Attention:
Mr.
G.
C. Sorensen
Manager Regulatory
Programs
Gentlemen:
Subject:
NRC Inspection
This refers to the inspection
conducted
by Messrs.
C. J.. Bosted
and
. R.
C. Sorensen
of this office on May 14 - June 17,
1990 of activities
authorized
by NRC Operating
License
No. NPF-21,
and to the discussions
of
their findings held by the inspectors with Mr. J.
Baker and other members of
the Supply System's staff at the conclusion of the inspection.
Areas examined during this inspection are described in the enclosed
inspection
report.
Within these
areas,
the inspection consisted of selective
examinations of procedures
and representative
records,
interviews with
personnel
and observations
by the inspectors.
As discussed in paragraph
9 of the enclosed report,
an attempt to energize
the
25KV portion of the unit electrical
system
on June 3, 1990, resulted in a
major electrical fault due to the associated
electrical lines having been
inadvertently left grounded to the station ground.
We understand that you are
conducting
an assessment
of this event,
which was still in progress
at the
conclusion of this inspection,
however, preliminary results
and our own review
indicate that inadequate
grounding practices
and
a failure to follow standard
electrical practices
contributed significantly to the event.
Although the
equipment involved was not safety-related,
the procedures
used to control the
work are
common to the facility.
Therefore; you are requested
to inform this
office, within thirty days of the date of this letter, of your final
assessment
of the causes
of the event
and the actions you plan to correct
those
causes.
Based
on the results of this inspection, it appears
that one of your
activities was not conducted in full compliance with NRC requirements.
A
Severity Level
V violation was identified,
as discussed
in paragraph
9.
In
view of improvements
already
implemented to address this concern,
and pursuant
to 10 CFR Part 2, Appendix C, this item is not being cited in-a Notice of
Violation.
Accordingly, a response
to this item is not required.

In accordance
with 10 CFR 2.790 (a3,
a copy of this letter
and the enclosure
will be placed in the
NRC Public Document
Room.
Should you have any questions
concerning this inspection,
we will be pleased
to discuss
them with you.
Sincerely,
