Dear Sir:
Subject:
Maira Yankee Paportable Occurrence #80-014/0lT-0 Pursuant to the requirements of Technical Specificaticns 5.9.1.6.i, the Maine Yankee Atcmic Pcwer Ccnpany he.reby subtits the following report.
Pralimiery results frcm the vessel wall irradiated surveillance capsule indicates a considerably higbar Rrg shift than originally i
I predicted. These results are fran the Charpy V-notch inpact data only as the dosimetry data will not be ccupleted for appraxmately 30 days.
As a conservative measure Maine Yankee is presently revising the appropriate heat up and cooldown curves to reflect the prelirinary findings and will operate using the revised curves until all data is available. Final revisicn of these cuIves will be made after the analysis is ccuplete.
Based on the telephone conversation between Mr. T. Martin and Mr. D. E. Moody on June 4,1980, it is thtood that the 14 day follcw-up report has been waived to allcw time for the dosimetry data to be received The folicw-up report will be foraarded wtan all data is receivet ad an evaluatica made. This is expected to be ccuplete in approvin. sly 30 days.
