SUMMARY
OF AUGUST 26, 2004, MEETING WITH TENNESSEE VALLEY AUTHORITY AND WESTINGHOUSE, ON STEAM GENERATOR REPLACEMENT AT WATTS BAR NUCLEAR PLANT, UNIT 1 (TAC NO. MC3937)
On August 26, 2004, a Category 1 public meeting was held between the U.S. Nuclear Regulatory Commission (NRC) and representatives of Tennessee Valley Authority (TVA, licensee), Westinghouse, and Bechtel at NRC Headquarters, Two White Flint North, 11555 Rockville Pike, Rockville, Maryland. The purpose of the meeting was to discuss the licensees upcoming plans to replace existing steam generators (SGs) at Watts Bar Nuclear Plant (WBN),
Unit 1, with new SGs.
A list of attendees is provided in Attachment 1 and the licensees handouts provided at the meeting are included in Attachment 2.
Mr. Paul Trudel, the licensees representative, gave a brief presentation indicating that Sequoyah Nuclear Plant (SQN) Unit 1 recently replaced SGs and these lessons learned will be incorporated at WBN Unit 1. The licensee also explained similarities and differences from the SQN Unit 1 SG replacement process. Mr. Trudel presented salient features of the replacement SGs and compared it to the existing units. He discussed major activities and the status of the current projects associated with SG replacements.
The licensee discussed changes to the specific design and operational areas requiring NRC approval. The most notable changes include the bar lock mechanical couplers, opening of penetrations in the shield building dome, and nuclear steam supply system coolant reanalysis.
The licensee provided a list of computer codes that they intend to use for reactor coolant loop reanalysis which were the same computer codes that were approved by the NRC staff for the AP600 piping system analysis. The licensee provided a potential schedule of license amendment submittals and proposed 10 CFR 50.59 changes and the evaluations to support the replacement of the SGs.
