The Profitability of Nuclear Power Plant Waste Products. May 14 2010 Depleted uranium is a waste obtained from producing fuel for nuclear
reactors and atomic bombs. The material used in civil and nuclear military
industry is uranium U-235, the isotope which can be fissioned. Since this
isotope is found in very low proportions in nature, the uranium ore has to
be enriched, i.e., its proportion of the U-235 isotope has to be
industrially increased. This pocess produces a large amount of radioactive
depleted uranium waste, thus named because it is mainly formed by the other
non-fissionable uranium isotope, U-238 and a minimum proportion of U-235.
American military industry has been using depleted uranium to coat
conventional weaponry (artillery, tanks and aircraft) since 1977, to
protect its own tanks, as a counterweight in aircraft and Tomahawk missiles
and as a component for navigation instruments. This is due to depleted
uranium having characteristics making it highly attractive for military
technology: firstly, it is extremely dense and heavy (1 cm3 weighs almost
19 grammes), such that projectiles with a depleted uranium head can
penetrate the armoured steel of military vehicles and buildings; secondly,
it is a spontaneous pyrophoric material, i.e., it inflames when reaching
its target generating such heat that it explodes.
