Abstract: By using computer code WIMS/CENDL, the effects of some parameters, core configuration such as fuel element structure, neutron flux and burn-up, are discussed in this paper. It is shown that high neutron flux, small fuel rod diameter, large volume ratio of coolant to fuel, seed-blank heterogeneous core arrangement and 231Pa chemical separation are necessary for reducing 228Th production in reactor.

Key words: 228Th, Th-U fuel cycle, Thermal reactor
