Before revision: Desired nuclear transmutation could be employed deliberately (rather than as an unavoidable consequence of nuclear fission and neutron irradiation) either to transmutate high level waste (such as long-lived fission products or minor actinides) into less harmful substances, for producing radionuclides for use in nuclear medicine or to produce precious metals from low-priced feedstocks.
