SUBJECT: 'RC
INSPECTION OF DIABLO CANYON UNITS 1 AND 2
This letter refers to the Measuring
and Test Equipment
(MSTE) inspection
conducted
by Messrs.
C. Myers, and
M. Royack, of this office, and an
NRC
consultant,
M. Good,
on November 27-30,
1990,
December
17-21,
1990,
and
January 7-11,
1991 of activities authorized
by
NRC License
Nos.
DPR-80 and
d
and to the discussion of out findings held with Mr. J.
D. Townsen
and other members of your staff during the inspection periods
and
t the
conclusion of the inspection.
Areas
examined during thss
snspectson
are described
1n the enclosed
inspection repcrt.
Within these
areas,
the inspection consisted of selective
examinations of procedures
and quality records,
interviews with personnel,
field inspections of facilities, and observations
by the inspectors.
.~el
peg~ptg $
The results of this inspection indicate
a continuing weakness
in the
implementation of your quality programs for control of measuring
and test
equipment in ttIe area 0f mechanical
maintenance.
We acknowledge
your recent
effort to improve the timeliness of event-related
corrective actions.
These
actions
were discussed
at length during our management
meeting
on* October 10,
1990.
However,
we are concerned that your problem identification and
corrective action measures
%ave apparently not been very effective in dealing
with the programmatic
weakness
identified during this inspection.
Your
corrective actions in dealing with these
problems
were not considered
comprehensive
nor timely.
Your audits identified problems in this area
as
early as
1985
and
a nonconformance
report written to resolve the problems
appears
to have
been inappropriately closed, without verifying either the
accomplishment or effectiveness
of the cor rective actions .
Your staff appear s
to have
been reluctant to use the formal nonconformance
system to address
the
central
issue of ineffective corrective action, or the issue of the safety
significance of persistent
weakness
in control of MIITE.
As a result of your
staff's missed opportunity to correct
MINUTE problems in the mechanical
maintenance
area
and preclude recurrence,
our inspectors identified what
'ppear
to be continuing examples of prograIanatic
MSTE deficiencies.

Although many of the findings have involved documentation deficiencies,
additional inspection effort is planned to assess
the technical
safety
significance.
Enforcement action related to inspection of this area will be
the subject of separate
correspondence, if appropriate.
In accordance
with 10 CFR 2.790(a),
a copy of this letter and the. enclosure
will b'e placed in the
NRC Public Document
Room.
Should you have any questions
concerning this inspection,
we will be glad to
discuss
them with you.
Sincerely,
