Modern generation 4 pebble bed reactors produce almost no waste, and the waste they do produce is incased in graphite witch doesn't break down even in seawater for a million years. Witch is longer than the activity of plutonium.
It is virtually impossible for a Pebble bed modular reactors, or PBMR to have a meltdown or leak enough radiation to require any onsite cleanup, even if there was a catastrophic failure and nothing was done, they would shut down on their own without the need for backup systems.
You could build ten PBMR's in an area the size of three football fields and they would produce over a hundred MW's each. That's enough power for 30,000 average homes each reactor.
We would have to have a Chernobyl worst case scenario every three weeks to equal the deaths from respiratory disease caused by fossil fuel burning power plants. Which would only be possible with first or second generation plants.
Had it not been for the no nukes movement the US would be oil independent and producing less than ten percent of the carbon emissions we produce now.
The environmental movement has done allot of goods things, but they sure screwed the pooch on this one. They've got to learn to separate facts from rhetoric and not consider everyone whom wants a decent lifestyle the enemy. It's time to tell them to sit down and shut up on this issue and give a green light to new nukes.
