Rapid vitrification of simulated HLLW by ultra-high power laser.

It is essential to treat high-level liquid waste (HLLW) in a secure and effective manner. As a result, we first propose rapid vitrification of simulated HLLW using an ultra-high power laser. First, a cured body with a mass of 24.4 kg was obtained by using ultra-high power laser sintering. Subsequently, four different locations of the curing body were tested and the measured performance indicators were all in accordance with the regulations. This demonstrates the potential of ultra-high power lasers in HLLW glass curing processes. [ABSTRACT FROM AUTHOR]
