DAMPING DEVICE FOR RELOADING CONTAINERS WITH FUEL ASSEMBLIES OF REACTOR PLANT (VERSIONS) Russian patent published in 2019 - IPC G21F5/08 

FIELD: power engineering.

SUBSTANCE: group of inventions relates to nuclear power engineering, to protective means used to prevent damage to containers during overload. Damping device comprises detachable body with end walls and damping units with anti-shock elements. Body is made in the form of two semi-cylinders. Damping units on the side inner surface of the body half-cylinders are grouped into the surrounding half-rings surrounding the container body, which are formed by the anti-shock elements separated into layers in the form of radially installed plate-like ribs with the specified plasticity and with oriented preliminary bending. Plate ribs are arranged with opposite preliminary bending. Damping units on end walls of the body half-cylinders are presented in layers separated by multi-row sets of plate-like ribs with preset ductility and with oriented preliminary bending. There is also a version of the shock-absorbing device.

EFFECT: group of inventions improves reliability of dampers at impact loads of different directions and simplifies loading of containers into appropriate damping device.
