separated by solvent extraction (chemical
separation).

Due to the remaining radioactive properties, the
nuclear fuel cycle byproducts must be controlled
and/or disposed. These byproducts can be divided
into two categories--low-level waste (LLW) and
high-level waste (HLW).
LLW
a.
The RCM glossary defines low-level waste
(LLW) as "Waste that contains
radioactivity and is not classified as high-
level waste, transuranic waste, spent
nuclear fuel, or byproduct material as
defined in Section 11e(2) of the Atomic
Energy Act, as amended. Test specimens
of fissionable material irradiated only for
research and development and not for
production of power or plutonium may be
