TRISO Fuel

“A triso-fueled, graphite-moderated, helium-cooled reactor of the geometry that we've built it here is just about as safe as humanity knows how to build a nuclear reactor.”

“What we're doing is these tiny poppy seed size kernels of fuel. There are about a hundred and twenty million of them. For a hundred kilograms of uranium and this is all in a core that's, you know, only four feet in diameter.”

“The temperature limit of the fuel becomes this extremely high value, and you can go to about 1600 Celsius before there's an appreciable failure rate of the ceramic coated fuel. So what it means is you can't melt down the fuel.”
