The principle and superiorities of glass-solidification technology for medium-and low-radioactive solid wastages have been expounded

the structure

working principle

and corresponding strong and weak points of glass-solidification facilities at abroad

including fuel type smelters

joule heating smelters

induction heating smelters

as well as plasma torch and electric arc(plasma arc) smelters

being comprehensively analysed

the glass-solidification technologies suitable to low-and medium-radioactive solid wastages of nuclear power plants

such as selecting incineration glass-solidification or direct glass-solidification mode

have been put forward.
