Dear Mr .. Reed:
This letter refers to the inspection conducted by
Mr. H. A. Walker and others of this office on September 16
through 20, 1991.
This inspection at the Dresden Nuclear Power
Station, Units 2 and 3, included an assessment and evaluation of
your support and implementation of maintenance activities.
At
the conclusion of the inspection, we discussed our findings with
those members of your staff identified in the enclosed report.
Areas examined during the inspection are identified in the
in~pection report.
Within these areas, we selectively examined
procedures and representative records, made observations, and
conducted interviews with your personnel.
As discussed in Section 3.5.1 of the report, the inspectors had
- specific concerns with the interval between scheduled preventive
maintenance tasks on the emergency diesel engine/generators.
An
inspection and maintenance interval was lengthened without a
technical evaluation despite evidence that diesel reliability may
be impaired.
This.matter is considered unresolved.
We request
that you respond within 30 days of the date of this letter with a
description of the actions you have taken or plan to take on this
matter.
No violations of NRC requirements were identified during the
course of this inspection.
In accordance with 10 CFR 2.790 of the Commission's regulations,
a copy of this letter, the enclosed inspection report and your
response to this letter will be placed in the NRC Public Document
Room.
