TVA Letter to NRC dated, July, 12, 2006, Sequoyah Nuclear Plant (SQN) - Units 1 and 2 - Technical Specifications (TS) Change 06-03 Ultimate Heat Sink (UHS) Temperature Increase and Elevation Changes Reference 1 requested additional information regarding the TVA proposed license amendment for revising the SQN ultimate heat sink limiting condition of operation (LCO) under Reference 2. Several discussions have been held between NRC and TVA regarding the depth of these questions. On July 18, 2007, NRC staff provided TVA personnel additional clarification of select questions. In light of these
U.S. Nuclear Regulatory Commission Page 2 July 20, 2007 clarifications, additional time will be needed to address the postulated dual unit shutdown impact associated with UHS licensing basis and limiting fouling factors for emergency diesel generators. This has been coordinated with SQNs NRC Project Manager, Brendan Moroney, and agreement was reached to provide our response by August 20, 2007.
