THERMIONIC CONVERTER REACTOR Russian patent published in 2001 - IPC

FIELD: nuclear power engineering; spacecraft nuclear power units. SUBSTANCE: converter reactor has power-generating stacks. Each stack is, essentially, pressurized vessel accommodating power- generating fuel assemblies and two coolant headers placed on two ends of power-generating stacks. Each stack incorporates internal partition that functions to hydraulically separate fuel assemblies of stack and one of headers to form two groups. Coolant inlet and outlet pipes are connected to respective parts of partition-separated header. Partition may be made of heat-insulating material. EFFECT: simplified design, reduced size and mass of radiation shield. 2 cl, 3 dwg
