Loading Scheme Research on the First Criticality of China Experimental Fast Reactor

The theoretical calculation results were studied for the first fuel loading of China Experimental Fast Reactor (CEFR). By comparison of theoretical calculation and test results, the loading scheme was evaluated, and the calculation code was validated. The results indicate that the scheme for the first fuel loading of CEFR satisfies test requirement. The theoretical calculation and test results show the good agreement, which means that the calculation code can be utilized to research of fuel loading scheme.
