Mr. J. S. Perry
Site Vice President
Dresden Station
Commonwealth Edison Company
6500 North Dresden Road
Morris, IL 60450
Dear Mr. Perry:
Enclosed for your review is the Systematic Assessment of Licensee Performance
(SALP) 14 Report for the Dresden Nuclear Power Station, covering the period March 19,
1995, through December 28,1996. This report will be discussed with you at a public
meeting to be held at the Dresden Training Facility, at 10:00 a.m. (CST) Friday,
February 21,1997.
During this meeting you are encouraged candidly to discuss any comments you may have
regarding our report. While this meeting is considered a presentation and discussion forum
,
'
betweeri Commonwealth Ediscn Company and the NRC, the meeting will be opened to any
i
other interested parties as observers. In accordance with NRC policy, I have reviewed the
recommendations from the SALP Board assessment and concur with their ratings. The
i
functional areas of piant operations and plant support were rated Category 2; maintenance
1
and engineering areas were rated Category 3. The current SALP ratings reflect an
improved performance in plant operations and with some performance decline in
j
maintenance and surveillance activities. It is my view that the conduct of nuclear activities
in connection with the Dresden facility was adequate and overall performance continues to
)
improve.
l
During the previous (SALP 13) assessment period, performance was cyclical and was
declining near the end of the period. The efforts to reinvigorate your improvement
j
initiatives during the SALP 14 period resulted in overallimproved performance. During the
assessment period, you continued to utilize the "Dresden Plan" to focus on problem areas.
One of these focus areas, conduct of operations, achieved significant improvement.
improvements noted in the operations area resulted from implementing effective
performance standards and improved procedural adherence by control room operators.
Strong management support of conservative decision making was clearly demonstrated
during the assessment period when, on several occasions, operating units were shut down
or remained shut down until root causes and corrective actions were implemented for
<
equipment problems. While significant sustained improvements were demonstrated by
control room operators, operations performance outside the control room has not yet
i
achieved the same level of success.

Many improvements in plant material condition were made over the assessment period
during extended maintenance outages including upgrades to the feedwater level control
system, installation of the station blackout modifications, and replacement of the Unit 2
'
'
reactor water cleanup system piping and heat exchanger. However, overall plant
performance continued to be challenged by persistent weaknesses rooted in material
,
j
condition, work control, test control, and the quality of some maintenance activities.
Equipment performance problems for important systems and components, such as the high
pressure coolant injection system, the safety-related 4kV circuit breakers, the feedwater
,
j
system, and the control room emergency ventilation system led to forced shutdowns, plant
transients, and reduced safety system availability and reliability. Additionally, significant
.
l
deficiencies were identified in the surveillance and test programs this assessment period.
j
These deficiencies, along with the continued problems in material condition, work control,
!
and quality of some maintenance activities, led to the Category 3 rating in Maintenance.
l
The overall quaiity of engineering support to plant operations improved, particularly support
from system engineers. Positive initiatives included improving plant system engineers'
'
capabilities, and focusing resources to improve material condition and reduce engineering
backlogs. However, some significant errors in maintaining the design basis of the
containment cooling service water system and in the adequacy of a number of plant design
basis calculations were identified. Other weaknesses, such as the inconsistent quality of
engineering work, the inability to resolve some long-standing design problems, and the lack
'
of aggressive resolution of some nonconforming conditions until prompting by the NRC, led
to the Category 3 rating in Engineering.
Good performance in chemistry, emergency preparedness, and fire protection, and
i
improved performance in the control of personnel exposures and contaminated areas
indicate some success with your improvement initiatives in the area of Plant Support.
i
However, continued examples of radworker performance deficiencies were observed during
this assessment period.
You are requested to respond in writing within 30 days after the SALP meeting, specifically
addressing corrective actions planned to improve your performance in the areas of
maintenance and engineering. You should also be prepared to discuss our assessments
and your plans in these areas, as well as your plant performance expectations during the
SALP meeting.
