Docket No. 50-482 and 72-79: Correction to 2023 Annual Radioactive Effluent Release Report - Report 47 Commissioners and Staff:

The reference submitted the Wolf Creek Generating Station Annual Radioactive Effluent Release Report - 47, for the period of January 1 to December 31 of 2023. Subsequent to the submittal of this report, the table in Section VI.C (page 6) Dose to a Member of the Public from Activities Inside the Site Boundary was updated. The total dose value for the last row ISFSI Dry Cask South (at nuisance fence on south side) was reduced from the initially reported value of 1.01E+02 mrem (101 mrem) to the new value of 2.51E+01 mrem (25.1 mrem).

The reduction in dose leading to a revision of the report was identified and documented in the Wolf Creek Generating Station corrective action program under condition report 10033834.

The enclosure to this letter includes two updated pages. The first is an updated title page reflecting Revision 1 of the 2023 Report No. 47. The second is an updated page 6 which contains the corrected dose value within the table as described above.

This letter contains no commitments. If you have any questions concerning this matter, please contact me at (620) 364-4204.

Sincerely, Dustin T. Hamman DTH/jkt

The William Allen White Building occupancy was based on normal working hours of 2,000 per year. The Submersion, Inhalation and Ground Plane pathway doses were added to derive the total dose. All calculations were performed in accordance with the methodology and parameters in the ODCM.

• The Radiation Protection (RP) department monitors various locations and buildings in the vicinity of the ISFSI area to verify exposure is within regulatory limits in addition to the monitoring done by REMP. The calculated doses here are based on a conservative 2,000 working hours per year and do not subtract off background readings.

• • This fence is designed to delay any potential entry into the Dry Cask Area. It is identified as the nuisance fence on the south side of the storage area.
