24 h Continuous Process of Vitrificating Simulated HLLW at Cold Crucible Induction Melter Prototype

A cold crucible induction melter (CCIM) prototype was established in CIAE. To test the performances and matching of the equipments and evaluate the performance of simulated glass product, the CCIM test system was operated continuously over a time period of about 24 hours. During the test, the chemical reagent which included all the waste compositions and frit composition was pre-mixed and added into the CCIM. The results show that the equipment operation parameters are stable and melting temperature is controlled at (1200±50) ℃, feeding rate is at 6-10 kg/h. The main performance results of the glass produced in the process satisfy the requirements in China industry standard (EJ 1186—2005).
