PROCESS FOR CLEANING THE EXHAUST GAS OF A FUSION REACTOR

摘要

The exhaust gas of a fusion reactor contains, besides non-burnt fuel (tritium and deuterium) and the "ash" of nuclear fusion and helium, a number of impurities with the radioactive tritium chemically bound to them. In order to clean the exhaust gas both the elemental and the chemically bound tritium fractions have to be separated. According to this invention separation is achieved exclusively by physical and catalyzing process components, namely a palladium/silver permeator, a CuO/Cr2O3/ZnO catalyst bed and a further palladium/silver permeator containing a nickel/aluminum oxide bulk catalyst.
