Dear Mr. Horn:

SUBJECT: COOPER NUCLEAR STATION (CNS) SHUTDOWN RISK AND OUTAGE
!
MANAGEMENT INSPECTION (NRC INSPECTION REPORT 50-298/93-201)
l
I am forwarding the report of the shutdown risk and outage management
inspection conducted by the U.S. Nuclear Regulatory Commission-(NRC) staff
}
from March I through March 5, and April 8 through April 16, 1993. The-
,
activities inspected were authorized by NRC Operating License DPR-46 for the
!
Cooper Nuclear Station. At the conclusion of the inspection, an exit meeting
was held where the team discussed its inspection findings with members of your
i
staff.
j
.
During the first phase of the inspection, conducted before the 1993 refueling,
~
outage, the team examined the adequacy of your outage planning with respect to
minimizing the risk of accident sequences during shutdown conditions. During
,
-
the second phase, conducted during the outage, the team examined the
implementation of your outage plan.
i
The team found that you had developed and were implementing an outage plan -
that considered the risk associated with plant shutdown evolutions. Specific
'
strengths included a reduction of overall personnel exposure during the
.
!
shutdown evolution, good operator awareness of equipment available to mitigate-
ever.ts which impact shutdown safety, and strong control over fuses removed by
'
clearances. The team also viewed your shutdown risk self-assessment review as
j
thorough, but noted that not all corrective action recommendations had been
completed.
!
i
The team identified deficiencies in your programs in the 'following' areas: (1)
'!
procedural nonadherence associated with maintenance, operations, and
administrative activities; and (2) an apparent Technical. Specification non-
1
,
compliance involving movement of the reactor vessel head and upper internals
1
over the core without an operabla secondary containment.
j
-(
Areas for potential improvement and program enhanceme'nt' include the following::
'{
(1) continued management attention to the implementation of your self-
t
assessment recommendations; . (2) more specific policy and implementation
a
-guidance for the shutdown safety program; and (3) better work planning and-
l
implementation strategies to reduce the number of events which continue to
f
impact shutdown safety functions.
