Description

In the probabilistic safety assessment (PSA), the fault tree/event tree technique has been widely used to evaluate accident sequence frequencies. However, event transition which operators actually face can not be dynamically treated by the conventional technique. Therefore, we have made the dynamic analysis program(DYANA) for event transition for a liquid metal cooled fast breeder reactor. In the previous development, we made basic model for analysis. However, we have a problem that calculation time is too long. At the current term, we made parallelization of DYANA using MPI. So we got good performance on WS claster. It performance is close to ideal one. (author)
