Attention:
Hr. A. L. Oxsen
Deputy Managing Director
Gentlemen:
.Subject:
NRC Inspection
This refers to the inspection
conducted
by Messrs.
R.
C. Sorensen
and
C. 0. Townsend of this office on December 3,
1990 - January
13,
1991 of
activities authorized
by
NRC Operating
License
No. NPF-21,
and to the
discussion of findings held by the inspectors
with, Hr. J.
Baker
and other
members of the Supply System staff at the conclusion of the inspection.
Areas
examined during this inspection
are described
in the enclosed
inspec-
tion report.
Within these
areas,
the inspection consisted of selective
examinations of procedures
and representative
records,
interviews with
personnel
and observations
by the inspectors.
Based
on the results of this inspection, it appears
that certain of your
activities were not conducted
in full compliance with NRC requirements,
as
set forth in the Notice of Violation, enclosed
herewith
as Appendix A.
These
violations involved insufficient corrective actions in response
to the
. May 1990 diesel
generator
bearing failure,
and performance of a surveillance
test without establishing
the specific conditions prescribed
by the Technical,
Specifications.
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.
The violation involving diesel
generator
bearing oil leakage
and monitoring
is of particular concern to us in view of the significant bearing failure and
fire which you experienced
in Hay 1990.
As discussed
in paragraph
4 of the
enclosed
inspection report,
our inspectors
identified
a low bearing oil level
condition associated
with the Division I Emergency Diesel Generator,
which
had existed since the previous
day and
was not corrected for approximately
two days after its initial discovery
by plant personnel.
Further examination
of this issue identified two previous occasions
on which oil was
added after
comparable
delays,
without appropriate tracking of oil additions to monitor
the rate of oil leakage.
Your staff also
had not established
appropriate

acceptance
criteria specifying the minimum bearing oil level required for the
diesel
generator to be considered
These observations
indicate that
your staff has not responded sufficiently to the lessons
lear'ned
from the Hay
1990 bearing failure and fire, particularly in view of the narrow range of
acceptable
bearing oil level.
In your response
to the above Notice, please
address
the actions you plan to take to effectively resolve this concern.
Based
on the results of this inspection, it also appears
that certain of your
activities did not fully meet'a
commitment
made to the
NRC,
as set forth in
the Notice of Deviation, enclosed
herewith
as Appendix B.
You are requested
to provide,a response to'his Notice, as stated in Appendix B, Notice of
Deviation.
In accordance
with 10 CFR 2.790(a),
a copy of this letter, the enclosures,
'nd your responses
will be placed in the
NRC Public Document
Room.
The responses
directed/r'equested
by this letter and the accompanying
Notices
are not subject to the clearance
procedures
of the Office of Hanagement
and
Budget
as required
by the Paperwork
Reduction Act of 1980,
PL 96-511.
Should you have
any questions
concerning this inspection,
we will be pleased
to discuss
them with you.
