Cementation of liquid radioactive waste with high content of borate salts
There are physical and chemical methods which allow accelerating the processes of cement compounds setting and hardening for liquid radioactive waste with aqueous solutions of boron with low pH. Boron compounds with low pH are the main components of liquid radioactive waste which prevent fast hardening. In order to control the speed of cement solution hardening and to remove the components that prevent hardening it is proposed to use electromagnetic treatment of liquid radioactive waste in the vortex layer of ferromagnetic particles.
