September 27, 1984. The program set fo'rth in this procedure appeared to satisfy regulatory requirements and licensee commitment However, l the NRC inspector identified an area not addressed by the governing

-procedure. This was that specific maintenance procedures.are not referenced on the applicable "preventite maintenance cards." These

cards are the only formal means by which the Maintenance Planner assigns preventive maintenance to the various shop Notwithstanding this item, the NRC inspector concluded that

Surveillance Program

' The NRC inspector performed a brief review of the licensee's surveillance program. A more in-depth review will be accomplished at a future NRC inspection. The NRC inspector reviewed licensee surveillance procedure 6.0.1, " Surveillance Program," Revision 1,

~

March 4,'1985. The program set forth in this procedure appeared to satisfy regulatory requirements and licensee commitment Corrective Maintenance' Program The NRC inspector reviewed licensee maintenance procedure 7.0.1,

" Work Item Tracking - Corrective Maintenance," Revision 2, April 19, 1985. The program set forth in this procedure appeared to meet regulatory requirements and licensee commitments.

- The NRC inspector reviewed the following files of maintenance work requests (MWRs) to verify implementation:

,

System Year Reactor Core Isolation Cooling (RCIC).

~

1984 High Pressure Core Injection (HPCI) 1984 Residual Heat Removal (RHR) 1985 Standby Diesel Generators 1985 The NRC inspector identified some problems from this review. - These were:

(1) Leakage by the drain shutoff valve to the RHR Loop A Injection Line. The corrective action was to' cap the line downstream of the leaking valve but failed to initiate plans to repair or replace the valve. Additionally, the action that was taken showed that the system valve lineup was incomplete; it did not list the valve cap which the licensee had installed to contain the leakage. No revision to the valve lineup procedure was mad (MWR85-1887,1985)

(2) Motor burnup on the operator to the RHR system Drywell Spray Outboard Throttle Valve due to the limit switch actuating pin

having fallen out. This prevented the motor from stopping when the valve was.in the closed position. No action was taken to determine why the pin had fallen out and whether other- valves onsite had the same problem. Also, no evaluation was made to determine if the valve ~ seat had been damage (MWR85-1461, 1985)

These two examples were identified as a single apparent violation of the licensee's operations quality assurance program requirements in the area of corrective action. The licensee failed to.take adequate

, corrective actions for the above-noted conditions adverse to qualit (50-298/8527-01)
