Special Nuclear Material
The spectra of
232
Th and

U are very similar.
160 ka
Special Nuclear Material
Used in nuclear power generators. Although the United States demon-
strated/detonated in 1955 a
233
U based bomb core, the use of
233
U
within a weapon is not as viable of a choice for a weapon when com-
pared to
235
U.
704 Ma;

Special Nuclear Material
A mixture of
238
U and
235
U in various concentrations from depleted
uranium (DU) to highly enriched uranium (HEU). Can be effectively
used to manufacture a nuclear ission weapon, and is a primary con-
cern because the design complexity required is far less than that
required for a
239
Pu based weapon.
When the “U, Pu” setting (see "6.4 Identification Settings" on page 1) is
set to ”Separate”, the concentrations of
235
U and
238
U will determine
which of the following is displayed:
