This study presents benchmark activities conducted by a research committee of the Atomic Energy Society of Japan to enhance the reliability of nuclear fuel cycle simulators. Standard reactor libraries and phased benchmark scenarios were developed and applied to stepwise validation exercises. The results clarify consistency of simulators on burnup calculation and impact of human error. The results for 11 large-scale scenarios are also provided for future activity.

Nuclear fuel cycle simulators (NFCSs) are widely used but suffer from uncertainties and a lack of benchmarking for large, complex scenarios. To address this, the Atomic Energy Society of Japan established a committee to develop standard reactor libraries and benchmarking scenarios. Multiple Japanese NFCSs will analyze these scenarios, and the results will be published to improve NFCS reliability.
