This is, of course, one of the main research applications envisaged for MYRRHA. Transmutation, in brief, is the transformation of one isotope into another one by bombarding the atom with a high neutron flux. The underlying idea is to transmute long-lived fission products and minor actinides, the most annoying due to their long half-life nuclear waste, into less long-lived waste, reducing the burden on the nuclear waste stocks.
MYRRHA is not intented as an industrial transmutator, but as a first research tool for the effectiveness of the process. It will learn us a lot about the procedures to be used during transmutation exercises and will provide a lot of information to the next generation, industrial transmutators.
