3 Monthly Maintenance Observation (62703)

Station maintenance activities of safety-related systems and components were observed / reviewed to ascertain that they were conducted in accordance with approved procedures, regulatory guides, industry codes and standards, and were in conformance with Technical Specification TFe following items were considered during the review: limiting conditions far operations were met while components or systems were removed from service; approvals were obtained prior to initiating the work; activities were accomplished using approved procedures and were inspected as appli-cable; functional testing and/or calibrations were performed prior to returning components .or systems to service; quality control records were maintained; activities were accomplished by qualified personnel; parts and materials were properly certified; radiological controls were implemented; and fire prevention controls were implemente Work requests were reviewed to determine the status of outstanding jobs to assure that priority was assigned to safety-related equipment maintenance which may affect system performance. The following maintenance activities were observed / reviewed:

-

Unit 2 TDAFW pump steam admission valve HV-3226 MWR 11597 and 11597 IC diesel generator "A" starting air compresso Unit 2 TDAFW pump discharge check valv C charging pump service water coole PCN-58422530-Replacement of fire protection solenoid valv IC diesel generator PCN-S-831-1459 FNP-0-MP-28.182 ammeter / voltmeter A hydrogen recombine Within the areas inspected no violations or deviations were identifie . Operational Safety Verification (71707) The inspectors observed control room operations, reviewed applicable logs and conducted discussions with control room operations during the report period. The inspectors verified the operability of selected emergency systems, reviewed tagout records, and verified proper return to service of affected components. Tours of the auxiliary, diesel, and turbine buildings were conducted to observe plant equipment conditions, including fluid leaks and excessive vibration The inspectors verified compliance with selected Limited Condition for Operations (LCO) and results of selected surveillance test The verifications were accomplished by direct observation of monitoring l

'

instrumentation, valve positions, switch positions and review of completed logs, records, and chemistry result The licensee's compliance with-LC0 action statements were reviewed as they happened.

> The inspectors routinely attended meetings with certain licensee management and observed various shift turnovers between shift super-visors, shift foremen, and licensed operator These meetings and discussions provided a daily status o# plant operating, maintenance, and testing activities in progress, as well as discussions of significant problems, The inspector verified by observation and interviews with security force members that measures taken to assure the physical protection of the facility met current requirements. Areas inspected included the organization of the security force; the establishment and maintenance of gates, doors, and isolation zones; that access control and badging were proper; and procedures were followed, A possible generic problem leading to the inoperability of certain air operated valves with Cowan or Bettis piston actuators was discovered by the licensee. On October 9, 1985 following maintennace on the Unit 2 turbine driven auxiliary feedwater (TDAFW) pump steam admission valve (HV-3234B) the valve would not operate. Inspection revealed the valve cylinder exhaust vent plug had been painted over. A new breather plug was installed and the valve operated properly. It appears, with the vent plug painted over, leaking 0-rings had allowed pressure to build up on top of the actuator piston and with the aid of spring pressure the valve would not operate. The failure of this valve did not cause the TDAFW pump to be inoperable because the parallel air operated steam admission valve was operabl . .

.

.

Within the exception of containment other air operated valves with actuators manufactured by Cowan Dynamics Limited or Bettis Corporation were inspected by the license Other valves were found to have painted over vent plugs but none were inoperable. The containment air operated valves will be inspected during the next refueling outage.on each unit. Also, the licensee

.is developing a new PM to replace vent plugs on a periodic basi . Licensee Event Reports The following Licensee Event Reports (LERs) were reviewed for potential generic problems to determine trends, to determine whether information included in the report meets the NRC reporting requirements and to consider whether the corrective action discussed in the report appears appropriat Licensee action, with respect to selected reports, were reviewed to verify that the event had been reviewed and evaluated by the licensee as required by the Technical Specification; that corrective action was taken by the licensee; and that safety limits, limiting safety setting and LCOs were no exceeded. The inspector examined selected incidents reports, logs and records and interviewed selected personne The following reports are considered closed:

.

The inspectors performed various system inspections during the inspection period. Overall plant conditions were assessed with particular attention to equipment condition, radiological controls, security, safety, adherence to technical specification requirements, systems valve alignment, and locked valve verificatio Major components were checked for leakage and any general conditions that would degrade performance or prevent fulfillment of functional requirements. The inspectors verified that approved procedures and up-to-date drawings were use Portions of the following systems were observed for proper operation, valve alignment and valve verification:

-

Auxiliary feedwater system Chemical volume control system Service water system Boric acid transfer syste Containment spray system including chemical additive syste Residual heat removal syste =

The inspectors reviewed plant electrical alignment for specific AC buses, verified line-ups were in accordance with plant procedures, and as built configurations matched plant drawings. The general condition of equipment was checked to identify any items which could degrade plant performanc The inspector compared Unit 2 electrical loads diagram (drawing D-203096 Rev. 0) with breaker name plate nomenclature and On-site Distribution

' Surveillance Test Procedure (STP) 27.2. The following discrepancies were identified: Inverter 2A, 2C and 20 AC supply breaker numbers listed on the loads diagram did not match numbers given in the STP and on the Motor Control Centers (MCC) 2A and 2B. Breaker numbers listed in the STP and on the MCC did matc '

This will be carried as an Unresolved Item *. 50-364/85-42-0 . TMI Item II B.1 - Reactor Head Vents Reactor Vessel head vents have been installed on Units 1 and The inspectors have verified that the operation of these vents is included in appropriate plant procedure . Containment Building Electric Hydrogen Recombiner On March 11, 1985 Westinghouse Electric Corporation issued Technical Bulletin TB-85-08 which addressed possible damage to the insulation of the main power cables inside the Electric Hydrogen Recombiner. The damage could consist of frayed-chaffing of the cable braiding and deterioration of the cable insulatio The vendor made various recommendations to alleviate possible inoperability of the recombine The licensee has incorporated these inspection recommendations into Surveillance Test Procedure No. 600, " Electric Hydrogen Recombiner Visual and Electrical Test". This surveillance test is scheduled to be conducted'during each refueling outag The inspector had no further question *An Unresolved Item is a matter about which more information is required to determine whether it is acceptable or may involve a violation or deviati,on.
