Plant Operations Reviews (Units 1 and 2)

The inspector periodically during the inspection interval reviewed shift logs and operations records, including data sheets, instrument traces, and records of equipment malfunctions. This review included control room Jogs, auxiliary logs, operating orders, atanding orders, jumper logs and equipment tagout records. The inspector routinely observed operator alertness and demeanor during plant tours. During abnormal events, operacor performance and response actions were observed and evaluated. The inspector conducted random off-hours inspections during the reporting interval to assure that operations and security remained at an acceptable level. Shift turnovers were observed to verify that they were conducted in accordance with approved licensee procedures. The inspector had no further comments.

6.

Plant Tours (Units 1 and 2)

The inspector conducted plant tours periodically during the inspection

,

interval to verify that monitoring equipment was recording as required, equipment was properly tagged, operations personnel were aware of plant conditions, and plant housekeeping efforts were adequate. The inspector

also determined that appropriate radiation controls were properly established, critical clean areas were, being controlled in accordance with procedures, excess equipment or material is stored properly and combustible material and debris were disposed of expeditiously.

During tours the inspector looked for the existence of unusual fluid leaks, piping vibrations, pipe hanger and seismic restraint settings, various valve and breaker positions, equipment. caution and danger tags and component positions, adequacy of fire fighting equipment, and instrument calibration dates.

Some tours were conducted on backshif ts and weekends. The inspector had no further comments.

7.

Technical Specification Compliance (Units 1 and 2)

During this reporting interval, the inspector verified compliance with selected limiting conditions for operation (LCO's) and results of selected surveillance tests. These verifications were accomplished by direct obser-vation of monitoring instrumentation, valve positions, switch positions, and review of completed logs and records. The licensee's compliance with selected LCO action statements were reviewed on selected occurrences as they happened. The inspector had no further comments.

S.

Physical Protection (Units 1 and 2)

The inspector verified by observation and interview during the reporting interval that measures taken to assure the physical protection of the

' facility met current requirements. Areas inspected included the organization of the security force, the establishment and maintenance of gates, doors and isolation zones in the proper condition, that access control arid badging was proper, that search practices were appropriate, and that escorting and communications procedures were followed.

The inspector had no fUrther comments.

Review of Nonroutine Events Reported by the Licensee (Units 1 and 2)

The following licensee event reports (LER's) were reviewed for potential generic problems, to detect possible trends, and to determine whether corrective actions appeared appropriate. Events which'were reported immedi-ately were alao reviewed as they occurred to determine that technical specifications were being met and that the public health and safety was of utmost consideration.

Additional inplant reviews and discussions with plant personnel as appropriate were conducted for those indicated by an asterisk.

Cooling Water Isolated to RHR Service Water Pumps (unit 1)

During normal power operation on May 10, 1980, while performing routine surveillance activities, Residual Heat Removal, (RHR) train "B" was aligned to the torus to provide cooling while running the Reactor Core Isolation Cooling (RCIC) system. Shcrtly after placing "B" RHR service water pump (SW) in service, a motor bearing high temperature alarm was received and it was found that the cooling water to the motor bearing cooler had been isolated. Further investigation revealed that cooling was also isolated to the "A" RHRSW pump. Had these pumps been required to perform their safety function, both pumps, according to technical estimates, would have failed within I hour of operation. The pumps were last proven operable on April 8, 1980.

It is not known how the cooling water isolation valves came to be shut between intervals. The licensee took action to lock all four valves open on all four pumps on both units. This occurrence was properly reported to the NRC (LER 50-321/80-45).

The licensee failure to maintain cooling water isolation valves in the '

proper position as required by plant procedures to perform their safety function is contrary to technical specification 6.8.1, which requires that j

written procedures governing the operation of safety-related systems be implemented. This is an infraction (50-321/80-24-01).
