JAEA has been engaged in the development of JAMPAN, a platform for multi-physics simulations, to enable the numerical simualtons for enhancing the quality and safety of the light water reactor design. In this study, ACE-3D, which is based on a three-dimensional two-fluid model capable of general-purpose multidimensional thermal-hydraulic calculations, was selected as the thermal-hydraulic calculation code. Furthermore, a JAMPAN module was developed to facilitate a coupled MVP/ACE-3D neutronics/thermal-hydraulics simulation. In the presentation, the results of the simulation for an 8×8 BWR fuel assembly with JAMPAN will be presented.
