Monthly' Maintenance Observation (62703) i i ' Station maintenance activities of safety-related systems and compor,ents 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 TS. Items' considered during the review < included: verification that limiting . conditions for operations were met " while components or systems were - removed from service; approvals were obtained prior to initiating the work; approved procedures were used; ] completed work was inspected as applicable; 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; and, radiological and fire prevention controls were implemented. Work requests were also 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 maintenar activities were observed / reviewed: 1-M-014 Unit 1 Lubrication Manual 2-M-014 Unit 2 Lubrication Manual 0-MP-14.1 COLT Model PC-2V Diesel Engine 18 month inspection - Diesel Generator 2B 2-GMP-52.2 Auxiliary Building monthly battery inspection MWR 138285 Replace 2" and under service water piping to RHR Pump 2B room cooler MWR 146485 -Install stainless steel bolts and nuts on RHR room cooler 1A MWR 170691 Replace Charcoal filter trays in Train 2A Penetration Room Ventilation System MWR 17843 Replace diaphram and reset automatic sprinkler system valve 1A 132 No violations or deviations were identified. a. Lubrication Program A review was made of the licensee's plant lubrication program for safety related components. Procedure 0-AP-28, Plant Lubrication Program describes the implementation of the plant lubrication --- -. --- - .- .. e
l. ,' . . 3 program. This Lincludes the valves, pumps and motors which are lubricated - by the operations group. A sample of components was selected- by the inspectors and the vendor manual ~ for each component was reviewed to verify that the lubricant and frequency specified by the plant's "Lubrication Manuals" met the vendors recommendations. ~ Records were reviewe'd to ascertain .if the ' lubrication of 'the components .was up to date. _ Lubr,1 cation of chargina pump 2A was ~ witnessed. The components reviewed were as_follows: RHR Pumps 18 and 28 CTMT Spray Pumps 1A and 2A HHSI/CVCS Pumps 1A and 2A Boric Acid Pumps 1A and 2A Auxiliary Feedwater Pumps 1A and 2A Reactor Makeup Water Pumps 1A and 2A Service Water Pumps 1C and 2C Component Cooling Water Pumps 1A and 2A MOV 8000 B from pressurizer - Units.1 and 2 MOV 8702A from RCS to RHR - Units 1 and 2 MOV 8809B RWST to RHR - Units 1 and-2 MOV 8820A CTMT Spray Pump Discharge - Units 1 and 2 MOV 8808A Accumulator Tank Discharge - Units 1 and 2 MOV 37664B Auxiliary Feedwater Discharge - Units 1 and 2 , MOV Service Water "B" Train strainer Inlet Isolation - Units 1 and 2 MOV 3185A CCW Valve Control - Units 1 and 2 The lubricant for a number of the motor operated valves (MOV) is required to be Exxon Nebular EPO. However, another lubricant has previously been used in these M0V's. This problem is addressed in NRC report' Nos. 348,364/87-15 and 87-20. Subsequently, the licensee has initiated an evaluation to determine which MOV's. should use 'the Nebular type lubricants. The results of the licensee's evaluation will be used to determine the' type lubrication to be used in the remaining MOVs. The NRC is to be advised of the results of this evaluation. Presently, the Lubrication Manuals require a 300 SSU at 100 F lubricant (Regal R&O 68) for the charging pump (HHSI/CVCS) radial and thrust bearings. But, the vendor's manual (Pacific Pumps) recommends the use of a 150 SSU at 100 F (Regal R&O 32) lubriedant. The licensee evaluated this discrepancy and contacted the vendor to determine the type lubricant that should be used. The vendor advised the licensee by letter dated July 12, 1988 that the lubricant presently being used was satisfactory for this application. L Therefore, the inspectors had no further questions on this item. _ , - _ . , .. .. _ _ . _ -

Repairs to Unit 1 RHR Room Cooler IA On April 14, 1988 RHR room cooler 1A was removed from service by MWR 146485 to replace existing staybolts and nuts with stainless steel bolts and nuts. This rework required removal and replacement of portions of ' the piping and the cooler cover plate. Upon completion of' this work, on April 18, 1988 the system was required to be hydrostatically tested. However, this requirement was not listed on the MWR and the system was not hydrostatically tested. On July 5, 1988, during a mechanical maintenance review of MWR 146485, this discrepancy was identified by the licensee. The Room Cooler was declared inoperative and the system was hydrrstatically tested and restored to service on July 7. Since this protdem was identified by the licensee and corrective action promptly initiated, in accordance with 10 CFR 2, Appendix C no violation is being cited. 4. Operational Safety Verification (71707) The inspectors observed control room operations, reviewed applicable logs and conducted discussions with control room operators during the report period. Also, the operability of selected emergency systems was verified, tagout records were reviewed and proper return to service of affected components was verified. Tours of the auxiliary building, diesel building, turbine building and service water structure were conducted to observe plant equipment conditions, including fluid leaks and excessive , vibrations and general housekeeping ef forts. The inspectors verified compliance with selected limiting condition for operation (LCO) and results of selected surveillance tests. The verifications were accomplished by direct observation of monitoring instrumentation, valve positions, switch positions, accessible hydraulic snubbers, and review of completed logs, records, and chemistry results. The licensee's compliance with LCO action statements was reviewed as events occurred. l The inspectors routinely attended meetings with certain licensee l. management and observed various shift turnovers between shift supervisor, l shift foremen and licensed operators. These meetings and discussions provided a daily status of plant operations, maintenance, and testing ' activities in progress, as well as discussions of significant problems. a. Document and Drawing Control I The inspectors reviewed 12 controlled drawings in two system operators' office spaces on the 100' and 121' elevations of the radiation area of the auxiliary building and six drawings in the system operator's office space in the diesel generator building. The drawings in the diesel building were up to date but one drawing in each auxiliary building office space was not up to date. When told of this problem the licensee immediately conducted an audit of all drawings, procedures and manuals assigned to the operations group. Several additional discrepancies were identified. All out of date l l l ' _ _ _ _ _ _ _ _ _ - - - _ _ _ _
c ^ (- ' . , . 5 -drawings, procedures and manuals were_ brought up to date. Appropriate action is being initiated to . assure that controlled documents will be maintained. This problem is considered another example of violation 348, 364/88-05-01 to which the licensee responded on June 15, 1988. Corrective action is scheduled to be. completed by November 1,1988. Therefore, another violation is not being issued. b. Fire Protection Tanks Fill Valves During a tour of the fire protection pump house the inspectors noted that the valves on the fill pipes to the fire protection storage tanks were open with the locks and chains removed from the valves. An investigation was made to determine if the valves were required to be locked in the open position. This investigation revealed that these valves were not listed on a surveillance procedure to . verify correct alignment. The licensee promptly revised procedure 0-SOP-60.1 to include these valves. These valves are not included in the TS, but the available tank instrumentation and alarms should have prevented the water level in the tanks from reaching the TS action statements. Therefore, this discrepency has little safety concern and no violation is being issued. , c. Combustible Storage in Penetration Room Filtration Filter Room On June 17, 1988 during a routine inspection of the auxiliary building a total of 18 charcoal filter elements were found stored in the penetration room filtration room. Subsequent investigation indicated that these filters had been removed from the ventilation system on April 22, 1988 but had not been removed from the ~ building as required by procedure 0-AP-35, General Housekeeping and Cleanliness Control, Section 5.1. Procedure 0-AP-52, Equipment Status Control and Maintenance Authorization, Section 7.5.6 requires that a work sequence with appropriate delineation of the work activities to be performed be included on the maintenance work request (MWR). This includes special housekeeping items. MWR 170691 required that the charcoal filters in the Unit 2 penetration room filtration system be replaced but did not specify that the old filters were to be removed and that special housekeeping requirements were applicable. The failure to specify the special housekeeping requirements and promptly remove these filter units is identified as Violation 364/88-23-01. 5. Radiological Protection Program (71709) Selected activities of the licensee's Radiological Protection Program were ' reviewed by the inspectors to verify conformance with plant procedures and NRC regulatory requirement. The areas reviewed included: organization and management of the plant's health physics staff, "ALARA"
_ _ _ _ _ _ _ _ - _ . _ _ __ _ Q 4 ., . , 6 -implementation, Radiation Work Permits (RWP's) for compliance to plant procedures, personnel exposure records, observation of work and personnel in radiation areas to verify compliance to radiation protection procedures, and control of radioactive materials. No violations or deviations were identified. 6. Physical Security Program (71881) Licensee's compliance to the approved security plan was reviewed by the inspectors. The inspectors 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: organization of the security force, establishment and . maintenance of gates, doors, isolation zones, access control, and badging procedures. No violations or deviations were identified. 7. Licensee Event Reports (92700) The following Licensee Event Report (LER) was reviewed for potential generic problems to determ'.ne 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 appropriate. The Licensee action was reviewed to verify that the event has been reviewed and evaluated by the licensee es required by the Technical Specifications; that corrective action was taken by the licensee; and that safety limits, limiting safety setting and LCOs were not exceeded. The inspector examined the incident report, logs and records, and interviewed selected personnel . The following report is considered closed: Unit 1 (348) 88-16 Special Report: Fire Door Inoperative for More Than Seven Days. No violations or deviations were identified. - 8. Engineered Safety Systems Inspections (71710) 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 verification. 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 used. The systems were assessed to be cperable in accordance with technical specifications, appropriate drawings, procedures, and the Final Safety Analysis Report. _ _ -. _ _ _ _ _ _ . _ . _ - .
