Dear Mr. Rusche:

i My letter of April 13, 1976 identified that as a result of inspections performed at another Babcock and Wilcox reactor, which revealed evidence of wear to the reactor vessel surveillance specimen holder tube journal bearings that it was anticipated that Oconee 1 would be shutdown in the near future to remove the holder tubes and associated spring loaded retaining devices for the duration of Cycle 3 operation. j My letter of April 15, 1976 in reference to Oconee 3 transmitted proposed changes to the Oconee Nuclear Station Technical Specifications. These proposed i

specifications to assure that provided limiting conditions for operation for Oconee 3. Cycle 1 j the possibility of further degradation of the reactor vessel '

surveillance specimen holder tubes is minimized and to assure that, in the unlikely event of such an occurrence, a failed holder tube could be detected  ;

and corrective action taken. Similar changes to the Oconee Technical ['

Specifications have not been proposed for Oconee 1 operation until the previously identified shutdown is accomplished as that shutdown is imminent.  ;

l llowever, restrictions consistent with those proposed for Oconee 3, Cycle 1 have been imposed on Oconee 1, Cycle 3 operation until the unit is shutdown for holder tube removal. '

Very truly yours, i u. .- (O . & ^-

I William O. Parker, Jr.
