Melting is one of the potential treatment methods for non-combustible waste based on its properties of solidified products, such as radionuclides confinement, mechanical strength, etc. The radionuclide behavior in induction heat melting and its products were examined, such as volatility, nuclide distribution in the product, and leachability in support of safety assessment of LLW disposal. Volatile nuclides such as C-14 and I-129 were confirmed to be released in off-gas in the melting operation. Cs-134 remained in the product. The other nuclides remaining in the product were confirmed to be distributed in metal and ceramic blocks, depending on the thermal properties of the nuclides. The leaching rate of the metal and ceramic blocks as measured to be adequate.
