Dear Mr. Grier:
This letter serves to confirm information provided by telephone to NRC Inspector Mr. R. Gallo by Mr. A. R.
Sabol of PP&L on April 28, 1980.
During that conversation, Mr. Gallo was advised that the subject condition was under evaluation for x'eportability under the provisions of 10CFR50.55(e),
The deficiency involves premature time out and drifting set points for penumatic time delay relays.
PP&L and Bechtel are studying the deficiencies associated with both Agastat 7000 series and General Electric CR 2820 relays.
These relays ax'e used in safety related systems and hence their improper operation could affect the safe operation of the nuclear power plant.
Therefore, the deficiency has been determined to be rep'ortable under the provisions of 10CFR50.55(e).
Bechtel and PP&L are in the process of analyzing the safety impact of the deficiency and are formulating a corrective action plan.
Bechtel has issued MCAR 1-54 to document the deficiency and effect correction.
Since the details of this report provide information relevant to the reporting requirements of 10CFR21, this correspondence is considered to also discharge any foxmal responsibility PP&L may have for reporting in compliance thereto.
We will advise the Commission of a date by which a final report will be made available.
