Docket Nos.:

and 50-316

Dear Mr. Alexfch:
SUBJECT:
SAFETY SYSTEM FUNCTIONAL INSPECTION (50-315/90-201;
50-316/90-201)
We are forwarding the report of the safety
system functional inspection
(SSFI)
performed from June ll through June
22 and July
9 through July 13, 1990,
involving activities authorized
by Operating Licenses
DPR-58 and
DPR-74 for
Donald C. Cook Nuclear Power Plant, Units
1 and 2.
The Nuclear
Regulatory
Commission
(NRC) staff from the Special
Inspection
Branch of the Office of
Nuclear Reactor Regulation,
contractor
personnel,
and Region III personnel
conducted this inspection.
We discussed
the inspection findings with you and
members of your staff during an exit meeting
on July 13, 1990.
The
NRC inspection
team assessed
the operatfonal
readiness
and functionality of
the essential
(ESW) system
and interacting
systems.
The team
inspected
the areas of design,
design control, operations,
maintenance,
and
surveillance
and testing of the applicable
systems.
The SSFI
team determined
that the
ESW system
had
an adequate
design capacity to perform its required
safety functions.
Nevertheless,
problems requiring management
attention were
identified in several
areas
evaluated
by the team.
The inspection
team was
particularly concerned that the input into design calculations for the
system
was not supported
by sufficiently detailed or appropriate
independent
design verifications. It appeared
that your staff had not adequately
assessed
the safety significance of design calculation deficiencies,
determined the need
for additional verification of design calculations,
and
had not initfated
prompt corrective actions.
These. concerns
are summarized in the Executive
Summary of the enclosed
inspection report.
The inspection findings, which are discussed
in Section
2 of the report, indi-
cated that certain activities were apparently
not conducted in full compliance
with NRC requirements.
The
NRC Region III staff will review these
items
described
in the enclosed
inspection report to determine the need for any
enforcement action or other actions.
