FIELD: physics, atomic power.
SUBSTANCE: invention relates to nuclear engineering and can be used to produce fuel elements for slow and fast neutron reactors. A fuel element for a nuclear reactor, having a sealed shell in which there is a fuel kernel and voids, further includes a working fluid with a melting point and a boiling point which correspond to the operating temperature range on the periphery of the shell and at the centre of the fuel kernel, and the fuel kernel contains nuclear fuel of a capillary structure with interconnected porosity.
EFFECT: high heat removal in a fuel element of a nuclear reactor, which significantly improves performance of fuel elements of nuclear reactors.
