Recent developments in nuclear energy will supposedly make it cheaper and safer to use. From mini nuclear power plants that do not contain weapons-grade material or moving parts, to thorium-based nuclear power plants, these new technologies are promising alternatives to today’s monsters. Regarding the mini nuclear power plants, it would be interesting to see exact numbers regarding how much feedstock would be required to run one of these mini nuclear power plants, who will remove the waste, and how much waste would result from these mini nuclear power plants. However, the numbers below look promising.  From the guardian.co.uk, UK:

Nuclear power plants smaller than a garden shed and able to power 20,000 homes will be on sale within five years, say scientists at Los Alamos, the US government laboratory which developed the first atomic bomb.

The miniature reactors will be factory-sealed, contain no weapons-grade material, have no moving parts and will be nearly impossible to steal because they will be encased in concrete and buried underground.

.       .       .

The reactors, only a few metres in diameter, will be delivered on the back of a lorry to be buried underground. They must be refuelled every 7 to 10 years. Because the reactor is based on a 50-year-old design that has proved safe for students to use, few countries are expected to object to plants on their territory. An application to build the plants will be submitted to the Nuclear Regulatory Commission next year.

‘You could never have a Chernobyl-type event – there are no moving parts,’ said Deal. ‘You would need nation-state resources in order to enrich our uranium. Temperature-wise it’s too hot to handle. It would be like stealing a barbecue with your bare hands.’

Other companies are known to be designing micro-reactors. Toshiba has been testing 200KW reactors measuring roughly six metres by two metres. Designed to fuel smaller numbers of homes for longer, they could power a single building for up to 40 years.
