FAST NEUTRON NUCLEAR REACTOR FUEL ELEMENT Russian patent published in 2016 - IPC G21C3/02

Abstract RU 2589010 C2

FIELD: nuclear power.

SUBSTANCE: fast neutron nuclear reactor fuel element has a shell made from spacing and smooth parts, which are connected through the lower reflector. Core from fissile material pellets is covered by foil from high-melting point material, for example from molybdenum, and the upper reflector forms a single assembly unit with a washer made from high-melting point material. Ribs or wire are used as a spacer, they girdle spirally the outer surface of the fuel element cladding.

EFFECT: to reduce hydraulic resistance of the fuel element.
