Howards slipping Nuclear power into his comments also.
An interesting issue as we have:
a) The Science behind the IFR reactor + reserves in the ocean to power us for 10,000+ years. On the basis that we solve the fission problem we have a much better method for producing energy later on. If we develop nanotubes to a decent enough point then theoretically we will build a space elevator which would allow us to dump the waste into space also.
b) Large risks with accidents, though some opinions are ill informed on the issue, and also the social considerations (i.e. Weapon manufacture by the government, arms race within our region).
I guess from the scientific point of view: It's cheaper than CCS (bury the CO2) and Wind/Solar as they require a Gas backup, breeding reduces waste Half Lives to 500 years, modern emersion in glass and then buried 2km below the surface, Australia sitting on the world's largest cheaply accessable supply and the immanent threat of climate change it is an option to be considered. But poor because of the risks associated with accidents, the lenght of time required to manage the waste and the burden this will place of future generations, potential degredation of lands, plutonium production (below weapons grade but a crude weapon could be made).
As people in Australia don't want it, then we have to find other methods to reach our reductions targets.
