Title: Simple storage facility for radioactive matter
Inventor: YOKOYAMA TAKESHI
IPC: G21F9/36
Filed: 1998-07-08
Abstract: PROBLEM TO BE SOLVED: To reduce costs for construction and removal by being constituted of an upper radiation shield that covers the space above housing containers which stow radioactive matter and side radiation shields that are located so that can surround the containers from their side and can move freely and that form a radiation shield structure together with the upper radiation shield. SOLUTION: A ceiling shield 23 is provided in the space above pillars 21 erected on the ground 1, a storage space 25 is secured in the space below the ceiling shield 23 and housing containers C are placed at appropriate intervals in the space 25. Then, side radiation shields 27 are located to surround the group of the housing containers C. The radiation emitted from the housing containers C is blocked out by the side radiation shields 27 surrounding the containers C and the ceiling radiation shield 23. Moreover, the heat of the housing containers C is removed by the air coming in and going out at interstices. Since the pillars 21 are strong enough to support the weight of the ceiling shield 23, it is not required to shield from radiation and even the small shape and size may be effective a facility can be easily removed.
