Offsite Review Committee (40701)

The inspectors conducted a review of the offsite nuclear safety review cmmittee (NSRC) to ascertain whether the offsite review functions were conducted in accordance with TS and other regulatory requirements. It was determined that review group membership and qualifications were as required; that meetings were convened when required; and the meeting frequency and quorum met applicable requirement The inspectors attended the NSRC nieeting at corporate headquarters on March 11, 198 No violations or deviations were identifie . ESF System Walkdown (71710)

The inspectors verified the operability of two engineered safety features (ESF), system by performing a walkdown of the accessible portions of the Residual Heat Removal and Reactor Building Spray Systems. The inspectors confirmed that the licensee's system lineup procedures matched plant drawings and the as-built configuration. 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, etc. The inspectors verified that valves, including instru-mentation isolation valves, were in proper position, power was available, and valves were locked as appropriate. The inspectors compared both local and remote position indication No violations or deviations were identifie . Monthly Maintenance Observation (62703)

The inspectors observed maintenance activities of safety-related systems and components to ascertain that these activities were conducted in accordance with approved procedures, Technical Specifications (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 personnel. The inspectors independently verified that equipment was properly tested before being returned to service. Additionally, the inspectors reviewed several out-standing 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:

MWR8600439 Maintenance on turbine driven emergency feedwater pump GMP100.002 turbine throttle valve overspeed tri MWR8501571 Replace gasket on the service water syste MWR8501570 MWR8501572 GMP100.002 MWR8503042 Repaired level control valve LCU01328WG on the waste gas syste MMP445.006 Maintenance of diaphragm valve MWR80M0026 Repair of damage to emergency diesel generator valve train assembly valve XE0001B MMP180.033 Emergency diesel generator 18 months maintenanc GMP100.002 MWRS50-2041 Replaced seals on the liquid waste system valves XEV0029-PP MMP320 104 Certified pump general maintenance procedur No violations or deviations were identifie . Operational Safety Verification (71707)

The inspectors toured the control room, reviewed plant logs, records and held discussions with plant staff personnel to verify that the plant was being operated safely and in conformance with applicable requirement Specific items inspected in the control room included: adequacy of staffing and attentiveness of control room personnel; TS and procedural adherence; operability of equipment and indicated control room status; control room logs, tagout books, operating orders, jumper / bypass controls; computer printouts and annunciators. Tours of other plant areas were conducted to verify equipment operability; control of ignition sources and combustible materials; the condition of fire detection and extinguishing equipment; the control of maintenance and surveillance activities in progress; the imple-mentation of radiation protective controls and the physical security pla Tours were conducted during normal and random off-hour period No violations or deviations were identifie . Fire Protection / Prevention (64704)

The inspectors conducted an inspection in the above area to determine the status and actions taken by the licensee on open items that had been identified.in Region II inspections report 395/85-2 One of the areas inspected covered the installation of thermo-lag 330 fire barrier material on cable tray 3088. This work -was accomplished under Modification Request Form (MRF) 31971 and Maintenance Work Request (MWR)

March 7, 198 A review of the MRF and MWR package against the actual installation by the inspector revealed that the final installation did not meet all requirements that were recommended and analyzed for by the vendo After noting concerns in this area the inspector requested that the licensee provide the seismic analysis that had been accomplished for the added weight on the cable trays. While awaiting this information, the licensee dis-covered that the weight of material installed on the cable tray did not match the weights used in the analysis. The analysis used a weight of 3.25 lbs/ft2 and information obtained from the manufacturer of the thermo-lag barrier material was that weight of the material provided to the licensee could be as high as 4.75 lbs/ft This deficiency led to a detailed inspection of the installation by the inspector and the licensee. Addi-tional deficiencies identified included: incorrect spacing of steel bands used to secure thermo-lag panels to the cable tray, all metal in contact with tray not insulated for 18 inches away from tray, use of wire in lieu of banding material and cracks in trowelable material. The above deficiencies were the result of the use of vendor technical notes and instructions provided with the MWR to perform the work and inspection activities asso-ciated with installation instead of developing specific work and inspection procedures to cover those activitie The above deficiencies are contrary to the requirements of 10CFR50 Appendix "B" Criteria V and the Operational Quality Assurance Plan Section 4.0 (Status Procedures) and 11.0 (Inspection)

which require that activities affecting quality shall be accomplished in accordance with procedures which contain adequate instruction to accomplish the task and provide for quantitative and qualitative acceptance criteria to determine acceptability of the completed work. This is a violation, Inade-quate Cable Tray Thermo-lag Installation, (86-07-01).

The licensee had documented the above deficiencies on nonconformance notices (NCN) Nos. 2214 and 2151. An evaluation was completed on the seismic loading of the cable trays to allow continued operation. Work is in progress to clear the above deficiencies. Other than the above, no addi-tional violations or deviations were identifie . Other Areas:

The inspectors observed the practice Emergency Plan exercise conducted on March 26, 1986. This exercise was in preparation for an evaluated exercise that will be conducted on April 9, 198 The inspectors attended the Systematic Assessment of License Performance (SALP) presentation at Corporate Offices on March 18, 1986. R. Walker, Director, Reactor Projects, Region II and H. Dance, Reactor Projects Secticn Chief made a presentation on the current SALP to licensee management. The SALP report is found in Inspection Report No. 50-395/85-47.
