Synroc
From Wikipedia, the free encyclopedia
Synroc, a portmanteau from "synthetic rock", is a possible means of safely storing and disposing of radioactive waste. It was invented in 1978 by a team led by Dr Ted Ringwood at the Australian National University, with further research being undertaken in collaboration with ANSTO. Unlike borosilicate glass, which is amorphous, Synroc is a ceramic that incorporates the radioactive waste into its crystal structure. Although it has not yet experienced commercial use, in April of 2005, the process was chosen for a multi-million dollar "demonstration" contract to eliminate five tonnes of plutonium-contaminated waste at British Nuclear Fuel's Sellafield plant, on the northwest coast of England.
