    摘要： YThis invention concerns solidification products capable of immobilizing radioactive wastes containing water soluble solid components stably for a long period of time, as well as a process for producing the same, in which radioactive wastes are immobilized with an alkaline earth metal silicate compound and the alkaline earth metal silicate compound intakes the water content in the solidifying agent as the bound water to or a hydrate. High temperature and high humidity condition has been found to be necessary upon curing in order to take the water content as the bound water. This invention can provide solidified wastes with less development of detects such as open pores or cracks.

    摘要： A method for processing spent radioactive ion exchange resin formed in a nuclear power plant by a two-step pyrolysis method. First, the spent resin is heated at 350.degree. C. to decompose functional groups selectively. Then the base polymer, formed as residue, is decomposed at a temperature above 350.degree. C., e.g. 600.degree. C. After the thermal decomposition, exhaust gases which require a special exhaust gas disposal means, such as NO.sub.x and SO.sub.x can be reduce to below 1/20.

    摘要： An apparatus for isotope exchange reaction is used in an apparatus for removing tritium in heavy water-moderated nuclear reactors or heavy water production plants, and comprises a plurality of mist generators and a plurality of reactor columns, the mist generators and the reactor columns being alternately arranged and connected to one another successively in the alternate order. An ultra-sonic generator is provided each in the mist generators. A hydrophobic catalyst bed and a mist separator are provided each in the reactor columns. Water containing hydrogen isotopes to be removed is led into the mist generators to form mists. Mists of the water are supplied into the reactor columns together with hydrogen gas and isotope exchange reaction is carried out in the hydrophobic catalyst beds.

    摘要： N-.beta.-(aminoethyl)-.gamma.-aminopropyltrimethoxysilane [NH.sub.2 (CH.sub.2).sub.2 NH(CH.sub.2).sub.3 Si(OCH.sub.3).sub.3 ] as a silane coupling agent and SiO.sub.(2-x) (ONa).sub.x/2 (OH).sub.x/2 as colloidal silica are mixed into a radioactive liquid waste containing sodium sulfate as a main component, coming from a boiling water-type, nuclear power plant as an effluent. The resulting mixed radioactive liquid waste is supplied into a vessel provided with a rotating shaft with blades. The rotating shaft is revolved while heating the radioactive liquid waste in the vessel, thereby making the radioactive liquid waste into powder. The resulting powder containing the silane coupling agent and the colloidal silica is shaped into pellets by a pelletizer. The pellets having a low hygroscopicity and a high strength are obtained.
