HORIZONTAL REACTOR WITH DISPLACING NEUTRON REFLECTOR AND METHOD OF ITS OPERATION Russian patent published in 2014 - IPC G21C1/00 

FIELD: power engineering.

SUBSTANCE: proposed nuclear power reactors allow compensation for reactivity lost in fuel burnup at one section of core region by displacement of reflector to core region section with "fresh" fuel. Reactor core region is arranged in horizontal body of the reactor, over its entire length. Displacing neutron reflector surrounds reactor body from above and on sides, outside the reactor body, to surround core region section inside the reactor body whereat controlled chain reaction of fission and energy release occurs. Stationary bottom reflector is arranged under reactor body. Heat carrier is forced in reactor body along core region. At decrease in reactivity margin in energy release area displacing reflector sifts to adjacent core region section with "fresh" fuel to involve said fresh fuel in energy release process.

EFFECT: fuel element perennial life-time with no reloading, common energy release, decreased reactor body weight, ruled out maintenance and storage of fresh and used fuel.
