To incinerate trans uranium elements (TRU) effectively, incineration characteristics of an integral molten chloride salt fast reactor (IMCSFR) was studied. The fuel salt used is a mixed salt of NaCl, CaCl₂ and TRUCl₃. This fuel salt is expected to have solidification temperature of about 530^oC and TRU solubility of about 30mol%. The IMCSFR can incinerate 64% of fed TRU in 40 years operation. Furthermore, when proper IMCSFRs are combined and TRU are incinerated in three stages of 40 years each in sequence, 93% of the fed TRU can be incinerated and converted into energy in 120 years. These incineration characteristics of IMCSFR were analyzed by SRAC with SRACLIB-JDL40.
