irreversibilitet /
irreversibily
- If the nuclear weapons are fission bombs, making use of highly
ennriched uranium, disarmament of these weapons could be made
completely irreversible by mixing the highly enriched uranium with
ordinary uranium. The result would be uranium in which the common
isotope predominated over the rare fissle isotope, and thus the
resulting uranium could not be used in bombs. Getting rid of
plutonium irreversibily is more difficult, but it has been proposed
that plutonium could be deposited in the bottom of deep mine
shafts, and access to it could be made almost impossible by
exploding charges conventional explosives in such a way that the
mine shafts would collapse and be blocked by thousands of tons of
rocks. Most thermonuclear bombs make use of rare isotopes of
hydrogen and lithium, and these could be destroyed irreversibly by
mixing the rare isotopes with the common isotopes of hydrogen and
lithium.
