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.

In an implementation, neutron reflector materials 1804, 1806 may circulate in channels 1808, 1810 with input and output ports above fuel region 1802 such that no fixtures or ports are needed beneath the reactor. In other implementations, neutron reflector materials 1804, 1806 may flow in only one direction, either in an upward or downward direction, through channels 1808, 1810 with one port above fuel region 1802 and another port below fuel region 1802. In yet other implementations, neutron reflector materials 1804, 1806 may comprise a semi-stagnant or creeping flow through channels 1808, 1810. In yet other implementations, neutron reflector materials 1804, 1806 may flow through radial input and output ports.
