BYR 2022-011 ENCLOSURE 1 YANKEE NUCLEAR POWER STATION INDEPENDENT SPENT FUEL STORAGE INSTALLATI ON ANNUAL RADIOACTIVE EFFLUENT RELEASE REPORT JANUARY-DECEMBER2021
YANKEE NUCLEAR POWER STATION INDEPENDENT SPENT FUEL STORAGE INSTALLATION License Nos. DPR-3 and SFGL-13 ANNUAL RADIOACTIVE EFFLUENT RELEASE REPORT January - December 2021 R1d11110n Safety & Control Services April 2022 Prepared by:
Radiation Safety & Control Services 93 Ledge Road Seabrook, NH 03874
EXECUTIVE
SUMMARY
Tables 1 and 2 summarize the quantity of radioactive gaseous and liquid effluents, respectively, for each quarter of 2021. There were no gaseous or liquid releases in 2021. Table 3 summarizes waste shipped off-site for disposal for each half year of 2021. There was no waste shipped for disposal in 2021.
Appendices A and B indicate the status of reportable items per the requirements of the Offsite Dose Calculation Manual (ODCM). There were no reportable items in 2021. Appendix C presents any changes in the ODCM. The ODCM was not revised
. in 2021.
