SUBJECT:

Update to 2022 Radiological Effluent Release Report Vermont Yankee Nuclear Power Station Docket No. 50-271 License No. DPR-28

Dear Sir or Madam:

On May 10, 2023, Vermont Yankee (VY) submitted a copy of the Annual Radiological Effluent Release Report (ARERR) for 2022 in accordance with 10 CFR 50.36a and the VY Off-site Dose Calculation Manual. It has subsequently been identified that there was an error in Table 3 of the ARERR. Accordingly, please find attached a corrected Table 3 to the previously submitted ARERR.

The VY Renewed Facility Operating License Condition 3.E.10 requires that similar information to that contained within the subject report be provided to the Massachusetts Metropolitan District Commission (MDC). However, since the MDC is currently part of the Massachusetts Department of Conservation and Recreation (DCR), this report is being provided to the DCR to satisfy License Condition 3.E.10.

This letter contains no new regulatory commitments.

Should you have any questions concerning this letter, or require additional information, please contact Mr. Thomas B. Silko at (802) 451-5354, Ext 2506.

Sincerely,

~ )(¥ CRD/tbs
