Question
for
Discussion:
A
question
was
raised
by
Southwest
Research
Institute
(SwRI)
regarding
fiber
mass
units,
which
were
labeled
as
pounds
mass
(lbm),
at
the
STP
meeting
of
02/04/15.
The
table
in
question
(RoverD
table)
cited
weld
locations
capable
of
introducing
more
fine
fiber
mass
to
the
containment
pool
than
was
tested
during
a
July
2008
STP
flume
test.
STP's
understanding
is
that
SwRI
stated
they
obtained
similar
numeric
values
but
only
when
units
of
kilograms
are
applied.
Confirmatory
Comparison:
It
is
not
clear
what
steps
SwRI
followed
to
generate
or
extract
comparative
information
from
CASA
Grande
v1.6.
The
numeric
results
STP
presented
require
non-standard
output
methods
that
must
be
obtained
from
the
vendor
(Alion).
Also,
independent
verification
of
results
obtained
should
be
done
to
ensure
correct
values
are
being
obtained.
In
the
following,
process
steps
and
verification
are
summarized.
Extensive
QA
comparisons
have
been
performed
between
manually
directed
CAD
calculations
of
total
debris
volume
and
automated
CASA
Grande
calculations
of
total
debris
volume
within
a
ZOI.
A
comparison
of
a
spherical
DEGB
ZOI
at
weld
point
31-RC-1402-NSS-RSG-1D-ON-SE
located
on
the
Loop
D
Crossover
Leg
(31-in.)
shows
good
agreement
between
manual
CAD
extraction
and
the
automated
CASA
calculation
(Table
1
below).
Further
partitioning
of
total
fiber
into
size
fractions
by
fractional
composition
shows
identical
agreement
between
manual
and
automated
evaluation
when
starting
with
the
same
total
volume.

Most
microtherm
exists
within
pipe
penetrations
of
the
secondary
shield
wall
that
are
difficult
to
isolate
manually.
Recommended
Procedure:
The
mass
of
fine
fiber
introduced
to
the
containment
pool
from
each
break
scenario
is
not
a
standard
output
of
CASA
Grande
v1.6,
which
was
provided
for
review
to
SwRI.
Alion
recommends
that
a
knowledgeable
user
follow
the
steps
below
to
extract
fine-fiber
quantity
from
CASA
in
units
of
pounds
mass.
