FIELD: nuclear physics and equipment.

SUBSTANCE: invention relates to nuclear power engineering, in particular to the management of spent nuclear fuel. Ampoule for the spent fuel assembly contains a cylindrical body with a bottom in which a bundle of fuel rods of the spent fuel assembly is placed, and a lid entering the neck of the body with a clearance in the form of a labyrinth seal and configured to be locked by means of a locking device in the form of a spring split ring. To orient the ampoule, six vertical grooves are positioned at the top of its body to position the ampoule in the device for opening the lid.
