To enhance the performance of the TDMC neutron transport analysis, a new version of McCARD utilizing GPUs, named McCARD/G, is under development. This version introduces an MC neutron tracking module that employs an event-based algorithm and features a generalized lattice geometry treatment module. Additionally, significant adaptations of other major modules have been made to optimize for the GPU architecture. The capabilities of McCARD/G have been verified through the C5G7-TD benchmark, which shows good agreements with the reference results. Furthermore, McCARD/G’s efficacy is also demonstrated via an experimental benchmark conducted at the Kyoto University Critical Assembly.
