摘要
Configurations of molten fuel salt reactors are described that utilize neutron-reflecting coolants or a combination of primary salt coolants and secondary neutron-reflecting coolants. Further configurations are described that circulate liquid neutron-reflecting material around a reactor core to control the neutronics of the reactor. Furthermore, configurations which use the circulating neutron-reflecting material to actively cool the containment vessel are also described. A further configuration is described that utilizes a core barrel between a reactor core volume of molten fuel salt and a reflector volume, in which the reflector volume contains a plurality of individual reflector elements separated by an interstitial space filled with molten fuel salt.

The reflection assembly may further be in thermal communication with one or more heat exchangers, and therefore function as a secondary coolant for the reactor core. In one implementation, heat exchangers are thermally coupled to channels for conducting the flowing reflector material. Another implementation may utilize a tube-and-shell heat exchanger wherein a first channel conducts a flowing reflector material in a first direction, and one or more additional channels conduct the flowing reflector material in a second direction through one or more tubes surrounded by flowing molten fuel salt.
