SUBJECT:

Grand Gulf Nuclear Station Units 1 and 2 Docket Nos. 50-416/417 PRD - 80/23, Status Rep 8 Calibration Services From Computer Sciences Corporation AECM-80/115 On April 29, 1980, Mississippi Power & Light Company notified Mr. M. Hunt of your office of a Potentially Reportable Deficiency (PRD) at the Grand Gulf Nuclear Station (GGNS) construction site. The deficiency concerns nonconfor-mances associated with calibration services provided to MP&L by Computer Sciences Corporation (CSC). These noncomformances were noted during an April, 1980, MP&L audit of the CSC calibration facility, NSTL Station, Mississippi.

To date our investigation has revealed no significent deficiencies con-by CSC. an adverse safety impact associated with MP&L equipment calibrated stituting This is based primarily on an evaluation of a representative sample of MP&L equipment calibrated by CSC.

Our evaluation as to the extent of this problem is incomplete. We are currently evaluating proposed actions for further sampling and investigation.

,; We expect 22, 1980. to provide Our status reportour final report on this matter no later than July is attached.

AITACHMENT TO AECM-80/115 STATUS REPORT ON PRD-80/23 I. DESCRIPTION OF DEFICIENCY This deficiency concerns nonconformances associated with calibration

. services provided to MP&L by Computer Sciences Corporation (CSC). These nonconformances were noted during an April, 1980, MP&L audit of the CSC calibration facility, NSTL Station, Mississippi.

In one case it was noted that MP&L equipment was calibrated with a standard having a downgraded accu acy. A second nonconformance involved the use of a standard for calibration that was identified as out of tolerance. MP&L was not notified of either of these conditions. CSC has a contractual commitment to MP&L to provide notification of the calibra-tion of MP&L Measuring and Test Equipment (M&TE) with standards observed 1

to be out of allowed tolerance. CSC has in addition committed to identify any M&TE calibrated with suspect standards. CSC failed to provide this notification and apparently had no method or procedures for providing such notification.

II. SAFETY IMPLICATIONS To date our investigation has revealed no significant deficiencies constituting an adverse safety impact associated with MP&L equipment calibrated by CSC.

III. CORRECTIVE ACTIONS MP&L selected a sample listing of MP&L Measuring and Test Equipment (M&TE) items calibrated by CSC. This sampling included M&TE employed to calibrate safety related equipment at GGNS. The calibration information for this M&TE and the associated standards was evaluated by CSC for out of tolerance conditions. As a result of this sampling, no significant deficiencies were revealed. We are currently evaluating proposed actions for further sampling and investigation.

CSC is currently developing the required procedures and administra-tive controls that will provide for the notification to MP&L of the use of an out of tolerance standard.

This deficiency is tracked under MP&L Corrective Action Request (CAR)

Nos. 257 and 258 and PRD-80/23.
