Subject:
NRC Inspection of Diablo Canyon Units
1 and
2
This refers to the special
inspection
conducted
by H.
Wong and
P. Morrill on
March 17 through April 27,
1992,
as documented
in Inspection
Report
No. 92-17,
issued
on May 12,
1992.
This inspection
examined your activities related to
maintenance,
inspection
and operability of containment
fan cooler units
(CFCUs) for Diablo Canyon Units
1 and 2.
These matters
were discussed
during
an enforcement
conference
on May 21, during a subsequent
telephone
conference
on May 31,
and in your Revision
1 to Unit
1 licensee
event report
(LER)
No.91-019.
After review of the additional information presented
in your revised
LER and
based
on the discussions
referenced
above,
we find your conclusion that the
requirements
of CFCU Technical Specification 3.6.2.3
were not violated to
be reasonable.
Accordingly, the apparent violation regarding
CFCU inopera-
bility has
been eliminated.
However,
based
on the results of the special
inspection referenced
above,
certain of your activities appeared
to be in violation of NRC requirements,
as
specified in the enclosed
Notice of Violation (Notice).
Although CFCU
operability is no longer an issue,
we are nonetheless
concerned
about improper
maintenance
practices
which led to the inoperable
CFCU backdraft dampers,
and
the in'effective corrective actions concerning the dampers.
Your corrective
actions for these
concerns
and the organizational
deficiencies
which
contributed to them will be examined during future inspections.
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 enforcement
action is
necessary
to ensure
compliance with NRC regulatory requirements.
