Design optimization of metal getter reactors for removing tritium from flowing gas streams

摘要: A reaction engineering approach was used to design a SAES St 198 metal getter reactor for glovebox detritiation system. The system will be decontaminate and decommission an Li(D, T)-contaminated previously in the U.S. nuclear weapons program. involved development of model that calculates breakthrough curves as function various physical parameters. Experiments involving flow deuterium nitrogen through small validated model. then investigate effects temperature, pellet size, diameter, volume on performance. resulting 7 cm diam. by 40 long cylindrical operates at 250 {degree}C, is filled with 5 kg as-received pellets. handles rate 100 L/min. An 909 upstream impurity removal water decomposition. cleanup mechanical are discussed. 14 refs., 6 figs.
