Dear Mr. DelGeorge:
.SUBJECT:
SERVICE WATER SYSTEM OPERATIONAL PERFORMANCE INSPECTION
(50-237/93008(DRS); 50-249/93008(DRS))
This refers to the service water system operational performance inspection
(SWSOPI) conducted by Mrs. Sonia D. Burgess and others of this office on March
29 through April 30, 1993.
The inspection included a review of authorized
activities for your Dresden Nuclear Power Station.
At the conclusion of the
inspection, the findings were discussed with C. W. Schroeder and members of
_your staff identified in the enclosed report.
The enclosed copy of our inspection report identifies areas examined during
the inspection.
The team assessed the service water system's (SWS)
operational performance.
In particular, the team reviewed in detail, the
SWS's design, maintenance, operation, surveillance and testing.
The team also
assessed the planned or completed actions for Dresden in response to Generic
Letter (GL.) 89-13, "Service Water System Pro bl ems Affecting Safety Re 1 ated
- Equipment," issued on July 18, 1989.
The team considered Dresden's SWS des)gn and operation, excluding the reduced
CCSW flow issue (report 50-237/92034; 50-249/92034), satisfactory. Hqwever,
the team identified a weakness with the lack of timely corrective action to
address deficiencies identified in three service water system self
assessments.
Many of the deficiencies were the same as those identified by
the NRC SWSOPI team.* Weakness were also identified in the inservice testing
program for valves in the SWS and in operator actions to verify proper local
dtesel generator operation during training simulations.
Your initial efforts to implement the guidelines of GL 89-13 were weak, and in
some cases did not meet the GL's intent.
As identified by your staff prior to
this inspection, several of your GL 89-13 commitments were not met.
Recent
program changes, coupled with new procedures addressing program weaknesses-
should ensure GL issues are properly addressed.

Although weaknesses were identified, the SWS's overall condition appeared
capable of completing the safety function required by the design basis.
Operations personnel were knowledgeable and well trained in system performance
and operation.
The reliability centered maintenance effort for the SWS was
considered thorough and beneficial in improving system preventive maintenance.
Based on the results of this inspection, the lack of testing certain valves in
your !ST program appeared to be in violation of NRC requirements as specified
in the enclosed Notice of Violation (No_tice).
You are required to respond to this letter and should follow the instructions
specified in the enclosed Notice when preparing your response.
In your
response, you should document the specific actions taken and any additional
actions you plan to prevent recurrence.
In addition, the report addresses a
number of unresolved issues and inspection followup items.
We request that
you also address each of these items along with your reply to the cited
violation identified in the enclosed Notice. After reviewing your response to
this Notice, including your proposed corrective actions and the results of
future inspections, the NRC will determine whether further NRC enforcement
action is necessary to ensure compliance with NRC regulatory requirements .
In accordance with 10 CFR 2.790 of the Commission's regulations, a copy of
this letter, the enclosures, and your response to this letter will be placed
in the NRC Public Document Room.
The responses directed by this letter and the accompanying Notice are not
subject to the clearance procedures of the Office of Management and Budget as
required by the Paperwork Reduction Act of 1980, PL 96-511. _
We will gladly discuss any questions you have concerning this inspection.
