process for the decontamination of gaseous products of a reatto king fusion

摘要

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