Critical mass
A
critical mass
is the smallest amount of
fissile
material needed for a sustained
nuclear chain reaction
. The critical mass of a fissionable material depends upon its
nuclear
properties (specifically, the
nuclear fission
cross-section
), its
density
, its
shape
, its
enrichment
, its purity, its
temperature
, and its surroundings. The concept is important in
nuclear weapon design
.
