SUBJECT:
QUAD CITIES INSPECTION REPORT 50-254/99009(DRP);
50-265/99009(DRP)
Dear Mr. Kingsley:
This refers to the inspection conducted April 21 through May 31,1999, at the Quad Cities
i
Nuclear Power Station. The purpose of the inspection was to determine whether actitities
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, a safety-conscious approach characterized the overall conduct of activities at
Quad Cities. At the conclusion of the inspection, the findings were discussed with members of
your staff.
During this inspection period, a Unit i reactor trip occurred. The trip was caused by interactions
of the reactor water cleanup system relief valves with the scram discharge volume. Previous
problems with the relief valves lifting were not adequately addressed. Separately, some
i
operator performance problems were identified including a failure to properly position a high
pressure coolant injection valve, a surveillance test performed on the wrong unit, and a failure
to recognize core power computer problems in a timely manner.
Based on the results of this inspection, the NRC has determined that one violation of NRC
requirements occurred. Operators failed to properly position the Unit 2 high pressure coolant
injection discharge valve during performance of a surveillance test. This violation is being
treated as a Non-Cited Violation (NCV), consistent with Appendix C of the Enforcement Policy.
T; 1s NCV is described in the subject inspection report. If you contest the violation or severity
level of this NCV, you should provide a response within 30 days of the date of this inspection
report, with the basis for your denial, to the Nuclear Regulatory Commission, ATTN: Document
Control Desk, Washington, DC 20555-0001, with copies to the Regional Administrator,
Region til and the Director, Office of Enforcement, United States Nuclear Regulatory
Commission, Washington, DC 20555-0001.
