SAFETY EVALUATION BY THE OFFICE OF NUCLEAR REACTOR REGULATION RELATING TO PERFORMANCE ENHANCEMENT PROGRAM, FINDING 4-10 PUBLIC SERVICE COMPANY OF COLORADO FORT ST. VRAIN NUCLEAR GENERATING STATION DOCKET NO. 50-267

1.0 INTRODUCTION

By letter dated February 11, 1987, Public Service Company of Colorado (PSC) has submitted additional information in respect to Finding 4-10.

Finding 4-10 states that the licensee should verify to the staff that the functional acceptability of equipment being returned to service will be checked or verified by the shift supervisor, regardless of the reason for having removed the equipment from service (e.g., surveillance testing, inspection, maintenance, modification,etc.).

The information contained in the PSC letter dated February 11, 1987 supplements information provided by PSC in a letter dated July 23, 1976.

The staff had previously provided a partial evaluation in a letter dated December 12, 1986. The following is our evaluation of the information providad by PSC in their letter dated February 11,1987.

Equipment may be removed from service for one of four reasons: surveil-lance testing, plant maintenance, modification installation or special testing. Different plant procedures govern the return to service of equipment that is removed for service for the above noted four reasons.

1. Surveillance Testing Equipment that is removed from service for surveillance testing 'is returned to service using established procedures. These procedures .

provide for the checking for functional acceptability prior to l returning the equipment to service. All surveillance tests have requirements for noi.ifying the shift supervisor of test performance.

Shift supervisor approval must be obtained prior to beginning a test, and he must be notified of test completion and results. l

2. Plant Maintenance Plant maintenance procedures are developed under administrative pro-cedures that provide for developing and documenting post-maintenance test activities. Post-Maintenance Testing Instruction Sheets (PMTs) are used when maintenance is performed on specific equipment items at 8704290352 870422 PDR ADOCK 05000267 P PDR **

the component level. A completed PMT must be attached to every com-pleted Station Service Request (SSR) unless the SSR clearly identi-fies that no PMT was required. PMTs are performed in most cases by workmen from the I&C group with the approval and assistance of the Operations Department. The shift supervisors concur with the com-pleted PMT.

3. Modification Administrative procedures require that Function Tests (FTs) and Cold Checkout Tests (CCTs) he prepared for design change activities where appropriate. Plant management and the Plant Operations Review Com-mittee are involved in the review and approval FTs and CCTs. The shift supervisor must be informeo of test completion, test results, and sign-off on the FT, CCT, and completed work package.

4. Special Tests Special Tests are performed by either the Operations Group or the I&C group with the coordination and approval of operations. The shift supervisor's approval must be obtained prior to performing these tests, and the shift supervisor must be informed of test results and acknowledge test completion by signing the test form.

2.0 CONCLUSION

PSC has described certain activities that are performed by the shift supervisor in respect to the surveillance testing program and maintenance activities that show that the shift supervisor has control of the functional acceptability of returned equipment. The staff finds that Fort St. Vrain has been responsive to NRC assessment reports and to the consultant's independent recommendations.
