Dear Mr. O'Reilly:

SUBJECT: Grand Gulf Nuclear Station Unit 1 Docket No. 50-416 License No. NPF-13 File 0260/L-835.0 ADS Valve Air Booster Compressors Not Operating Reference: LER 82-072/01 T-0 AECM-82/465 During Non-Nuclear Heatup, it was discovered that the ADS Valve Air Booster Compressors were not operating. This resulted in air pressure in the ADS Valve Air receivers having low pressure.

Since the plant was in operational mode 3, loss of ADS caused entrance into the LCO per l

T.S.3.5.1.b.2.

Attached is LER-82-072/01 T-0 with supplementary information.

Yours truly JPM: sap Attachment cc:
