Washington Public Power Supply System

Attention:
Mr. G.
C. Sorensen,
Manager
Regulatory Programs
Gentlemen:
Sub)ect:
NRC Inspection Finding Related to NUREG 0737, Item II.F.l,
Attachment 2, Inspection Report No. 50-397/85-20,
Unresolved
Item 85-20-04
As a part of Region V's post implementation review of the adequacy of your
reactor building POST LOCA sampling system,
a question
was raised
concerning
the affect sample line plate out might have
on your ability to quantify the
amount of iodine released
following an accident.
In response
to this question,
you submitted "Nuclear Plant No.
2 Position
on
Iodine Plate-out" in a letter to Mr. J.
B. Martin, Regional Administrator,
dated
June
27,
1985 (G02-85-347).
In your position you contend that requiring you to evaluate
the iodine plate
out in your effluent sample lines (required by Item II.F.1.2 of NUREG-0737)
is not appropriate
since,
due to the large exposed metal areas
in'BWRs, ail
"plateable" iodine species will have been
removed before they reach the
sampling location.
You base this position on the design basis analysis in
the
FSAR.
We have reviewed your rational and do not concur with your position. It is
our position that each
BWR licensee
(including WNP-2) must
show that their
system. provides
a representative
sample
as required by NUREG 0737,
Item II.F.1.2.
Our position is based
on the following considerations:
It is inappropriate
to use design basis analysis
as reasoning for not
complying with a NUREG-0737 item.
The requirements
in NUREG-0737 are
intended
to mitigate the consequences
of an accident which may or may
not have been specifically considered in the design basis analysis.
Therefore,
the NUREG-0737 requirements
are in addition to those
"
requirements
mandated
by design basis analysis.
