摘要： An adsorbing material comprises a porous body having larger pores of a mean pore diameter of 200 to 2000 Å and smaller pores of a mean pore diameter of 40 to 200 Å on the surface of the larger pores. The porous body being impregnated with a metal such as silver or copper, or a salt thereof such as silver nitrate. This material has excellent adsorbing performance for iodine and/or organic iodine compounds under any degree of humidity. It may be made by making particles having the smaller pores and the bonding of these particles together. e.g. by sintering.

摘要： An inorganic adsorbent comprising a porous titanium metal and titanium oxide sintered and impregnated on the surfaces of micropores of the porous titanium metal can be produced by impregnating the porous titanium metal with a titanium alkoxide solution, followed by hydrolysis and oxidation to give titanium oxide, and can be used for selectively removing transition metal ions in a water coolant of nuclear reactor.

摘要： A method of solidifying a radioactive waste of an atomic power plant, for example, begins with concentrating the liquid waste to powder or pellet form to reduce its volume. Prior to reducing its volume, an estimation is made of what the concentration will be once the liquid waste is converted into powdered or pelletized form. The powdered or pelletized waste is charged into a container, and a solidifying agent is poured over the contents to form a solidified body. The solidifying agent is prepared to have a desired coefficient of distribution that is determined in accordance with the estimated concentration of the reduced volume solidified waste so that the amount of leaching of the solidified body that is produced will be less than or equal to a predetermined value, such as the known value of leaching for a conventional cement-solidified waste that is not processed to reduce its volume before being solidified.
