021001 AND 05000213/2021001

Dear Mr. Lenois:

On September 30, 2021, the U.S. Nuclear Regulatory Commission (NRC) conducted a safety inspection at the Connecticut Yankee Atomic Power Company (Connecticut Yankee)

Independent Spent Fuel Storage Installation (ISFSI). The inspection examined activities under your licenses as they relate to safety and compliance with the Commissions regulations and conditions of your licenses. The inspection consisted of observations by the inspector, interviews with site personnel, and a review of procedures and records. The results of the inspection were discussed with Mr. Wayne Norton, you, and members of your staff during a phone call on October 6, 2021. The enclosed report presents the results of this inspection.

Within the scope of this inspection, no violations were identified.

In accordance with 10 CFR 2.390 of the NRCs "Rules of Practice," a copy of this letter, its enclosure, and your response, if you choose to provide one, will be made available electronically for public inspection in the NRC Public Document Room or from the NRC document system (ADAMS), accessible from the NRC Web site at http://www.nrc.gov/reading-rm/adams.html. To the extent possible, your response should not include any personal privacy, proprietary, or safeguards information so that it can be made available to the Public without redaction.

EXECUTIVE SUMMARY

Connecticut Yankee Atomic Power Company

Inspection Report Nos. 07200039/2021001 and 050000213/2021001

An announced routine ISFSI inspection of the Connecticut Yankee Atomic Power Company ISFSI was completed on October 6, 2021. An on-site inspection was performed on September 30, 2021. The inspection included a review of radiation protection, fire protection, emergency preparedness, surveillance, maintenance, environmental monitoring, training, QA, and corrective action programs. The inspection consisted of observations by the inspector, interviews with Connecticut Yankee personnel, and a review of records and procedures. The NRC's 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 Packaging."

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

Inspection Report No. 07200039/2021 and 05000213/2021001

REPORT DETAILS

1. Inspection Scope, Observations, and Conclusion

a. Inspection Scope

(Inspection Procedure 60858)

The inspector assessed whether Connecticut Yankee personnel were operating 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 confirming the ongoing adequacy of the radiation protection, fire protection, emergency preparedness, surveillance, maintenance, environmental monitoring, training, QA, and corrective action programs.

The inspector observed 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

The inspector determined that Connecticut Yankees plans and preparations for controlling radiological activities were effective at meeting 10 CFR Part 20 requirements.

The inspector also verified that special nuclear material (SNM) stored at the ISFSI was properly accounted for. Dosimetry records and environmental reports were found to be complete, and all employee exposures were below the regulatory 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 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 daily temperature monitoring of the vertical concrete casks (VCCs)was performed by Connecticut Yankee personnel in accordance with surveillance requirements in the TS and that Connecticut Yankees procedures contain back up plans if the primary surveillance method became unavailable. The inspector determined the licensee continued to focus on pad conditions and pad repairs and upgrades were expected to be completed in 2023. The inspector also verified that transient combustibles were not being 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.

Inspection Report No. 07200039/2021 and 05000213/2021001

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

The inspector determined that issues were entered into the corrective action program, prioritized, and evaluated commensurate with their safety significance, 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 inspector also determined the Connecticut Yankee 10 CFR 72.212 evaluation report had been appropriately updated.

c.

Conclusion

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

2. Exit Meeting

On October 6, 2021, an exit meeting was conducted virtually with the licensee. The results of the inspection were discussed with Mr. Wayne Norton, President and Jim Lenois, ISFSI Manager. No proprietary information was retained by the inspector or documented in this report.
