AUMHORIZATION OF A8M BOIL•R AhW L) PSSUME VESSEL (36PV) CODE CAS2 N-460
Enclosed is a copy of AM36 Code Case 11-460, which was approved by AM on July 27, IM88. TVA has reviewed the application of this case and plans to apply it for the determination of the examination coverage for Class I and 2 welds at its nuclear plant sites. The use of this case would define what "essentially 100%" means in the notes of Tables 11-2500-1 and IDIC)2500-1 of Section 11, Division 1, of the Code and thus would reduce the number of welds/coaponents necessitating request for relief. NUC concurrence for use of this Code Case by TVA is requested by Jamnary 12, 1990. If you have any further questions, please telephone F. L. Ginn at 615-751-7667.
Very truly yours,
TanUEESEH VALLEY AUTHOITYn
Manager, Nuclear Licensing and Regulatory Affairs
