FIELD: power engineering.
SUBSTANCE: invention can be used in production of tubular fuel elements of teaching reactors running on fuel of high and low concentration shaped, preferably, to hexahedron. Proposed process comprises making of prefabricated blank. The latter is composed of front plug, fuel core with fissionable material and rear plug enclosed in shell from thermally-hardenable aluminium alloy. Said prefabricated blank is subjected to hot forming, drawing of formed pipe and quenched. Forming of said blank is performed with application of lubricant, taper female die and movable conical needle. At first drawing pass, pipe is produced with equal wall depth over its length. Every drawing pass or set of drawing passes performed before heat treatment, is executed at total reduction at pipe centre not over 10% for not over 3 hours from the end of heat treatment in direction of forming.
EFFECT: perfected method.
