It is thought that a generated ruthenium compound grows from a high level radioactive liquid waste into RuO $_{2}$ crystal by reacting to raw materials for the vitrification process. In this study, the generation reaction to RuO $_{2}$ was confirmed by heating Ru-La-Na mix nitrates and the raw materials.
