KEWAUNEE POWER STATION UNIT 1 MILLSTONE POWER STATION UNITS 2 AND 3 NORTH ANNA POWER STATION UNITS 1 AND 2 SURRY POWER STATION UNITS 1 AND 2 ALTERNATIVE REQUESTS FOR USE OF ASME CODE CASES N-756 AND N-757 WITHDRAWAL OF CODE CASE N-756 By letter dated July 25, 2007 and supplemented on November 9, 2007 (Serial Nos. 07-0416 and 07-0416A), DEK, DNC, and Dominion requested approval to use the alternative rules of ASME Code Cases N-756 and N-757.
These Code Cases contain alternative rules for the design of non-welded Class 1, 2, and 3 valves, 1-inch nominal pipe size (NPS) and smaller.
Based on telephone calls with the NRC staff on December 18, 2007 and again on January 10, 2008, which included concerns related to the transient analysis needed to address a Class 1 valve, Dominion is hereby withdrawing the request to use Code Case N-756 as an alternative from the pending proposal.
If you have questions or require additional information, please contact Mr. Thomas Shaub at (804) 273-2763.
