HOLDER FOR PLACEMENT AND STORAGE OF LIQUID SPENT NUCLEAR FUEL Russian patent published in 2019 - IPC G21F5/02 

FIELD: nuclear physics and equipment.

SUBSTANCE: use relates to nuclear industry. Encasement for placement and storage of liquid spent nuclear fuel (SNF) comprises housing divided by bulkhead into upper and lower parts, cover, SNF feed and discharge pipe, gas branch pipe, fuel union, gas union, biological protection and aerator. Cover has a sealing element. Gas socket is equipped with a sealing plug. Axes of tubes are offset, and channels of tubes communicate with each other through existing channel in bulkhead. Inlet of the gas branch pipe to the lower part of the body is arranged aside from the axis of the latter. Biological protection is made of two parts, the first one is installed in the upper part of the housing, it surrounds the upper part of the pipe for supply and removal of spent nuclear fuel and the branch pipe gas, the second one – in the lower part of the housing on the bulkhead between the lower part of the supply and withdrawal pipe SNF and the outlet of the branch pipe.

EFFECT: invention makes it possible to create a case of increased safety, capable to provide personnel protection during performance of works on liquid SNF loading.
