a trapping material that is injected into the trapping vessel and traps iodine ions generated by decomposition of the organic iodine;
a first storage vessel containing the organic iodine remover;
a second storage vessel containing the trapping material;
a third storage vessel containing the organic iodine remover;
a first injection pipe that connects the first storage vessel to the trapping vessel;
a second injection pipe that connects the first storage vessel to the second storage vessel; and
a third injection pipe that connects the second storage vessel to the third storage vessel,
wherein the trapping material is a metal or a metal compound.
