March 1, 1979 Docket No. 50-265 Mr. Cordell Reed Assistant Vice President Commonwealth Edison Company P. O. Box 767 Chicago, Illinois 60690 Gentlemen:
Re: Quad Cities Unit No. 2 Currently you are administrative 1y applying revised reactor coolant pressure-temperature limits at your facility which reflect the possible use of an atypical weld wire in the reactor vessel welds.
Babcock & Wilcox has continued their investigation of this possible problem and all evidence developed to date strengthens our belief that the likelihood that atypical weld wire was actually used in reactor vessels is very low. Further information, including effects of radiation on the atypical material is scheduled to be submitted within the next several months.
Nevertheless, we believe that pending final resolution of this matter, expected by June 1979, continued administrative application of the revised limits is appropriate.
Sincerely, m*
I
