Many elements and nuclides which are different from those used in conventional nuclear reactors will be employed in transmutation of TRU by chloride molten salt fast reactors (CMSFRs). Compared to the nuclides which are already used in conventional reactor concepts, nuclear data of those "exotic" nuclides to be used in CMSFR are not verified sufficiently. Therefore, validation of these nuclear data is necessary. In this study, we analyzed uncertainty of transmutation properties of TRU in CMSFR caused by the uncertainties of nuclear data of ³⁵Cl.
