INSPECTION
OF DIABLO CANYON UNITS
1
AND 2
This refers to the routine inspection
conducted
by H. Wong,
M. Miller, W. Ang,
and
B. Olson during the period of September
2 through October 9, 1991.
This.-
inspection
examined your activities
as authorized
by
NRC License
Nos.
and
At the conclusion of the inspection,
discussions
of their
findings were held
on October 9,
1991, with Mr. J.
D. Townsend
and other
members
of your staff.
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.
Two non-cited violations of
NRC requirements
were identified
as
a result of
this inspection.
These non-cited violations
and four other events
described
in paragraph
5 of this inspection report were caused
in part by personnel
errors which were not detected
by current Diablo Canyon verification methods.
The number of errors
which have occured in the past,two
months
appears
high,
even considering
the ongoing refueling outage
in Unit 2.
Current guality
Assur'ance
trending mechanisms
do not appear to provide timely feedback
on
these
types of developing trends.
The issue of personnel
errors
had also
been
raised in General Office Nuclear Plant Review and Audit Committee
(GONPRAC)
meetings
in July and September
1991.
While some managers
have initiated
corrective actions in response
to these
most recent
personnel
error events,
an
overall site strategy to address
this problem has not been established.
Additional management
attention
appears
warranted to effectively address
this
matter.
