.SUBJECT:
DRESDEN INSPECTION REPORT 50-237/99011(DRP); 50-249/99011(DRP).
Dear Mr. Kingsley:
From May 22 to June 24, 1999, the NRC performed an inspection at your Dresden Nuclear
Power Station. The enclosed report presents the results of this inspection. The inspectors
identified no cited violations during this inspection period.
During the inspection period, the overall conduct of activiti_es at the Dresden station was
characterized by a safety-conscious approach. Operations, maintenance, engineering, and
plant support activities were generally acceptable.
Continuing a theme from previous inspection reports, the material condition of both units, even
though much improved, continued to affect smooth operations throughout the period. Most
significantly,* the control room ceiling was not watertight. Water from a leak in heating coils for
the turbine building ventilation system leaked into the control room, and onto the front control
panel. The water damaged some nonsafety-related chart recorders and nonsafety-related
digital indications. Also, one of the Unit 3 emergency diesel generator's heat exchangers
developed a leak. The diesel had to be inoperable to perform the repair. During the repair, the
replacement heat exchanger was found cracked after installation.
The inspectors reviewed fourteen older licensee event reports during this inspection period.
Based on the results of these reviews, the' NRC has determined that six violations of NRC
requirements occurred. All six of these violations are being treated as Non-Cited Violations,
\\
consistent with Appendix C of the Enforcement Policy. These Non-Cited Violations are
.
described in the subject inspection report. However, these Non-Cited Violations are not
described in the Executive Summary and will not be entered into the .Plant Issues Matrix
because they are greater than two years old. If you contest the violation or severity level of
these Non-Cited Violations, 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, 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 .
