| 2 Monthly Surveillance Observation (61726)
| |
| The inspectors observed surveillance activities of safety related systems and components to ascertain that these activities were conducted in accordance with license requirements. The inspectors observed portions of 13 selected surveillance tests including all aspects of the Steam Generator "A" Steam Pressure (PT 474) Operability Test, (STP 303.005).
| |
| | |
| The inspectors also verified that required administrative approvals were obtained prior to initiating the test, testing was accomplished by qualified personnel, required test instrumentation was properly calibrated, data met TS requirements, test discrepancies were rectified, and the systems were properly returned to servic During this inspection period, personnel in general, who performed the surveillance procedures were knowledgeable and appeared to have familiarized themselves with the procedures prior to the performance of a particular surveillance procedur Coordination and communications between the several disciplines required to perform STP's were adequat Parts, components, test equipment or materials used by test personnel during scheduled surveillance testing activities were found to be properly documented on the associated implementing work requests and the STP' No violations or deviations were identifie . Monthly Maintenance Observation (62703)
| |
| The inspectors observed mair.tenance activities of safety related systems and components to ascertain that these activities were conducted in accordance with approved procedures, TS and appropriate industry codes and standards. The inspectors also determined that the procedures used were adequate to control the activity, and that these activities were accomplished by qualified personne The inspectors independently verified that equipment was properly tested before being returned to service. Additionally, the inspectors reviewed several outstanding job orders to determine that the licensee was giving priority to safety related maintenance and a backlog which might affect its performance was not developing on a given system. The following specific maintenance activities were observed in whole or in part:

| equipment, the control of maintenance and surveillance activities in progress, the implementation of radiatinn protective controls and the physical security plan. Tours were conducted during normal and random off hour period In general, the operating crews were observed to be making good use of their time, when not occupied with the normal operating routine. They were observed making needed procedure changes, reviewing procedures, and conducting on-the-job training for those standing watch under instructio Operations watch standing activities and the composition of control room logs was being accomplished in Accordance with the requirements of the controlling procedures and directive No violations or deviations were identifie . ESF System Walkdown (71710)
| |
| The inspectors verified the operability of an engineered safety features (ESF) system by performing a walkdown of the accessible portions of the Component Cooling Water Syste The inspectnrs confirmed that the licensee's system lineup procedures matched plant drawings and the as-built configuratio The inspectors looked for equipment conditions and items that might degrade performance (hangers and supports were operable, housekeeping, etc.) and inspected the interiors of electrical and instrumentation cabinets for debris, loose material, jumpers, evidence of rodents, et The inspectors verified thit valves, including instrumentation isolation valves, were in proper position, power was available, and valves were locked as appropriate. The inspectors compared both local and remote position indication Several deficiencies were identified, such as equipment tags missing, oil leaking from limitorques and valves needing some type of preservatio Responsiveness by operations to these items was prompt and positiv No violatiors or deviations were identifie . Onsite Followup of Events and Subsequent Written Reports (92700, 93702) On June 7,1988, with the plant in mode 3 the licensee was notified by the architect engineer for V. C. Summer Nuclear Station that a design defect may yield the potential for steam propagation, which could affect the safe shutdown of the plant under certain postulated steam event Direct steam paths through floor penetrations and more tortuous propagational paths were identified. Upon verification of the potential problem the licensee changed operational modes from mode 3 to mode 4 The licensee opened several interior plant doors to allow for the relief of pressure build-ups. One door was sealed to prevent moisture intrusion in the event of the postulated steam brea .
| |
| .
| |
| | |
| The licensee is performing further evaluations of this potential problem to insure that adequate corrective actions are in place for short and long term operation For furthee information see LER 88-008, dated July 7, 1988. This is an unresolved item, steam line rupture with potential to affect safe shutdown, 88-17-0 The inspectors reviewed the following. LER's and SPR's to ascertain whether the licensee's review, corrective action and report of the identified event or deficiency was in conformance with regulatory requirements, TS, license conditions, and licensee procedures and control Based upon this review the following items are close LER 87-11 Lots of 7.2 kV switchgear due to degraded voltage SPR 88-006 Failure of diesel fire pump to start on valid test signal SPR 86-011 keeperability of the meteorological ir.strumentation No vinlations or deviations were identifie . Action on Previous Inspection Findings (92701, 92702)
| |
| The inspectors further reviewed the July 26, 1988 reactor trip from 100*;
| |
| power, while SSPS was being tested. Subsequent to the June 1, 1988 reactor trip, while performing an SSPS logic test, the licensee made changes to STP 345.074, SSPS actuations logic and master relay test, for train "B", to insure that the breaker would be closed locally instead of from the MC Personnel failed to follow the procedure in that the breaker was closed from the MCB inst ad of locally at the RTB as specified. The solid state protection system actuation logic and master relay test for train B, STP 345.074, was initiated and channel "B" was placed in test at approximately 9:00 a.m., on July 26, 1988. A reactor trip occurred at 9:24 a.m. At approximately 4:30 p.m. , a relief shif t supervisor entered the control room and discovered that SSPS train "B" was still in tes The channel was returned to normal at approximately 5:30 STP 345.074, precaution step 3.9 limits the time that a channel may be bypassed for testing to two hours. The procedure was not followed in that operations allowed the SSPS train "B" to remain in bypass for over eight hours. During the time "B" train was in test no protection signal could have been generated by that channel. Step 3.10 of the above procedure also requires that if the test was terminated prior to
| |
| :ompletion it must be returned to norma This is an additional example of the above violation for failure to follow procedures, 88-17-01. See. Report No. 50-395/88-14 and LER 88-009 for further information, 9. Design, Design Changes and Modifications (37700)
| |
| The inspectors reviewed four design changes,1.'sted belnw not previously approved by NRR, to assure that the changes had been reviewed and approved
