Safety-related neutronics parameters of a molten salt actinide recycler and transmuter

This paper describes studies on reactivity coefficients and kinetics parameters in a fertile-free molten salt reactor. This reactor concept originated at RRC-KI for burning and transmutation of LWR spent fuel. The studies are performed at several institutions in the framework of a Coordinated Research Project initiated by the IAEA. The participants investigated the influence of different codes, computation techniques and nuclear data libraries on the neutronics parameters. It is shown that the reactivity coefficients are favorable for reactor safety. (authors)
