This inspection of maintenance activities was to determine whether the licensee's maintenance program was being implemented in accordance with regulatory requirements and to determine the effectiveness of the maintenance program on important plant equipmen To achieve the above objectives, the inspector reviewed the plants'
operating history, interviewed cognizant plant personnel and selected four completed maintenance activities which fit the following categories:
-
A safety-related equipment failure leading to a plant shutdown
-
A nonsafety-related equipment failure leading to a plant shutdown
-
An equipment failure leading to reduced capability of a safety related system
-
A recurring safety-related equipment failure
The components selected by the inspector, the mechanism that provided the indication of the impending failure and the work requests (WRs)
that evaluated and corrected the failures are listed below:
-
Unit 3, Reactor Coolant Pump (RCP)
"B-1" (Component Manufacture Bingham), Operational Abnormality, WR-03321C WR-54582E and WR-573990
-
Unit 1, Main Steam (MS) Isolation Valve "155" (Component Manufacture
- Crane/Gate Valve), Operational Abnormity, WR-11699C, WR-20482C and WR-050330
-
Unit 1, High Pressure Injection Pump (HPIP) "C" (Component Manufacture -
Ingersoll-Rand) Surveillance Test, WR-19876C
-
Unit 2, Motor Driven Emergency Feedwater Pump (MDEFWP) "2-A" (Component Manufacture -
Bingham),
Surveillance Test, WR-14291C, WR-14294C, WR-92432C and WR-92921C a. Review of Records The inspector reviewed records associated with the WRs for the maintenance activities selected above to ensure the following:
(1) Required administrative approvals were obtained before initiating the wor (2) Limiting conditions for operation were met while the component or system was removed from service (3) Approved procedures were used where the activity appeared to exceed the normal skills possessed by qualified maintenance personne (4) Inspections were made in accordance with. the licensee's requirements and quality control records are complet (5) Functional testing and calibrations, as necessary, were completed before returning the equipment to servic (6) The personnel who performed the test were qualifie (7) When the activity was performed by an outside contractor, the contractor was controlled in accordance with the licensee's approved quality assurance progra (8) The licensee evaluated system failures and reported them in accordance with 10 CFR 50.7 (9) Corrective and preventive maintenance records were assembled and stored as part of the maintenance histor (10)
The measuring and test equipment was identified and in calibratio (11)
Parts and materials used were identified and at least met the specifications of the original equipmen (12)
Special processes were controlled and documente (13)
System lineups were made and verified prior to return to servic To verify the completeness of the above records, the inspector reviewed the licensee's Station and Maintenance Directives, the Maintenance Employee Training Qualification System Manual, maintenance procedures, work requests, evaluation reports, Project Services Manual, Maintenance Materials Manual and vendor manuals for the specific equipment selected for this audi During the inspector's review of the licensees maintenance directives, acronyms and initialisms were noted that were not defined in the procedure In addition, the inspector also noted in procedure 3.2.10, "Exempt Change Program", that "exempt change" was never defined. When the inspector sought assistance from cognizant planning and scheduling personnel in defining the meaning of the abbreviations or phrases the inspector discovered that these individuals also had difficulty in correctly identifying their meaning. As the audit proceeded, many of the acronyms and initialisms became common and were defined in other documents. However, since licensee personnel also had problems with some of the acronyms and initialisms, the licensee should review the procedures for clarity and determine if personnel intimately involved with using these procedures are knowledgeable of the acronyms and initialisms or whether a change is needed to the procedur This item was reported to the licensee as an, Inspector Followup Item 50-269,270,287/

Machinery History Records The inspector reviewed the machinery history records for each of the completed maintenance activities selected for this audi This information in a computer program which is updated daily if require The inspector discussed the program with the cognizant planner, requested information regarding various components and observed how quickly vast amounts of data could be retrieved, trended, and hard copy provided upon reques Instrument Calibration The inspector reviewed the calibration records for measuring equipment used in each of the maintenance activities listed below:
Maintenance Activity Measuring Device RCP "Bl" Torque Wrench 27357 MS-155 Torque Wrench 27332 and Multiplier 125K HPIP "C" Dial Indicator 26963 and Reference Standard (Dial Indicator) 26947 MDEFWP "2A" Torque Wrench 27888 and Multiplier 122K For the measuring devices listed above, the inspector reviewed the instruments calibration history, determined whether calibration reference standards were traceable to national standards, and reviewed procedures required for calibration of the instrument In addition, the technician performing the calibrations demonstrated how each tool was calibrated and controlle Review of Preventive Maintenance (PM) Program The inspector reviewed the licensee preventive maintenance program to determine the following:
