INSPECTION
REPORT 50-275/94-24;
50-323/94-24
(NOTICE OF
VIOLATION)
This refers to the inspection
conducted
by M. Tschiltz,
and the inspectors
identified in the enclosed
report, of this office on September
1 through
October
15,
1994.
The inspection
included
a review of activities authorized
for your Diablo Canyon Nuclear
Power Plant,
Units
1 and 2, facility.
At the
conclusion of the inspection,
the findings were discussed
with members of your
staff identified in the enclosed report.
Areas
examined during the 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.
The purpose of the inspection
was to determine
whether activities authorized
by the license
were conducted
safely
and in
accordance
with NRC requirements.
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
a power panel
switch which was not
in the required position
and is of concern
because it was identified by the
NRC and involved alignment of vital power to
a safety-related
system.
Two violations are not being cited.
The first violahion involving the
centrifugal
charging
pumps is not being cited because
the criteria in
Section VII.B.2 of Appendix
C to
10 CFR Part 2 of the NRC's "Rules of
Practice,"
were satisfied,
The second violation, involving improper alignment
of the residual
heat
removal
system during surveillance testing,
is not being
cited because
the criteria in Section VII.B.1 of Appendix
C to
of NRC's "Rules of Practice"
were satisfied.
The first involved actions
which
resulted
in both centrifugal
charging
pumps
being
made inoperable
in Mode
4
when Technical
Specifications
required that
a minimum of one
pump remain
25u004
94ii280037.94iii8
ADOCK 05000275
8
Z I-0
'4
operational.
The second
involved the failure to properly align the residual
heat
removal
system according to procedure
during
pump testing.
Although
10 CFR 2.201 provides for a written statement
of explanation to this
office within 20 days of your receipt of this Notice,
we note that this
violation had
been corrected
and those actions,
including your root cause
analysis,
were reviewed
and found acceptable
during this inspection.
Therefore,
no response
with respect
to this matter is required.
In accordance
with 10 CFR 2.790 of the
NRC's "Rules of Practice,"
a copy of
this letter
and its enclosures 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,
Enclosures:
