FIELD: physics, atomic power.
SUBSTANCE: invention relates to nuclear reactor fuel elements. A fuel element contains metal fuel in form of particles of at least one enriched alloy, wherein the particles are compacted into a fuel column. The fuel element containing particulate metal fuel can also have cladding and/or gas plenum. The nuclear reactor having a fuel column of compacted particulate metal fuel uses an inert gas as a coolant and liquid sodium.
EFFECT: enabling use of spent nuclear fuel of light-water reactors in fast reactors and enabling switch to a closed fuel cycle.
