APPARATUS FOR SEPARATION AND RECOVERY OF TRITIUM AND COMPOSITE FUNCTIONAL SEPARATION MEMBRANE FOR SEPARATION AND RECOVERY OF TRITIUM

摘要

PURPOSE:To recover the tritium (T2) produced in a proliferation blanket through a simplified process, by reducing the T2O in a massive amount of gas into T2 through a specific composite functional separation membrane followed by passing this T2 through a metal (alloy). CONSTITUTION:One side of a porous glass film carrier ca. 1mm thick consisting mainly of SiO2 having penetrating holes with an average size of ca. 50Angstrom is carried with a ca. 5wt.% based on the carrier 11, of a reducing catalyst-carrying layer 12 consisting of a mixture of CuO, ZrO and Cr2O3, whereas the other side is carried and covered with a permeation film layer 13 consisting of e.g., Pd capable of diffusing and permeating T2 in the form of solid solution, thus constructing a composite functional separation film. Thence, the neutron produced by P-T reaction in the core of a nuclear fusion furnace is made to react with the blanket material in proliferation blanket section 2 to produce, for example, =90wt.% of T2O and a combination of T2 and 4He, which are then introduced into the separation membrane section 3 constituted of said composite functional separation membrane together with CO:7 and a sweep gas via a cooling device 5 to reduce the T2O into T2, and the T2 is penetrated through the membrane 13 via a vacuum exhaust system 9 to adsorb the T2 on a T2 getter 8 to accomplish recovery of the T2.
