In this study, the error analysis for transmutation systems was performed. As the transmutation system, Fast Reactor (FR) and Accelerator Driven System (ADS) were employed and the errors caused by the nuclear data for these systems were estimated by using the covariance data prepared in JENDL-3.3. The effect of MA-loaded critical experiments was also investigated by using the cross section adjustment procedure. It was considered that the MA-loaded critical experiment would be performed at Transmutation Physics Experimental Facility (TEF-P) which has been planned its construction in the second phase of J-PARC project. The analysis results presented quantitatively that the errors caused by the nuclear data for these systems were improved by the MA-loaded experiments. The MA-loaded experiment is one of the most useful methods to improve the error caused by the nuclear data which relates to the reliability and the economic efficiency of the transmutation systems.
