Flammability hazards of typical fuels used in wind turbine nacelle

2. 'Waste' space

If you dig a hole to put the spent fuel in, you don't actually have to pay a million years' rent in advance - or ever, it's well below the biosphere. However, the longer the delay on building these deep depositories, the better. Nature managed to build and operate a number of natural fission reactors in Gabon, Africa, about two billion years ago. They ran, on and off, for millions of years. Although they were under a rainforest, the fission products have only moved a few metres since then. The casks now used can quite safely store the 'very lightly used' fuel. It's not 'spent' -when we're ready to use it, 99% of the energy is still there. Reactors capable of doing this are already being planned, or are operating, in the US, China, India, Russia, and Canada.
