The benchmark problem for JAEA-ADS was proposed in IAEA CRP (Coordinated Research Program) on ADS (Accelerator-Driven System). The purpose of this benchmark problem is to obtain fundamental knowledge of calculation accuracy for the neutronics design of a commercial grade ADS at the present time. In this benchmark problem, the calculations of a criticality and a burnup behaviour for JAEA-ADS were proposed and three institutes aimed the problem. The sensitivity and uncertainty analyses were also performed to know the current situation of covariance data prepared in nuclear data libraries. Through the benchmark calculations, it was confirmed that the prediction accuracy of the criticality and the transmutation amount for the ADS had the problem.
