PROBLEM TO BE SOLVED: To provide an absorption filtration material for simplifying regeneration of an electrolyte melt by selectively adsorbing Cs in the electrolyte melt comprising mixed salts of chloride system, for example, Cs that is FP remaining in the used electrolyte melt of chloride system.SOLUTION: The absorption filtration material performs selective absorption of fission products (FP) accumulated in the used electrolyte melt of chloride system. The absorption filtration material is glass or crystallized glass comprising FeOas an essential element, wherein FeOis 1-50, POis 30-80, AlOis 0-30, TiOis 0-50, ZrOis 0-5, RO(LiO+NaO+KO) is 0-40, RO(MgO+CaO+SrO+BaO+ZnO) is 0-60, and RO+R'O≥1. The softening point of the glass as a precursor of the glass and the crystallized glass is 450°C or more. |
