fast reactor
Noun
(nuclear
physics,
engineering)
A
nuclear
reactor
with
no
moderator,
using
fast
neutrons
directly
in
a
controlled
fission
chain
reaction
without
slowing
them
down;
this
allows
for
a
much
more
compact
reactor,
and
causes
the
reactor
to
use
fissile
material
much
more
efficiently,
and
to
generate
larger
quantities
of
high-energy
neutrons
which
can
be
used
for
breeding
more
fissile
material
or
producing
other
useful
radioactive
nuclides,
but
requires
the
use
of
highly-enriched
uranium
(at
least
20%
uranium-235)
or
other
fuel
containing
a
similarly
high
concentration
of
fissile
material.
Japanese Meaning
高速炉（高速中性子炉）：減速材を用いず、速い中性子で制御された核分裂連鎖反応を実現する原子炉。これにより、よりコンパクトな炉心設計や燃料の効率的利用、さらには核分裂性物質の増殖や他の有用な放射性核種の生成が可能となる。ただし、高濃縮ウラン（ウラン‐235が20%以上）等の高濃度の核分裂性物質が必要となる。
