Division Spotlight
Aerospace Nuclear Science & Technology
Organized to promote the advancement of knowledge in the use of nuclear science and technologies in the aerospace application. Specialized nuclear-based technologies and applications are needed to advance the state-of-the-art in aerospace design, engineering and operations to explore planetary bodies in our solar system and beyond, plus enhance the safety of air travel, especially high speed air travel. Areas of interest will include but are not limited to the creation of nuclear-based power and propulsion systems, multifunctional materials to protect humans and electronic components from atmospheric, space, and nuclear power system radiation, human factor strategies for the safety and reliable operation of nuclear power and propulsion plants by non-specialized personnel and more.

The oxide mixture MnO2/Ag2O has been identified as one of the best materials to oxidize hydrogen under ambient temperature and atmospheric pressure conditions. Studies have been carried out within the scope of the mitigation of hydrogen risk in fusion reactors and the optimal composition of this mixture has been determined by Chaudron as MnO2/Ag2O 10% wt. Using Maruéjouls' experiments, a model, previously developed to explain the oxidation of hydrogen by copper oxide for helium purification purpose, has been adapted and its simulation capability tested. To achieve this point, an exploratory experiment with a thin MnO2/Ag2O bed has been carried out under low hydrogen initial concentration (130 Vppm) in order to simulate tritium degassing. Although a very good global agreement between the calculations and the experimental points, the model is unable to account for the behaviour of hydrogen breakthrough at the beginning of the experimentation. Thus, enhancements of this model are presented in this paper. Finally, Scanning Electron Microscopy (SEM) analyses confirm the coherence of some assumptions used to solve the model equations.
