FIELD: physics, nuclear physics.
SUBSTANCE: invention relates to nuclear engineering, particularly to mobile protective containers meant for transportation and storing spent fuel assembly. Container for transporting and storing spent fuel assembly contains a case with a base, lid and end damping devices. Inside the case is installed a gripping cover with the spent fuel assembly cowling with a lid. One of the damping devices is placed between the lids of the case and cowlings, the other is made in the form of damping elements, are evenly arranged between the cowling and the base. Cowling is evenly arranged and rigidly fixed on the outer diameter lengthwise forming damping elements. Each damping element cowling and base has a section of Ω shape. Container provides an increase in reliability while using, and particularly protection of the cover with spent fuel assembly from shock loads on the axial, and also in the radial direction without increasing the mass of the container and its internal volume.
EFFECT: increase in reliability while using, and particularly protection of the cover with spent fuel assembly from shock loads on the axial, and also in the radial direction without increasing the mass of the container and its internal volume.
