FIELD: power industry.
SUBSTANCE: fuel core includes assembly of coaxially arranged fuel pellets (1) made from fissile material, and heat-conducting gaskets (2). Each gasket (2) is installed between adjacent fuel pellets (1). Gaskets are also installed on end surfaces of the first and the last fuel pellet (1) of assembly. Thickness of fuel pellets is less than their diametre. Thickness of gaskets is less than thickness of fuel gaskets. Fuel pellets and gaskets can have the same diametre. Diametre of heat-conducting gaskets can exceed diametre of fuel pellets at least by the value of radial gap between surface of fuel pellet and inner surface of cover (3) of fuel cell. Gaskets are made from alloy on the basis of molybdenum enriched at least with one of isotopes: Mo92, Mo94, Mo98, Mo100, or from chrome alloy.
EFFECT: improving reliability, safety and power efficiency of fuel cores of fuel cells and nuclear reactor as a whole.
