THE GLOBAL CRISIS

The concentration of the fissile isotope uranium-235 in natural uranium is only around 0.71%. To make nuclear fuel for most reactors this has to be increased to around 3–5% through the operation of uranium enrichment plants. A significant waste product of enrichment opera - tions is depleted uranium, with current estimates of 1.7

Nuclear Fission Fragments

A common pair of fragments from uranium-235 fission is xenon and strontium:. Highly radioactive, the xenon decays with a half-life of 14 seconds and finally produces the stable isotope cerium-140. Strontium-94 decays with a half-life of 75 seconds, finally producing the stable isotope zirconium-94. These fragments are not so dangerous as intermediate half-life …
