SUBJECT: NRC INSPECTION REPORT NO. 50-348/92-30 AND 50-364/92-30

,

This refers to the inspection conducted by M. D. Hunt of this office on

November 16-20, 1992. The inspection included a review of activities autho-

rized for your Farley facility. At the conclusion of the inspection, the

findings were discussed with those members of your staff identified in the

report. .

Areas examined during the inspection are identified in the report. Within

these areas, the inspection consisted of selective examinations of procedures

and representative records, interviews with personnel,-and observation of

activities in progress.

.

Within the scope of the inspection, violations or deviations were not identi-

fled. However_, our review of your GL 89-10 Motor Operated Valve (MnV) program

indicated that programatic issues associated with differential. pressure

testing to the maximum extent possible and the acceptability of using the

MOVATS data base for valve setup remains open. Additional information

regarding NRC inspection fitdings 50-348, 364/91-201-02-and 91-201-03 is

necessary for the NRC to complete the evaluation of the acceptability of your-

GL 89-10 M0V program. You are requested to provide the following information:

Your ' plans for differential pressure -(d/p) testing to the maximum extent

practicable since the limited d/p testing that was performed during your

, 1992 indicated that M0 VATS data base and vendor calculations underpr-

edicted the required minimum thrust approximately: 25% of the time. This-

should also include your controls for selection and screening of valves

that will or will not be d/p -tested.

Information' that demonstrates that your M0V program will clearly document-

assumptions and margins used in the thrust calcul nions to compensate for

uncertainties in the MOVATS data base and vendor calculations.
