Towards realizations of the demonstration reactor in around 2025 and the commercialized reactor in around 2050, a investigation on the conceptual core design of the sodium-cooled fast reactor (JSFR: Japan Sodium-cooled Fast Reactor) is under going. This paper presents the elavuation of the core design prediction accuracy based on the studies related to the latest nuclear data.

JENDL-4.0 is planned to be applied to the core neutronics design for next generation FBRs. In order to improve the accuracy and reliability of the neutronics core design, reflection of the accumulated integral data is essential, which are obtained in critical facility experiments and power reactor tests. Additionally, the specific method of reflection should be prudently selected based on the comparison in advantages and disadvantages from the various points of view. The present study shows the general consistency between the calculation data of experiments/tests and the covariance data of cross-sections by comparing the prediction accuracies of neutronics core design using the combinations of several core design methods and uncertainty evaluation methods based on the constant set with JENDL-4.0.
