Radioactive gas solidifying device

Creators

Description

Purpose: To efficiently solidify radioactive gaseous wastes released from nuclear facilities such as nuclear fuel re-processing plants. Constitution: Planer electrodes are arranged with a predetermined gap therebetween to the inside of a tightly closed vessel, the inside of which is de-pressurized by a pressure reducing device. Radioactive gases such as krypton 85 are injected from a radioactive gas supply device. By applying voltage of opposite polarities to adjacent electrodes respectively in the electrodes and colliding the ions of krypton 85 against sputtering electrodes, neutral metals released from the sputtering electrodes are deposited on the surface of the injection electrodes. This enables to solidify radioactive gases efficiently without increasing the volume of the radioactive gas solidifying device. Further, the storage volume for the radioactive gases can be reduced significantly. (Moriyama, K.)
