==
BACKGROUND
==
In
==
an
==
application
==
dated
==
August
==
27,
==
1999,
==
GA
==
requested
==
that
==
their
==
license
==
be
==
amended
==
to
==
remove
==
authorized
==
activities
==
at
==
Building
==
31-1
==
from
==
the
==
license
==
and
==
to
==
release
==
Building
==
31-1
==
for
==
unrestricted
==
use.
==
This
==
facility
==
is
==
the
==
Neutron
==
Radiography
==
Building
==
on
==
GA's
==
main
==
site.
==
GA
==
conducted
==
a
==
survey
==
of
==
Building
==
31-1
==
in
==
accordance
==
with
==
the
==
NRC-approved
==
General
==
Atomics'
==
Site
==
Decommissioning
==
Plan
==
and
==
provided
==
the
==
results
==
of
==
that
==
survey
==
with
==
their
==
submittal.
==
The
==
licensee
==
used
==
the
==
same
==
methodology
==
as
==
they
==
used
==
for
==
decontamination
==
and
==
decommissioning
==
of
==
the
==
other
==
facilities
==
previously
==
released
==
at
==
the
==
site.
==
DISCUSSION
==
Building
==
31-1
==
consists
==
of
==
five
==
rooms.
==
These
==
rooms
==
were
==
used
==
as
==
laboratories,
==
offices,
==
==
and
==
source
==
material
==
storage
==
vaults,
==
and
==
a
==
control
==
room
==
for
==
a
==
critical
==
assembly
==
that
==
had
==
been
==
previously
==
located
==
in
==
nearby
==
Building
==
31-2.
==
GA
==
completed
==
the
==
decontamination
==
and
==
final
==
survey
==
of
==
Building
==
31-1
==
and
==
submitted
==
a
==
final
==
report
==
entitled,
==
"Final
==
Radiological
==
Survey
==
Performed
==
at
==
General
==
Atomics'
==
Building
==
31-1,"
==
dated
==
August
==
25,
==
1999.
==
The
==
report
==
documents
==
the
==
results
==
of
==
radiological
==
measurements
==
completed
==
inside
==
the
==
building
==
and
==
on
==
the
==
roof,
==
and
==
of
==
soil
==
samples
==
collected
==
from
==
beneath
==
the
==
concrete
==
floor
==
inside
==
the
==
building
==
and
==
from
==
the
==
footprint
==
areas
==
1
==
meter
==
outside
==
the
==
building.
==
The
==
decontamination
==
procedures
==
and
==
survey
==
methodology
==
were
==
the
==
same
==
rigorous
==
procedures
==
as
==
used
==
in
==
the
==
Group
==
6,
==
Group
==

==

==
Group

Facility,
==
and
==
others

which

have
==
been

previously

released.
==
GA's
==
radiological
==
measurements
==
and

soil

sample
==
results
==
provided
==
in
==
the
==
final
==
survey
==
report
==
for
==
Building

31-1
==
demonstrate
==
that
==
the
==
building
==
and
==
soil
==
underneath
==
the
==
building
==
and
==
in
==
the
==
surrounding
==
footprint
==
meet
==
the
==
NRC-approved
==
criteria
==
for
==
release
==
to
==
unrestricted
==
use
==
indicated
==
in
==
the
==
GA
==
Site

Plan.
==
Inspectors
==
from
==
Region
==
IVperformed
==
a
==
confirmatory
==
survey
==
of
==
Building
==
31-1
==
on
==
August
==
2-6,
==
1999,
==
and
==
collected
==
numerous
==
split
==
samples
==
for
==
independent
==
analysis
==
(Inspection
==
Report
==
70-734/99-01)
==
and
==
determined
==
the
==
following:
==
Building
==
31-1
==
housed
==
offices,
==
laboratories,
==
storage
==
vaults
==
and
==
a
==
control
==
room
==
for
==
a
==
critical
==
facility
==
that
==
was
==
located
==
in
==
another
==
building.
==
The
==
areas
==
were
==
classified
==
as
==
either
==
"non-suspect
==
affected"
==
or
==
"suspect
==
affected
==
areas."
==
The
==
licensee
==
made
==
surface
==
and
==
area
==
measurements
==
and
==
analyses
==
of
==
the
==
walls,
==
floors,
==
roof,
==
and
==
roof
==
tar
==
and
==
gravel
==
layers.
==
Confirmatory
==
surveys
==
were
==
accomplished
==
in
==
these
==
areas
==
by
==
the
==
NRC
==
during
==
this
==
inspection.

The

"Final

Building

==
dated

August

==
was
==
reviewed
==
and

found

acceptable.
==
The

licensee
==
has
==
implemented
==
a
==
program
==
for
==
the
==
conduct
==
and
==
documentation
==
of

final

surveys
==
that

follows

the

contained

in

"Manual

for

Conducting
==
Radiological
==
Surveys

in

==
Based
==
upon
==
GA's
==
final
==
survey
==
data
==
and
==
NRC
==
confirmatory
==
surveys
==
and
==
soil
==
samples,
==
NRC
==
has
==
determined
==
that
==
Building
==
31-1
==
decommissioning
==
meets
==
the
==
NRC-approved
==
release
==
criteria
==
and
==
that
==
Building
==
31-1
==
can
==
be

released

for

unrestricted

ENVIRONMENTAL
==
REVIEW
==
Based
==
on
==
the
==
information
==
submitted
==
by
==
GA
==
and
==
confirmed
==
by
==
NRC
==
inspection,
==
the
==
staff
==
has
==
determined
==
that
==
the
==
changes
==
to
==
the
==
license
==
are
==
related
==
to
==
decreased
==
operations
==
at
==
the
==
facility
==
resulting
==
from
==
the
==
proposed
==
overall
==
decommissioning
==
of
==
the
==
site.
==
Accordingly,
==
the
==
staff
==
has
==
determined
==
that
==
the
==
criteria
==
in
==
10
==
CFR
==
51.22(c)(1
==
1)
==
for
==
categorically
==
excluding
==
an
==
action
==
from
==
an
==
environmental
==
review
==
have
==
been
==
met.
==
Therefore,
==
neither
==
an
==
Environmental
==
Assessment
==
nor
==
Environmental
==
Impact
==
Statement
==
is
==
necessary
==
for
==
this
==
action.
==
CONCLUSION
==
The
==
staff
==
concludes
==
that
==
GA's
==
request
==
to
==
reduce
==
licensed
==
activities
==
meets
==
regulatory
==
requirements
==
and
==
that
==
there
==
is
==
reasonable
==
assurance
==
that
==
the
==
proposed
==
action
==
will
==
not
==
adversely
==
impact
==
upon
==
the
==
health
==
and
==
safety
==
of
==
the
==
public
==
or
==
the
==
environment.
==
The
==
Region
==
IVPrincipal
==
Inspector
==
has
==
no
==
objection
==
to
==
this
==
proposed
==
action.
