Pressure-concentration-temperature characterization of St909 getter alloy with hydrogen

摘要: Abstract One of the major issues related to next generation fusion reactors is tritium recovery and recycling from tritiated water. Among various approaches proposed, chemical dissociation water over active beds based on reactive alloys appears be a promising solution. It enables, in fact, safe by exploiting relatively high equilibrium pressures, even at low concentrations operating temperature, selected alloys. This paper presents results pressure-temperature-composition measurements carried out ZrMnFe alloy, named St909, candidate for such an application. Equilibrium isotherms have been determined between room temperature 400 °C hydrogen concentrations, higher exploring bi-phasic region. Sieverts' law obeyed concentration range, H A ratios less than 0.03.
