Operator Requalification Training

a.

Inspection Scope

On May 8, 2000, the inspector observed and evaluated portions of the licensed operator requalification training for Crew E in the plant simulator facility. The training consisted of operator proficiency in the use of substantial revisions to Emergency Operating Procedure E-0, “Reactor Trip or Safety Injection,” and RO-1, “BOP Operator Actions During Use of EOPs.” The inspector evaluated operator performance in mastering the training objectives for mitigating the consequences of plant events.

Maintenance Rule Implementation

a.

Inspection Scope

The inspector reviewed the implementation of the Maintenance Rule (MR) as related to the following topics:

  • 35 service water pump test failure on April 6, 2000

  • Containment isolation valve system performance criteria for returning the system

to MR a(2) status.

b.

Issues and Findings

There were no findings identified during this inspection.

The inspector determined that the licensee’s service water action plan to exit MR status “a(1)” was not properly updated to reflect recent service water pump test failures and performance problems. The service water system had been in MR “a(1)” status since 1996, and entered ”a(1)” status because the pumps did not start when required. The system remained in “a(1)” because of excessive pump unavailability due to accelerated degradation of pump differential pressure. The licensee determined that the degradation was caused by a higher than expected rates of impeller erosion. The licensee’s corrective actions for this degradation included a replacement of the pump shaft with an upgraded material. The inspector identified that the action plan used to remove the system from “a(1)” status did not address the current service water pump unavailability performance problems as required by Technical Support Procedure TSP- 053, “System Performance Monitoring and Trending.” The licensee indicated that the action plan would be updated by the end of July 2000.
