Nuclear wastes are neither particularly hazardous nor hard to manage relative to other toxic industrial wastes. The amount of radioactive wastes is very small relative to wastes produced by fossil fuel electricity generation. Safe methods for the final disposal of high-level radioactive waste are technically proven.
There have been several proposal for regional and international repositories for disposal of high-level nuclear wastes and several projects are being investigated.
There are a number of pervasive myths regarding both radiation and radioactive wastes. Some lead to regulation and actions which are counter-productive to human health and safety.
Synroc is basically a ceramic made from several natural minerals which together incorporate into their crystal structures nearly all of the elements present in high level radioactive waste. Recent developments are of specialised forms to immobilise plutonium, and of composite glass-ceramic wasteforms.
Decommissioning costs for nuclear power plants, including disposal of associated wastes, are reducing and contribute only a small fraction of the total cost of electricity generation. Proven techniques and equipment are available to dismantle nuclear facilities.
