Heatup/Cooldown Curves and Associated LTOP Setpoint Modification R.E.Ginna Nuclear Power Plant Docket No.50-244
Dear Mr.Johnson:
During the NRC review of RGGE's February 15, 1991 proposed license amendment to modify heatup/cooldown curves and the associated LTOP setpoint to meet Regulatory Guide 1.99, Revision 2 methodology, a question was raised concerning reactor vessel weld material identification.
In Table 5.3-5 of the Ginna Station UFSAR, weld control number SA-847 is identified.
as having a nickel content: of 0.39 weight percent, and.a copper content of 0.20 weight percent-.These values are nominal weld material values.For licensing-purposes, the chemical composition used is.a.more conservative 0.54 weight percent nickel, and 0.25 weight percent copper.These latter values will be reflected in the next UFSAR update, December.1991.It should be noted that the weld control number SA-847 is identified as Seam WR-19 in some RG&E and Westinghouse documents.
These two designations identify the same weld.Very truly yours, I<Nial I HOQ'OO QO~-4$, 0AO ctO IN'A wet N lO'K wQ (hQ Q Robert C.Mecredy GJW/165 xc: Mr.Allen R.Johnson (Mail Stop 14D1)Project Directorate I-3 Washington, D.C.20555 U.S.Nuclear Regulatory Commission Region I King of Prussia, PA 19406/arrl frrn+7~z, pinna Senior Resident Inspector@f959//p 1%I Y)~0
