Dear Mr. Cerry:
In our letter of flay 1980 ue recormnded that you initiate a program to inspect the keyway and bore areas of your low pressure turbine discs for stress corrosion cracking.
This action was prompted by the discovery of such cracks in Westinghouse turbines.
So far, the inspe': tion program has covered one or more low pressure rotors at 15 nuclear plants using GE turbines. No clear indication of stress corrosion cracking has been discovered, although indications of water cutting and/or crosien have been observed in several turbines.
In view of these findings, we have decided to discnntinue the NRR staff monitoring of these inspections. Howver, nomal activities of the Office of Inspection and Enforceaent will continue.
We reconnend that you continue to perfom disc inspections, as appropriate, and continue to work with General Electric Conpany to establish safe inspection schedules. Should ycu find any significant degradation, such as stress corrosion cracking, we vould expect you to prrptly report it in the normal ranner.
Sincerely, ORIGUIAL SIGNED BY Philip J. Polk, Project !% nager Operating Peactors Branch f2 Division of Licensing cc:
