These results had been previously transmitted by letter dated , November *16, 1979. Attachments 1, 2 and 3 are copies of material presented during the January 10 meeting. is additional information requested at the end'of the meeting. At the conclusion of the meeting, Consumers Power Company agreed t~ meet with the NRC'prior.to our next planned steam generator inspection (late-1981} and ' discuss the iiispectioi;i plan and any unusual or new techniques that may be utilized durini the i~s~ection.
