"this doesnt address the mining, processing, transportation of uranium - and the transportation and storage facilities required of it afterwards. There is quite a lot of co2 generated in all those steps. "

True- but nowhere near as much as is generated by coal or oil. If the cost of construction is figured in, both hydro and geothermal have high startup costs. To be fair, one has to look at the total lifetime costs for ALL the various forms of power production- and looking at the TOTAL cost, nuclear is still competitive. It takes a LOT more tons of coal"ore" per megawatt than it does uranium: AND I have yet to see the design for a coal "breeder" plant that produces fuel.

Nuclear is NOT the one-size fits all cure, by any means: but the radiation released by the burning of coal ( from NATURAL radioactives found in it) PER MEGAWATT is FAR above the expected ( WITH accidents) amount released by nuclear plants.
