Attention:
Mr. G. C. Sorensen,
Manager
Regulatory
Programs
Gentlemen:
Subject:
NRC Emergency Operating
Procedures
Team
Inspection at Washington Nuclear Project
No.
2
(WNP-2)
This refers to a special,
announced
team inspection of your emergency operating
procedures,
conducted
by the
NRC, at the
WNP-2 site from September
4 - 13, 1990.
The findings and details of this report were discussed
during the inspection,
and summarized
during the exit meeting with members of your staff identified
in the enclosed
inspection report.
Areas evaluated
during the inspection included the review of your Emergency
Operating
Procedures
(EOPs),
EOP support
procedures
(ESPs),
some supporting
procedures
involved in the use of EOPs,
the documents
used to develop the
EOPs, the
EOP verification and validation program,
and the
EOP training and
evaluation
program.
The inspection included plant walkdowns of the
and
EOP support procedures
with operators,
evaluation of a crew's performance
in
the simulator,
and
a human factors evaluation.
The team determined that the
WNP-2 EOPs,
when used
by trained operators,
appeared
adequate
to mitigate emergency situations.
However, they were, in
some instances, difficult for operators
to use, with the potential for causing
safety significant errors.
The team identified three deviations
from the Boiling Water
Reactor
Owners'roup
{BWROG), Emergency
Procedure
Guidelines
{EPGs), Revision 4, that are of
specific concern.
The acceptability of your justifications for these
deviations could not be determined
by the inspectors.
These three
items
have
been referred to the Division of Reactor Projects, Office of Nuclear Reactor
Regulation
(NRR), for further evaluation.
Furthermore,
the team considered
that the development of the
EOP writer'
guide,
and the implementation of the verification and validation program for
the
EOPs,
were marginal.
This resulted
in procedures
that, in places,
were
difficult for operators
to use, with a potential for causing safety-significant
errors.
The team also noted that
human factors considerations
in this program
were lacking, particularly, in its validation aspects.
Two detailed findings were of particular
concern.
First,
one deficiency
involved the lack of EOP guidance for determining the temperature
near
9011080210
90102'DocK05ooos97
G
PNU
AT)> Nx
Reactor Pressure
Vessel
(RPV) level instrument
runs in the secondary
containment.
This information is essential if operators
are to correctly
apply
EOP 5.0.0,
Caution I, "RPV Saturation
Temperature."
Second,
our
inspectors
found that your staff had
made errors in transcribing
some of the
approved engineering
derived curves to
EOP 5.0. 1,
"EOP Graphs," Revision 0.
Some of these errors
would have allowed operations
in the area defined
by
engineering
as unsafe.
Your letter responding to this finding should address
the potential
generic applicability of this issue to other curves
used in the
EOPs.
These findings were discussed
with the members of your staff identified in the
attached report.
You are requested
to respond to these findings, documenting your proposed
corrective actions,
including the schedule for the completion of these
corrective actions, within 30 days.
In accordance
with 10 CFR 2.790(a),
a 'copy of this letter and the enclosures
will be placed in the
NRC Public Document
Room.
The response
directed
by this letter is not subject to the clearance
procedures
of the Office of Management
and Budget
as required
by the Paperwork Reduction
Act of 1980,
PL 96-511.
Should you have
any questions
concerning this inspection,
we will be pleased
to
discuss
them with you.
Sincerely,
E2 ~g,
Roy P.
