DRESDEN INSPECTION REPORT 50-237/99008(DRP); 50-249/99008(DRP)
-
Dear Mr. Kingsley:
On April 8 through May 21,1999, the NRC completed an inspection at your Dresden Nuclear
Power Station. The enclosed report presents the results of this inspection. No cited violations
were identified during this inspection period.
During the inspection period, a safety-conscious approach characterized the overall conduct of
activities at the Dresden station. Activities were generally acceptable. Your staff and the
.
inspectors noted two areas that needed improvement. First, maintenance on the safety-related
emergency control room ventilation system and its supporting breakers was not performed well.
Second, several low impact issues related to communications were present in operations,
maintenance, and security.
The material condition of both power plants continued to impact smooth operations throughout
the period. Unit 3 required a Notice of Enforcement Discretion from the NRC to permit
continued operations after the combination safety / relief valve failed. The reactor water cleanup
systems on both Unit 2 and Unit 3 experienced problems which resulted in significant
perturbations to the systems. Also, a failed pump speed controller in the reactor recirculation
system on Unit 2 caused an unplanned power reduction, while the failure of a reactor
recirculation motor-generator set ventilation damper on Unit 3 required operators to reduce
power, Lastly,'at the end of the inspection period, your staff was planning to secure one
operating recirculation purnp on Unit 3 to enter single-loop operations to address an additional
material condition problem.
Based on the results of this inspection, the NRC has determined that four 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 resognse within 30 days of the date of this inspection report, with the basis for
your denial, to the Nu6 lear Regulatory Commission, ATTN: Document Control Desk,
Washington, D.C. 20555-0001, with copies to the Regional Administrator, Region Ill, and the
Director, Office of Enforcement, United States Nuclear Regulatory Commission, Washington,
D.C. 20555-0001,
