RADIOACTIVE WASTE STORAGE Russian patent published in 2014 - IPC B09B1/00 

FIELD: ecology.

SUBSTANCE: proposed radioactive waste storage (RWS) comprises a foreshaft 1, fixed with the steel shell 2, the well 4 drilled through this foreshaft 1 in rock mass 3, cased with the metal casing 6 with the bottom 7, the thermoinsulator 11 of inert waterproof and heat-resistant material, located on the inner generant of the metal casing 6, the external engineering protective barrier 9 with the lower protective screen 10 of bentonite-cement monolith, the internal engineering protective barrier 12 with upper protective screen 13, the aggregate state control system 14 of the material of the internal engineering protective barrier 12, made of pipes 15, tripping column 16 with containers 17, 18 placed on it with RWS, the radioecological monitoring system 20 and the lid 21 of the casing 6. The bottom 7 is provided with alighting bearing-centring hubs 8. The external engineering protective barrier 9 is created by grouting the annulus. The internal engineering protective barrier 12 with the upper protective screen 13 is formed inside the metal casing 6 with inert material which is solid in natural conditions, but able to change its aggregate state (solid-liquid) under the thermal effect.

EFFECT: invention improves environmental safety, area usage factor of land allocation intended for RW storage, increases the amount of waste of increased activity in the storage, reduces the labour intensity of RW storage decommissioning at the end of its period of use.
