SUBJECT:
NRC INSPECTION
OF DIABLO CANYON UNITS 1 AND 2
This refers to the routine inspection
conducted
by Messrs.
F.
Gee
and
D. Acker of this office on October
7 through October 25,
1991,
a meeting held
in the
NRC Region
V office on November 4, 1991,
and
a telephone
conference
held
.
on December
6.,
1991 regarding activities authorized
by
NRC License
Nos.
DRP-80
and
DRP-82.
A discussion
of findings was held by the inspectors
with
Mr. J.
D.
Townsend
and other members of your 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.
Our inspection identified that
a Technical Specification post accident
monitoring instrument
had failed and
gone undetected
for approximately
two
weeks.
Failure of this instrument
had also occurred in 1990
and was not
found by your routine surveillance
program.
We considered that your
surveillance
program
and root cause
evaluation of the 1990 failure were
inadequate.
We urge that management
attention
be directed into areas
where
sur vei llances
do not detect existing faults in Technical Specification safety
equipment
and to ensure that the adequacy of the surveillance
program =is
included in the root cause evaluation.
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
NRC Public Document
Room.
