SUBJECT:

QUAD CITIES INSPECTION REPORT 50-254/98017(DRP);

50-265/98017(DRP)

Dear Mr. Kingsley:

This refers to the inspection conducted September 2 through October 14,1998, at the

Quad Cities Nuclear Power Station. The purpose of the inspection was to determine whether

activities authorized by the license were conducted safely and in accordance with NRC

requirements. The NRC conducted routine resident inspections in this period. Based on the

inspectors' findings, overall performance at the Quad Cities station was safe. At the conclusion

of the inspection, the findings were discussed with your staff. TPe inspectors found significant

room for improvement in maintenance and out-of-service activities.

During the period, equipment problems and several maintenance and out-of-service activity

errors had a significant impact on plant operations. Errors on Unit i led to the third reactor trip

in about 3 months.' Problems stemming from preventive maintenance deficiencies led to Unit 2

reactor water level oscillations which approached the predetermined manual trip point.

Problems with the 2B reactor recirculation pump seal required a maintenance outage and the

third replacement of the seal since shutdown from the last operating cycle in February 1997.

Operators performed well at the controls during a number of operational transients. However,

operator lack of sensitivity to equipment problems and poor performance in taking a flow

transmitter out-of-service were considered weaknesses.

No cited violations of NRC requirements were identified.
