The use of getters to remove tritium and other gaseous impurities (especially H2, N2 and CO) from helium circuits in nuclear reactors has been investigated. The loading capacity of beds, containing small Cerium-Mischmetal chips has been tested for several typical conditions. The results show that it is possible to use getters to purify inert gas streams for given boundary conditions. High CO-levers, however, lead to a poisoning (passivation) of the getter materials. The effect of poisoning is cumulative. A mathematical model describes the behavior of CO in this kind of getter. Safety tests under possible accident conditions were made with the highly reactive Cerium-Mischmetal chips. The results show that there isn't a critical problem in using this material in the form of a chemical reactive getter bed near a nuclear reactor in the investigated range of accident conditions. |
