Abstract

Abstract

In order to analyze and evaluate the Th-U cycle scheme of starting reactor with low enriched uranium (LEU), Pu and transuranium (TRU) in fast neutron chloride salt reactor, the concepts of regeneration ratio and replacement ratio are defined to compare the conversion information of key nuclides in the Th-U cycle reaction chain. The burnup analysis of pre-breeding scheme under three different start-up fuels is carried out by using TMCBurnup program. The analysis results show that the under the pre-breeding cycle scheme, the production of ²³³U can be quickly completed by using three fuels for start-up, in which the TRU start-up transition mode has a larger replacement ratio, the LEU start-up transition mode has a larger ²³³U regeneration ratio, and the core always has a large negative temperature feedback coefficient in the whole operation cycle.
