CONTAINER FOR STORAGE AND SHIPMENT OF RADIOACTIVE MATERIALS Russian patent published in 2001 - IPC

FIELD: handling of radioactive materials. SUBSTANCE: container has case, cover, inner and outer shells that form shell-to-shell and shell-to-case spaces filled with neutron-absorbing liquid. Top part of outer shell mounts valves provided with nozzles arranged along outer shell of container. Valves are designed to evacuate steam formed during liquid boiling from spaces and to cool down the outer shell. Drain hole provided at bottom of space is closed with easy- melting plug. In the event of fire plug melts and liquid flows out of space through open drain hole. This slows down heating of container due to air cushion formed in the process thereby extending safe time for container under fire conditions. EFFECT: improved safety of container in emergency situations. 1 dwg
