Seabrook Station Supplement to 2021 Annual Radioactive Effluent Release Report

Reference:

NextEra Energy Seabrook, LLC letter SBK-L-22044, 2021 Annual Radioactive Effluent Release Report, dated April 29, 2022, (ML22119A266).

Pursuant to 10CFR 50.36a (a).2 and Technical Specification 6.8.1.4, NextEra Energy Seabrook,

LLC, in the above reference, submitted the Annual Radioactive Effluent Release Report for 2021 on April 29, 2022. It was determined that the following Tables were inadvertently omitted from of that submittal :

Table IA, Gaseous Effluents - Summation of all Releases Table lB, Gaseous Effluents - Elevated Releases - Batch Table IB, Gaseous Effluents -Elevated Releases - Continuous Table IC, Gaseous Effluents - Ground Level Releases - Batch Table 1 C, Gaseous Effluents - Ground Level Releases - Continuous Table 2A, Liquid Effluents - Summation of all Releases Table 2B, Liquid Effluents - Batch Mode Table 2B, Liquid Effluents - Continuous Mode

Please insert the Attachment to this letter that contains the Tables listed above in Enclosure 1 of NextEra Energy Seabrook, LLC letter SBK-L-22044, 2021 Annual Radioactive Effluent Release Report for completeness.

Should you have any questions regarding this letter, please contact David Robinson, Chemistry Department Manager, at (603) 773-7496.
