ACT HEAT-PIPE COOLED REACTOR Russian patent published in 2016 - IPC G21C1/20 G21C15/28 

FIELD: nuclear engineering.

SUBSTANCE: invention relates to nuclear engineering, namely, to design of ACT heat-pipe cooled reactors. Reactor core consists of cells, containing channel with nuclear fuel and coolant in their symmetry center, surrounded by neutrons moderator. Neutrons moderator consists of 2 layers, wherein adjacent to channel layer has atomic weight , and outer layer has light atomic weight. In nuclear reactor fuel contains mixture of fertile nuclides, for example, ²³⁸U and ²³²Th, as coolant lithium allot is selected enriched with ⁷Li isotope, with heavy atomic weight nuclides, for example, Bi, and in inter channel space is lead with prevailing content of ²⁰⁸Pb isotope.

EFFECT: higher reactor safety in case of coolant overheating owing to reduced deceleration "step" - energy losses by neutrons at deceleration in neutrons reactor energy entire range and in increase of their resonant absorption in fuel owing to deceleration on inter-channel decelerator nuclei with heavy atomic weight .
