Treatment
- Most common initial treatment of waste is vitrification.
–Waste is first mixed with sugar and then passed through a heated tube to de-nitrite the material.
–This material is then fed into a furnace and mixed with glass.
–The molten glass mixture is poured into steel cylinders and welded shut.
- Mid level active waste is commonly treated with ion exchange
- Process reduces the bulk volume of radioactive material.
- Typically, mixed with concrete for a solid storage form.
- Synroc is a new method for storing nuclear waste developed in 1978 by Ted Ringwood.
- Attempts to hold radioactive material in a crystalline matrix.
- Currently in use for military waste management at Savannah River Site.
- Can hold 50%-70% volume of waste.
