【 摘 要 】

A fusion process based on low-frequency induction heating has been developed to treat mixed radioactive waste and produce biphasic glass/metal canisters compatible with a storage in a geological repository. The direct transfer of inductive power to the metal load ensures that fusion occurs directly in the final container and avoids a pouring stage. A thermal equilibrium develops during fusion between the power transmitted by induction and the power evacuated in the furnace's cooling circuits. The generator's electrical parameters are used to determine the amount of metal present in the canister.
