Transuranic elements (Np, Pu, Am, Cm, ...) and fission products are produced by the operation of nuclear reactors, e.g. light water reactors (LWR). Because of their radio-toxicity, these elements have to be safely separated from the biosphere and stored until their final decay.
By the process of transmutation into stable or fissionable elements a significant reduction of the amout and the radio-toxicity of Transuranic Elements (Plutonium (Pu) and Minor Actinides (MA)) and long lived fission products (LLFP) should be achieved. The storage time will be dramatically reduced by transmutation.

With transmutation/incineration of Pu + MAs + LLFPs the radiotoxicity curve should approach the curve for fission products. This will reduce time-scales from geologic scale to historic scale. This should relieve concerns of surveillance, leakage to biosphere, problems of documentation, proliferation risk etc.
