DESIGN INSPECTION
(NRC
INSPECTION
REPORT
NO. 50-397/96-201)
Dear Mr. Parrish:
During the period from November
18 through January
16,
1997, the U.S. Nuclear
Regulatory Commission's
(NRCs) Office of Nuclear Reactor
Regulation
(NRR)
performed
a design inspection of the
WNP-2 automatic depressurization
system
(ADS), standby service water
(SSW) system,
and train
B of the residual
heat
removal
(RHR) system.
The purpose of the inspection
was to evaluate
the
capability of the systems
to perform safety functions required
by their design
basis,
adherence
to the design
and licensing basis,
and consistency
of the as-
built configuration with the Updated Final Safety Analysis Report.
The results of the inspection
are contained
in the enclosed report.
Overall,
the inspection
team determined that the selected
systems
are capable of
performing their intended safety functions.
Your engineering staff exhibited
knowledge of the systems
evaluated,
including the design basis,
and provided
excellent support to the inspection
team.
One of the team's significant findings addresses
a design deficiency that
was
introduced during the modification of the
ADS, inadvertently defeating
the
intended
manual initiation of the system.. Other significant issues
involved
the
RHR heat
exchanger operability assessment
based
on data from faulty
instruments,
and the potential for exceeding
the
ADS actuator design pressure
by initiating containment
spr ay during post
LOCA elevated
containment
temperatures.
Many of the team's
findings relate to your failure to keep the
FSAR updated.
Examples are,
the
ADS wiring modification and the removal of the
SSW keepfull
pumps
from service.
Your design review documents
(DRDs) were of uneven
quality.
For example,
the
RHR document
lacked important instrumentation
and
control
(I&C) information.
Your staff has
implemented corrective actions for many of the team's findings.
Please
provide
a schedule within 60 days of your plans to complete your
corrective actions for the open items listed in Appendix A to the report
so
the
NRC staff can plan for the reinspection
and closeout of these
items.
