FIELD: energy.
SUBSTANCE: minute particle of a nuclear reactor contains a fuel microsphere of fissile material and a multilayer protection coating consisting of serially applied on the microsphere layers. Fuel microsphere is hollow with a diameter of cavity equal to 0.1-0.5 diameter of the microsphere and contains getters of fission products. Cavity contains aluminosilicate compact. Used as a getter there are compounds of tantalum, titanium, zirconium, barium, cerium, lanthanum and niobium, as well as a mixture of cerium, lanthanum and thorium.
EFFECT: invention can be used in nuclear reactors used both for vehicles and stationary power plants, particularly in spaceworthy high-temperature reactors.
