Subject:

Emergency Plan Implementing Procedure Revisions Pursuant to Title 10, Code of Federal Regulations (10 CFR) 50.54(q)(5), and 10 CFR 72.44(f),

the Tennessee Valley Authority {TVA) is submitting a description of changes to the Watts Bar Nuclear Plant (WBN) Radiological Emergency Plan (REP). The affected documents are the WBN Emergency Plan Implementing Procedures (EPIP) listed below:

EPIP Revision Title Effective Date 6 55 Activation and Operation of the Technical 02/25/2021 Support Center (TSC) 13 31 Initial Dose Assessment for Radiological 02/25/2021 Emergencies Description of Changes EPIP-6 revision 55 revised Technical Assessment Manager {TAM)/Technical Assessment Team (TAT) responsibilities to include exit from adverse condition setpoint use. This revision also removed reference to the Emergency Paging System due to it being removing from REP and revised a checklist to include a facility update and a data sheet with a correct turn-on code.

Finally, the revision performed several editorial format changes to align with writers guide and references.

U.S. Nuclear Regulatory Commission WBL-21-011 Page 2 March 9, 2021 EPIP-13 revision 31 revised a conversion factor for the Unit 1 Condenser Vacuum Exhaust Radiation Monitor (1-RM-90-119) due to detector replacement, updated and deleted footnotes with respect to 1-RM-90-119, and added a step to stop use of this site procedure when the Central Emergency Control Center (CECC) is staffed and has assumed responsibilities for Dose Assessment actions .

The above changes were evaluated in accordance with 10 CFR 50 .54(q)(3) and 10 CFR 72.44(f). TVA determined that the changes did not reduce the effectiveness of the WBN REP .

The WBN REP, as revised , continues to meet the requirements in Appendix E to 10 CFR 50 and the planning standards of 10 CFR 50.47(b).

There are no new regulatory commitments in this letter. Please direct all questions concerning this matter to Mike White, Emergency Preparedness Manager, at (423) 365-3232 .
