Gentlemen:
This refers to the special team inspection conducted by Mr. J. F. Schapker and
others of this office during March 14 through May 14, 1990, of activities
related to the inadequata design flow through components using the shutdown
service water system for cooling water at the Clinton Power Station authorized
,
by NRC Operating License No. NPF-62 and to the discussion of our findings with
Mr. J. S. Perry at the conclusion of the inspection.
This inspection also
reviewed the licensee's actions associated with Generic Letter (GL) 89-13,
" Service Water System Problems Affecting Safety-Related Equipment".
The enclosed copy of our inspection report identifies areas examined during
the inspection.
Within these areas, the inspection consisted of a selective
examination of procedures and representative records, observations, and
interviews with personnel.
Dcring the course of this inspection, certain activities appeared to be in
violation of NRC requirements. These deficiencies concerned the Shutdown
Service Water System having inadequate flow from the ultimate heat sink to
certain safety-related components. The apparent violations, described in
Paragraphs 2.a., 2.c., 2.f., and 4. of this report, are being reviewed for
potential enforcement action.
You will be notified by separate correspondence
of our decision regarding enforcement action.
No written response is required
until you are notified of the proposed enforcement action.
In accordance with 10 CFR 2.790 of the Commission's regulations, a copy of
this letter and the enclosed inspection report will be placed in the NRC
Public Document Room.
