QC inspection points were established where required, (3)
required administrative approvals and tagouts were obtained prior to work initiation, and (4)
replacement parts and materials used were properly certified. The inspectors verified that these activities were accomplished by qualified personnel using the controlled copy of SP-52 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 plant performance was not developing on a given syste The inspectors observed the final stages of the "A" Emergency Diesel Generator starting air dryer piping installation as prescribed by Maintenance Work Request and Authorization Form # ENG-02 The inspectors determined that required administrative approvals and tagouts were obtained prior to work initiation. During the review, the inspectors noted that copies of maintenance work requests and authorization forms which are generated by organizations other than the Operations Department are not maintained in the control room, but are available to control room operators upon request by the Shift Foreman to the organization which generated the maintenance request. However,
plant procedures properly require that the Operations Department issue clearances and control the removal and restoration of safety related equipment. These administrative features will be inspected in more detail during future maintenance activity observation Within the areas inspected, no violations or deviations were identifie.
ESF System Walkdown (71710)
During the period of July 25 to 26,1985, the inspectors verified the operability of the engineered safety features (ESF)
system by performing a walkdown of the accessible portions of the safety injection, residual heat removal and containment spray systems as prescribed by Operations Surveillance Test Procedure OST-158 (Revision 2) titled "Safety Injection and Containment Spray Systems Flowpath Verification Monthly Interval (At Power)."
The inspectors confirmed that the licensee's system lineup procedures matched plant drawings and the as-built configuratio Minor drawing discrepancies noted by the inspectors were discussed with the licensee and actions necessary to correct these deficiencies have been established. The inspectors looked for equipment conditions and items that might degrade performance (that hangers and supports were operable, acceptable housekeeping, etc.).

to ascertain that the onsite review functions were conducted in accordance with Technical Specifications (TS)
and other regulatory requirements. The inspectors (1) attended the regular monthly PNSC meeting held on July 17, 1985 as non-participants and observed the conduct of the meeting; (2) ascertained that provisions of the TS dealing with membership, review process, frequency, qualifications, etc.,
were satisfied; (3)
reviewed meeting minutes to confirm that decisions and recommendations were accurately reflected in the minutes; and (4)
followed up to independently confirm that recommended corrective actions were complete HBR2 Post Trip and Safeguards Review As reported in Inspection Report 85-18, the Onsite Nuclear Safety (ONS)
organization provided an outstanding presentation and assessment of the results of its HBR2 Post Trip/Safeguards Actuation Review stud The ONS written materials distributed at the June 19, 1985 meeting were reviewed in detail by the inspector The hand-outs emphasized the following two specifics: To provide feedback to the plant of information ONS gleaned from the plant reactor trip history; and,
8 To present the results of an ONS evaluation of the plant trip review progra ONS expressed the objective of these two efforts to be to "Encourage plant commitment to a more dedicated and visible program for reactor trip and safeguards actuation reduction".
The ONS evaluation displayed the trip data in a variety of ways designed to characterize past performance history and to identify the trip frequencies associated with a number of contributory classe These statistics were then compared with typical industry average ONS then recommended the following: Implementation of an aggressive and proactive reactor trip and safeguards actuation reduction program including: Designation of a cognizant authority Development of a work plan Monitoring and periodic evaluation of the trip data base by ONS and plant organizations Improvements in Event Records Keeping to ensure: Improved continuity of plant records Centralization of background information files Increased detail of documentation The second item,
"ONS evaluation of the plant trip review program",
was an ONS assessment which considered the adequacy of the associated procedures and the degree to which root causes are completely established and documente ONS evaluated plant records for nine reactor trips which occurred between January 1, 1984 and March 31, 198 Discussions were also held by ONS with appropriate plant personnel to obtain sharper insight into the conduct and documentation of the plant reactor trip review This ONS effort included a comprehensive and detailed review of each of the nine trips and the ONS report documented the findings in a cogent and succinct manne The report contains a number of clearly identified observations which can be directly used to define an improvement progra In overview, ONS concluded that "Additional specifics should be added to the post-trip review documentation, including more complete documentation of programmatic followup to reflect the thoroughness with which trips are being reviewed and recurrence eliminated."
In a subsequent conversation, the Plant Manager expressed appreciation for the ONS effort and stated that a reactor trip reduction program will be implemente The inspectors will continue to monitor these activitie Within the areas inspected, no violations or deviations were identifie.
