"A good clean pebble bed system, along with a good breeder...."

"Of course if we had a billion or two people offplanet, that would help greatly."

Maybe if we just got rid of some of them breeders, we wouldn't have the billion or two extra people laying around! lol..

Seriously, if there was an eruption and magma did get to the waste, isn't the heat intense enough to destroy much of the radioactivity? I thought that's how DU was depleted. Obviously I don't understand the time scales involved and am glossing over the possibility of explosions spreading the waste.

Sorry, never had to take chemistry and am just wondering aloud.
