Commercial nuclear innovation "new space" age
In early 2006, a start-up company launched a small rocket from a tiny island in the Pacific. It exploded, showering the island with debris. A year later, a second launch attempt sent a rocket to space but failed to make orbit, burning up in the atmosphere. Another year brought a third attempt—and a third failure. The following month, in September 2008, the company used the last of its funds to launch a fourth rocket. It reached orbit, making history as the first privately funded liquid-fueled rocket to do so.

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.
