DPR-77 and DPR-79 NRC Docket Nos. 50-327 and 50-328
Subject:
Supplement to Sequoyah Nuclear Plant, Units 1 and 2 License Amendment Request to Modify Essential Raw Cooling Water Motor Control Center Breakers and to Revise the Updated Final Safety Analysis Report for Sequoyah Nuclear Plant Units 1 and 2 (SQN-TS-17-04)
Reference:
TVA Letter to NRC, CNL-17-150, Sequoyah Nuclear Plant, Units 1 and 2 License Amendment Request to Modify Essential Raw Cooling Water Motor Control Center Breakers and to Revise the Updated Final Safety Analysis Report Sequoyah Nuclear Plant Units 1 and 2 (SQN-TS-17-04), dated March 9, 2018 (ML18071A349)
In the referenced letter, Tennessee Valley Authority (TVA) submitted a request for an amendment to Renewed Facility Operating License Nos. DPR-77 and DPR-79 for the Sequoyah Nuclear Plant (SQN), Units 1 and 2, respectively. The proposed change would modify Essential Raw Cooling Water (ERCW) Motor Control Center (MCC) Breakers and revise the Updated Final Safety Analysis Report for SQN Units 1 and 2 (SQN-TS-17-04).
Based on a verbal request from the Nuclear Regulatory Commission, the enclosure to this letter supplements the reference license amendment request by providing SQN-0-35W716-1 and 2, Single Line Diagrams for the 1A-A, 2A-A, 1B-B, and 2B-B ERCW MCCs.
This supplement does not change the no significant hazards consideration contained in the referenced letter. There are no new regulatory commitments made in this letter. Please address any questions regarding this request to Mr. Edward D. Schrull at (423) 751-3850.
U. S. Nuclear Regulatory Commission CNL-18-054 Page 2 April 11, 2018 I declare under penalty of perjury that the foregoing is true and correct. Executed on this 11th day of April 2018.
