Abstract

This study evaluates the physical properties of the molten salt Flinabe, using molecular dynamics simula-tions to discuss its applicability to a fusion blanket sys-tem. More specifically, the simulations calculate the den-sity and viscosity of Flinabe to facilitate further discus-sion of the applicability from the viewpoint of the heat removal of the first wall. The results of the simulations are compared with data reported in earlier publications, which support the validity of the simulations. This study reveals that Flinabe tends to have lower viscosity than Flibe even when they contain almost the same BeF2. Ana-lyzing the results of the simulations confirms that the de-gree of polymerization in Flinabe correlates with its vis-cosity, as that in Flibe does. The analyses also revealed, however, that the correlation in the case of Flibe is not directly applicable to the case of Flinabe.
