Contrary to the above, on the dates indicated below, the following surveil-lan'ce test procedures were performed and steps implementing verification and independent verification of system response and system restoration were not completed: PNPS Procedures 8.M.2-1.S.8.4, Logic System Functional Test of System

"B" Standby Gas Treatment Initiation, Reactor Building Isolation and Outboard Drywell Isolation Valves on June 26, 198 . PNPS Procedure 8.M.2-1.4.1, Revision 12, Main Steam High Temperature Sensors Functional Test, on April 5, 1986, and May 7, 198 This is a Severity Level V Violation (Supplement I).

established in 1985. The inspector will review the individual discrepan-cies, and any compensatory measures taken, to determine compliance with the technical specifications during a future inspection (86-25-10).

Boston Edison Quality Assurance Manual (BEGAM) Section 16 establishes the corrective action program, and requires that deficiencies be identified and processed in accordance with Section 15 of the BEQAM. Section 15 states that nonconforming components are documented and reported via a Failure and Malfunction Report (F&MR). PNPS procedure 1.3.24, Revision 12, Failure and Malfunction Reports states that an F&MR shall be initiated

.whenever any abnormal plant condition has the potential to adversely affect safe operation Timely and effective processing of an F&MR is important in establishing-operations staff awareness of potential or actual ~ problems. Technical specifications _ require establishment of a fire watch within _one hour of finding an inoperable fire barrie Failure to effectively use the cor-rective action program both as the individual discrepancies were identified, and after the summary of discrepancies was compiled on July 2,1986, demon-strates a programmatic weakness. ~ The inspector informed the licensee that the above constitutes a violation of 10 CFR 50 Appendix B (86-25-09).

8.0 Local Leak Rate Testing Status During this reporting period, 1 type "B" as-found local leak rate test (LLRT) failure was found. The outboard flange of the inboard drywell purge exhaust valve had leakage greater than 20 sim. This leakage will be. quantified prior to its repair work. Also 3 type "C" as found LLRT failures were found, i.e. , the outboard drywell purge exhaust valve, the inboard post accident sample system (PASS) return valve, and the inboard drywell' equipment drain valve. Between August 4, 1986 and April 11, 1986, 87 of approximately 101 type "B" components have been tested with 2 fail-ures, and 123 of approximately 133 type "C" components have been tested with 15 failure During conduct of leak rate testing on the containment floor drain sump isolation valves the inspector noted that while two LLRTs had been per-formed on that day, no test cart bypass valve leak test had been performed as required by procedure. This concern had been previously identified by the. inspector and discussed with licensee personnel. While the signifi-cance of the incidents is minor, the licensees failure to correct them raises concern. ~The inspector discussed this problem at the exit meetin l l
