VIRGINIA ELECTRIC AND POWER COMPANY . SURRY POWER STATION UNITS 1 & 2 CLARIFICATION OF COMMITMENT Serial No. NOiRJS Docket Nos. License Nos. 90-329A 50-280 50-281 DPR-32 DPR-37 NRC INSPECTION REPORT NOS. 50-280/90-07 AND * 50-281 /90-07 It has been called to our attention that a discrepancy exists between a written _response provided to your inspection team and the documentation of that response in Inspection Report Nos. 50-280/90-07 and 50-281/90-07 dated May 22, 1990. The discrepancy concerns temporary

• action taken to correct a weakness identified by your * inspection team in our electrical equipment post-maintenance testing program. Our response, dated March 30, 1990, read "The process will be formalized by a revision to SUADM-M-27 which will require system engineering review of, electrical maintenance testing for concurrence and to specify any additions if required." System engineering review of the assigned testing was deemed necessary due to the limited guidance provided by SUADM-M-27 for specifying electrical post-maintenance testing for safety-related component Inspection Report 90-07, however, further identifies that "qualified electrical system engineers" will specify post-maintenance testing in these areas. In accordance with our March 30, 1990 response, a procedure change to SUADM-M-27 was approved and implemented to satisfy this commitmen The procedure change did not require ".qualified electrical system engineers" specify post-maintenance testing* as stated in the referenced inspection report. The procedure change only required that system engineering review the specified testing and make additions as required . 9011060215 901026 PDR ADOCK 05000280 G! PDC i ', I. * We have subsequently determined that a more efficient and consistent temporary method for specifying post-maintenance test requirements could be implemente A matrix has been developed which provides guidance for specifying safety-related electrical post-maintenance testing. The matrix has beer:i incorporated into SUADM-. M-27 for use by the Planning Department and the Electrical Maintenance Group. Implementation of the test matrix to determine post-maintenance test requirements supersedes our March 30, 1990 commitment for system engineering review.
