Dear Hr. Finfrock:

SUBJECT:
TURBINE DISC CRACKIn.J (0YSTER CREEK)
' Ve 7
(Task Action No. B-46) m m
In our letter of May 1980 we recomended that you initiate a program to inspect the keyway and bore areas of your low pressure discs for stress corrosion cracking. This action was prompted by the discovery of such cracks in Westinghouse turbines.
So far, tne inspection 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 erosion have been observed in several turbines.
In view of these findings, we have decided to discontinue the HRR staff monitedng of these inspections. Normal activities of the Office of Inspection and Enforcement will continue of course.
We recomend tnat you continue to perform disc inspections, as appropriate, and continue to work with General Electric Company to establish safe inspection schedules. Should you find any significant degradation, such as stress corrosion cracking, we would expect you to promptly report it in the normal manner.
Sincerely.
