Title: HEAT PIPE MOLTEN SALT FAST REACTOR WITH STAGNANT LIQUID CORE
Abstract:
A molten salt reactor (10) is described that includes a containment vessel (12), a reactor core (14) housed within the containment vessel, a neutron reflector (18) spaced from the containment vessel and positioned between the core and the containment vessel, a liquid fuel (34) comprised of a nuclear fission material dissolved in a molten salt enclosed within the core, a plurality of heat transfer pipes (32), each pipe having a first end (92) and a second end (94), wherein the first end is positioned within the reactor core for absorbing heat from the fuel, a heat exchanger (70) external to the containment vessel for receiving the second end of each heat transfer pipe for transferring heat from the core to the heat exchanger, and at least one and preferably two or more reactor shut down systems, where at least one may be a passive system and at least one or both may be an active or a manually operated system. The liquid fuel in the core is kept within the core and heat pipes are used to carry only the heat from the liquid core to the heat exchanger.
