SUBJECT:
NRC
INSPECTION
REPORT 50-275/94-11;
50-323/94-11
(NOTICE OF
VIOLATION)
This refers to the routine inspection
conducted
by N. Hiller, and the
inspectors
identified in the enclosed report, of this office on Narch
20
through April 23,
1994.
The inspection
included
a review of activities
authorized for your Diablo Canyon Nuclear
Power Plant, Units
1 and 2.
At the
conclusion of the inspection,
the findings were discussed
with those
members
of your staff identified in the enclosed report.
Areas
examined during this inspection
are identified in the report.
Within
these
areas,
the inspection consisted of selective
examinations of procedures
and representative
records,
interviews with personnel,
and observation of
activities in progress.
Based
on the results of this inspection,
certain licensed activities appeared
to be in violation of NRC requirements,
as specified in the enclosed
Notice of
Violation (Notice).
The violation involved the repair of a leak in the
Unit 2 reactor coolant system.
The repair evolution was not properly
controlled, resulting in the injection of argon
gas into the Unit 2 reactor
coolant system,
which could have
caused
short-term elevated radiation levels
in the reactor coolant system.
The overall
area of procedural
compliance
and the associated
implementation of
management
expectations
continues
to be
an area of our concern.
We are
concerned
that
some
members of your staff may not be fully sensitive to the
need to pay close attention to detail, to follow procedures,
and to not
proceed
in the face of uncertainty.
One example involved
a work order in
which construction
work steps
were signed off and back-dated
to the date the
work steps
were completed.
. This was not an immediate safety concern,
since
the work in the field appeared
to have
been
completed in an appropriate
manner.
These
back-dated
sign-offs were not consistent with rigorously

controlled safety work.
Additional examples
are:
(I) your refueling crew
chose to perform an operation
(lowering
a different fuel module in
location
F8)
as
a test which was not well controlled
and coordinated
and which
was not provided for in your procedure;
(2) your operations
and maintenance
organizations
chose to not implement the clearance
for repair of the safety
injection accumulator
vent line,
a violation of procedure;
and (3) your
engineering staff referenced
a test
performed several
days earlier
as the
basis for returning the reactor cavity manipulator crane to service following
relay replacement.
We acknowledge
the prompt,
aggressive
actions of both your
line and quality organizations
to identify and resolve these
problems;
however,
we encourage
you to assure that these situations
do not develop into
a trend of declining performance.
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.
After reviewing your response
to this
Notice, including your proposed corrective actions
and the results of future
inspections,
the
NRC will determine whether further
NRC enforcement
action is
necessary
to ensure
compliance with NRC regulatory requirements.
In accordance
with 10 CFR 2.790(a) of the NRC's "Rules of Practice,"
a copy of
this letter and its enclosure(s) will be placed in the
NRC Public Document
Room.
Should you have
any questions
concerning this inspection,
we will be pleased
to discuss
them with you.
Sincerely,
