Enriched
uranium
with
0.9-2%
uranium-235,
requiring
a
special
moderator
with
very
low
neutron
absorption
(such
as
heavy
water
or
high-purity
graphite)
in
order
to
be
able
to
sustain
a
nuclear
fission
chain
reaction.
Used
to
increase
power
output
and
efficiency
in
a
few
types
of
nuclear
reactors
capable
of
running
on
natural

downblending
of
highly-enriched
uranium
from
decommissioned
nuclear
weapons
into

uranium
suitable
