FIELD: power engineering.
SUBSTANCE: shell is fully or partially made of a composite material with a ceramic matrix containing fibres of silicon carbide (SiC) as reinforcement of the matrix and a phase-to-phase layer between the matrix and fibres. The matrix contains at least one carbide selected from titanium carbide (TiC), zirconium carbide (ZrC) or triple carbide of titanium-silicon (Ti3SiC2). The method to manufacture a shell of nuclear fuel includes, in particular, manufacturing of a fibre pre-mould, application of a phase-to-phase layer on it with chemical steam infiltration, application of the matrix.
EFFECT: reliable mechanical retention of products of nuclear fuel fission inside a shell during radiation, at the same time optimal transfer of heat energy to coolant is provided.
