SUBJECT:
- NRC INSPECTION
OF DIABLO CANYON UNITS
1 AND 2
This refers to the unannounced
inspection
conducted
by Mr. F.
Gee of this
office on June
3 through June
14, 1991, of activities authorized'y
NRC
'icense
Nos.
and to the discussion of our findings held
with members of your 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 inspector.
As
a result of this inspection,
we noted several
weaknesses
in the
performance of design engineering
work.
In particular,
we are concerned
that required separation
of some safety related electrical circuits may
not be properly implemented at Diablo Canyon.
You are requested
to take
prompt action to resolve this apparent
design
problem.
We encourage
continued
use of Safety
System
Outage Modification Inspections

group and timely resolution of SSOMI
findings.
No violations or deviations of NRC requirements
were identified within the
scope of this inspection.
In accordance
with 10 CFR 2.790(a),
a copy of this letter and the enclosure
will be placed in the

Room.
Should you have
any questions
concerning this inspection,
we will be glad to
discuss
them with you.
