Monthly Maintenance Observation (Units 1 and 2)
Station maintenance activities of safety-related systems and components listed below were observed / reviewed to ascertain that they were conducted in accordance with approved procedures, regulatory guides and industry codes or standards and in conformance with technical specifications.
The following items were considered during this review:
the limiting conditions for operation were met while components or systems were removed from service; approvals were obtained prior to initiating the work; activities were accomplished usina approved procedures and were inspected as applicable; functional testing a.vi/or calibrations were perfonned prior to returning components or systems to cervice; quality control records were maintained; activities were accomplished by qualified personnel; parts and materials used were properly certified; radiological controls were implemented; and, fire prevention controls were implemented.
Work requests were reviewed to determine status of outstanding jobs and to assure that priority is assigned to safety-related equipment maintenance which may affect system perfonnance.
The following maintenance activities were observed / reviewed:
Job Order 1-5506-80-8, Repair CV-3807 Job Order 1-3933-80-8, Clean Service Water Pump Discharge Strainers Job Order 2-3182-80, Install DCR 80-0-2174 on 2K3 (2P7A turbine)
Job Order 2-7413-80-10, Correct cause of trip of 2P7A Job Order 2-2104-80, Repair "B" HPSI Pump Following completion of maintenance on the service water pump discharge l
strainers and the steam driven emergency feedwater pump, the inspector verified that these systems had been returned to service properly.
While the "B" High Pressure Safety Injection (HPSI) pump was out of service for maintenance, the inspector checked valve positions and power supplies to verify the operability of the "C" HPSI pump. Three problems were identified during the effort.
On October 16, 1980, the inspector observed that manual valve 25W-17C was open but was not locked open as required by Attachment E of Operating Procedure 2102.01. This valve is in the service water l
return line from the seal and bearing coolers for the "C" HPSI pump.
This is an apparent item of noncompliance involving failure to adhere to an operating procedure.

.r On October 16, 1980, the inspector observed that manual valve 2SI-37 was open but not locked open. While attempting to determine the procedurally required status of this valve, the inspector found that it did not appear on system drawings and was not listed in system valve alignment checklists.
This valve, which is in the recirculation line from the C HPSI pump, was installed in November 1979 by Design Change Package 79-2036 and BWR 2-9095-79-9. The licensee's failure to update applicable drawings and procedures following this design change is an apparent failure to implement the requirements of section 5.5.2 of the QA Manual Operations.

On October 15, 1980, the inspector found that 2VUC 11B, a "C" HPSI pump room cooler, had an access panel removed.
This cooler, supplied by Loop II service water, functions to cool the "C" HPSI pump room during periods of pump operation. With the access panel removed, air flow would bypass the service water cooling coils, and the cooling unit could not perform its design function.
This condition degraded the operability of the "C" HPSI pump, resulting in an apparent item of noncompliance with Technical Specification (TS) 3.5.2.
This TS requires, when in Modes 1, 2 and 3, that two independent Emergency Core Cooling Systems (ECCS) subsystems be operable with each subsystem including one operable HPSI pump.

Exit Interview The inspectors met with Mr. J. P. O'Hanlon (Plant General Manager) and other members of the AP&L staff at the end of various segments of this inspection. At these meetings, the inspectors summarized the scope of the inspection and the findings.
