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.

說(shuō)明書

In yet another embodiment, a cooling jacket (not shown) can be provided on the exterior surface of the containment vessel 2218, which serves to remove heat from the circulating reflective material on the interior surface of the containment vessel 2218. This may be done in addition to or instead of an exterior reflective material cooling circuit.

As described above, the overall reflectivity of the reflector configuration of FIG. 22 may be controlled by controlling the flow rate of reflective material through the reflectors as well as by inserting or removing rods or other components containing moderating materials or materials of different reflectivity from that of the circulating reflective material.
