SUBJECT:

DAILY HIGHLIGHT R. E. GINNA Fiber optic investigation of the secondary side of the "B" steam generator (S/G) has revealed that there is damage to previously plugged tubes in' wedge area #4 where the ruptured tube is located.

Preliminary indications are that one tube is totally severed and several other tubes in the vicinity are severely damaged. RG&E will continue to investigate the peripheral area of the "B" S/G with improved fiber optics and. television cameras as they are j

available. A S/G team from Westinghouse is expected to be on-site tonight.

RG&E is considering a number of options, including cutting a hole in the side of "B" S/G to gain ' ccess to wedge area #4 Rochester Gas and Electric a

Corporation (RG&E) nas informed the NRC that the meeting previously anned for next week on restart requirements has been cancelled.
