Vitrification of simulated high-level liquid waste by laser

A safe and efficient method is necessary for the treatment of high-level liquid waste (HLLW). Therefore, we propose for the first time the use of laser to simulate the glass curing of HLLW. In this paper, borosilicate glasses containing 16% simulated oxides were successfully sintered by laser at different temperatures (1050 °C–1200 °C). A series of properties of the obtained cured bodies were analyzed. The results show that the cured body can be prepared above 1100 °C to meet the requirements. This demonstrates the potential application of lasers in the treatment of HLLW glass curing.
