Yellow phase components and platinum group elements are expected to increase in high-level liquid waste generated when spent high-burnup fuel and MOX fuel are reprocessed. We have been developing a glass matrix that can vitrify these waste liquids since FY2019, and we will report on the results in FY2022.
