SUBJECT:
DRESDEN INSPECTION REPORT 50-237/99003(DRP); 50-249/99003(DRP)
Dear Mr. Kingsley:
On January 10,.1999, through February 26, 1999, the NRC performed an inspection at your
Dresden Nuclear Power Station. The enclosed report presents the results of this inspection.
During the inspection period, a safety-conscious approach characterized the overall conduct of
activities at the Dresden station. Operators and station personnel performed well during the
conduct of the reactor shutdown and startup evolutions to support the planned refueling outage.
The conduct of most maintenance.activities and radiological control practices appeared to have
been performed correctly. However, a number of out-of-service errors occurred during the
outage. Further, initial corrective actions taken to address the errors were not effective in
stopping them.
While operators performed well during the conduct of routine and outage activities, we noted a
number of challenges that arose during the period. In five separate instances, actions by
station personnel resulted in the need for operators to enter unplanned Technical Specification
or Dresden Administrative Technical Requirement limiting conditions for operations. While the
limiting condition for operation action statements and time limits were not violated, each of thez
J
occurrences represented an u~necessary burden to the operators. We also noted procedural
/J
concerns which challenged the operators. These included: unclear directions in an operator
surveillance that resulted in equalizing the drywell and the torus; a high pressure coolant
injection logic test performed on-line for the first time that required revision and delayed actions
in response to control panel alarms; and an instance where operators in the control room
performed a test on the reactor building to torus vacuum breakers without having the most
recent revision to the procedure.
Based on the results of this inspection, the NRC has determined that three violations ofNRC
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 violations or severity levels of these NCVs, you
