In Reference 1, Tennessee Valley Authority (TVA) submitted a request for an amendment to the Technical Specifications (TS) for Watts Bar Nuclear Plant (WBN) Unit 2. The proposed amendment revises the WBN Unit 2 TS 3.7.8, Essential Raw Cooling Water (ERCW), on a one-time basis to support performance of maintenance on 6.9 kiloVolt (kV) Shutdown Board (SDBD) 1A-A and associated 480 Volt (V) boards and motor control centers (MCC). In Reference 2, TVA submitted a supplement to the proposed amendment request to reflect a change to Note 1 to the proposed new WBN Unit 2 TS 3.7.8, Condition A.
U.S. Nuclear Regulatory Commission CNL-19-113 Page 2 November?, 2019 In the revised Section 3.2.4 of the enclosure to Reference 2, TVA stated:
"While Figure 1 does show ERCW temperatures exceeding 71°F towards the middle to later periods of May, it should be noted that the planned maintenance of the 6,9 kV SDBD 1A-A and associated 480 V boards and MCCs is planned to be completed within the first two weeks of the U1R16 outage following WBN Unit 1 being defueled (i.e., the planned maintenance is planned to be completed by May 7, 2019)."
The quoted paragraph should have staled May 7, 2020, instead of May 7, 2019.
There are no new regulatory commitments associated with this submittal. Please address any questions regarding this request to Kimberly D. Hulvey at (423) 751-3275.
I declare under penalty of perjury that the foregoing is true and correct. Executed on this 7th day of November 2019.
