Mr. J. P. O'Reilly, Director

Dear Mr. O!Reilly:

SUBJECI: Grand Gulf Nuclear Station Units 1 and 2 Docket Nos. 50-416/417

?ile 0260/15525/15526/15521 RII:WPA 50-416/80-19 AECM-80/250 Mississippi Power & Light Ccmpany received a notice of viola-tion as Enclosure 1 to your letter dated September 11, 1980 which transmitted IE Inspection Report 80-19.

This violation concerns calibration and. control procedures for torque wrench multipliers.

Although our response to the notice of violation was due October 6,1980, Mississippi Power & Light is submitting the re-sponse on this date due to the complex nature of the violation, our desire to consider the applicability of 10CFR50.55(e) and to include that determination as part of this report. Therefore, the following is submitted in response to the notice of violation.

CORRECTIVE STEPS TAKEN AND RESULTS ACHIEVED The Constructor conducted a review to determine where torque multi-pliers were used for Quality Control acceptance. This review re-vealed that multipliers had been used on the Hori:: ental Transfer Tube Seismic Brace; Residual Heat Removal Pumps A, B, & C; the High Pressure Core Spray Pump; and the Low Pressure Core Spray Pump.

The bolting on the pumps has been retorqued using certified mul-tipliers. Recorquing of the Transfer Tube has not been completed but is documented on Condition Reoort 4151.

Mississippi Power & Light identified this' item as a potentially reportable deficiency and notified the NRC on October 7, 1980.

This is being tracked by PRD Number 30/62.
