IN SPECTION
(REPORT NO.'0-
397/91-27)
This letter refers to the inspection
conducted
by L. Hiller, C.
VanDenburgh,
H. Biamonte,
G, Galleti,
and T. Headows
on July 30-August 2,, 1991
and to the
followup review 'conducted
by T. Walker,
R.
Frahm Sr.,
A. Cubbage,
a'nd J.
Henniger
on August 12-27,
1991 of activities authorized
by
NRC License
No.
NPF-21, at the Washington
Nuclear Project,
Unit 2.
The initial inspection
reviewed revised
emergency
operating
procedures
(EOPs),
operator training,
and Revision
6 of your corrective action plan.
The
followup review was
a more detailed
review of the technical
basis of WNP-2
emergency
operating
procedures,
The inspection
concluded that you had not adequately justified numerous
deviations
from the Boiling Water Reactor Owner's
Group
(BWROG) Emergency
Procedure
Guidelines
(EPGs).
The inspection identified several significant
deviations
which lacked
a sound,
documented,
and technically complete
justification.
Some
EOPs directed actions which were considered
less
safe
than the
EPG recommendations,
The inspection
also identified numerous
inconsistencies
and incomplete justifications.
These
are detailed
in the
report,
These findings lead
us to conclude that your
EOP verification and validation
program was flawed in its execution
and quality.
The inspection also noted that the
EOP flow chart structure
had recently
been
significantly improved
by your Phase
I
EOP improvement'progran!,
However,
the
inspection
concluded that the
new
EOP flow charts
were still confusing
and
difficult to use in some cases.
This finding was in addition to the broader
program weaknesses
identified above.
The inspection also concluded that the operator training process
was
satisfactory for restart of WNP-2.
Finally, the inspection
concluded that
the corrective action plan was being used effectively tn track detailed
commitments.

At the meeting at
NRC Headquarters
on August 28,'991,
the Supply System
proposed
to further modify the
EOPs (the
Phase II program) to remove
some of
the deviations
between
the
and the
and to submit
an acceptable
rationale for the remainder.
You committed to subn>it this proposal
in response
to this inspection report,
Please
provide that response,
including your
schedule for corrective actions, within thirty days
of. receipt of this report,
Your. response
should
address
the
improvement in methods
you will use to ensure
that
an effective verification,and validation of the revised
EOPs occurs
as
well as
each of the inspection report's findings.
Please
indicate in your
response
where certain
have
been modified further to eliminate
some of
the deviations
which existed at the time of the inspection or review.
In accordance
with 10
CFR 2.790(a),

and your
response will be placed in the
