<P>PROBLEM TO BE SOLVED: To provide physical means for performing separation condensation of a radioactive material emitted from a nuclear reactor building to a drainage system in the surroundings by fusion of nuclear fuel to be solidified without using a filter medium and adsorbent, and to further provide a system for separating salt etc. ionized by water from a solidified body to perform separation recovery of an insoluble radioactive material. <P>SOLUTION: Inert gas containing the atmosphere is blown in as air bubbles from the bottom of a contaminated water tank to separate moisture of the contaminated water as water vapor. The water vapor is emitted in the atmosphere through a filter installed at a flue 4, however, a nonvolatile material (containing ions and salt) contained in the contaminated water is condensed in a tank. By a system, air-drying is attained in a closed space by continuing ventilation from a hollow tube to the condensed nonvolatile material to obtain solidification containing salt and the radioactive material. By a contaminated water processor, demineralization is further attained by stabilizing structure of the solidified body by a solidification material and immersing the structure in water again. <P>COPYRIGHT: (C)2013,JPO&INPIT |
