Abstract

Elimination of long-lived transplutonium actinides by fissioning in a generic actinide burner reactor (a reactor fueled solely with waste actinides) was investigated. The results showed that actinide elimination by fissioning is enhanced by increasing the average energy of the neutron flux spectrum. In addition, the reactivity worths and the fission-to-capture rate ratios of the individual actinide nuclides increased with increasing flux spectrum energy. The fuel value of waste actinides was studied, and the replacement of at least some conventional mixed-oxide fast reactor fuel by waste actinides (to conserve a fuel resource) was proposed. It is calculated that the time required to reach equilibrium actinide concentrations in the reactor core, after many refueling periods, is shorter for reactors having higher neutron flux energies. Also, increasing the specific power density within the reactor core both decreases the equilibrium actinide concentrations in the core and increases the time required for equilibrium conditions.
