Dear Mr. Kingsley:
j
This refers to the inspection conducted March 7 through April 20,1999, 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 members of your staff.
j
During the period, errors by operators and maintenance technicians resulted in a number of
conditions of low safety significance, which had the potential for greater consequences.
Electrical jumpers were connected to the incorrect 4160 Volt safety bus. A phase rotation
meter was destroyed and caused a breaker on a safety-related 480 Volt motor control center to
trip after the meter was improperly connected to the motor control center. Piping which
supported vessel level instrumentation was disconnected before another means of level
indication was established for the shut down Unit 1 reactor. Cooling water was secured to the
i
wrong reactor recirculation motor generator set, with its associated recirculation pump running.
.
Human performance errors remain a concern deserving priority attention at Quad Cities.
In addition, corrective actions from previous problems were not carried out effectively in some
cases. In one case this led to a near loss of feedwater event involving a diversion of about
25,000 gallons of centaminated condensate water through the backwash receiving tank and
onto the turbine building floor. Two similar events in 1992 led to corrective action plans which,
had they been carried out, could have prevented this event.
Based on the results of this inspection, the NRC has determined that three violations of NRC
requirements occurred. These violations are being treated as Non-Cited Violations (NCVs),
consistent with Appendix C of the Enforcement Policy. These NCVs are described in the
]
subject inspection report. If you contest the violation or severity level of these NCVs, 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,
