Abstract

When SA is generated, a large amount of hydrogen is generated due to the reaction between water vapor and zirconium. A PA is installed in the containment vessel as a countermeasure against hydrogen, but there are concerns about the effects of water vapor and methyl iodide.A silver zeolite AgX with excellent methyl iodide adsorption performance was developed and its performance was evaluated together with PSI. It was found that AgX can remove methyl iodide and hydrogen simultaneously. The properties of AgX are expected to play a supporting role for PAR.We also evaluated the hydrogen handling capacity of AgX under certain conditions and found that 1 kg of AgX can handle 0.207 kmol of hydrogen.
