Dear Mr. Del George:
RE:
DRESDEN 3 AND QUAD CITIES 1 & 2
. SEP 1 6 1981 In our letter of May 1980 we recorrmended that you initiate a program tb-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 1n Westinghouse turbines.
So far, the inspection program has covered one or more low pressure rotors at 15 nuclear plants using GE turbines.
No clear indicatfon*of stress corrosion cracking has been discovered, although indications of water cutting and/or erosion have been observed in sev~ral ~urbtne~*f -
. *:. -~J. *~(~*...
In view of these findings, we have decided to discontinue the NRR staff monitoring of these inspections. Nonnal activities of the Office of Inspection and Enforcement will continue of course.
We reconmend that you continue to perfonn disc inspections*, as appro-priate, and continue to work with General Electric Company ¢0 esta~lish safe inspection schedules. Should you find any significant~"egradation, such as stress corrosion cracking, we would expect you to promptly' report 1 ~ 1 n the nonna 1 manner.
