What about the waste products from a hybrid fusion-fission reactor using natural U fuel? Would the neutron source drive the fission products to be either stable elements or to radioisotopes with shorter half life?
What about using LENR as the neutron source? Some LENR fuels are reputed to cause "undesirable" neutron emission. Suppose that were harnessed.
