Can You Dig It? an Archaeologically Fertile Area of the Middle East Finally Opens Up

THE CRUX Can You Dig It? An archaeologically fertile area of the Middle East finally opens up. Ask Discover Why aren’t we using thorium Q in nuclear reactors, given the possibility of a meltdown is nearly zero and the waste cannot be used to make bombs? — Dennis Dorando Concord, Calif. In a word: precedent. A It’s certainly possible to base nuclear reactors around thorium, as opposed to the most commonly used element, uranium. And thorium reactors likely would be somewhat safer because of thorium-based fuel’s greater stability versus uranium-based fuel, with the added Michael Danti, the archaeologist leading the benefit of not producing as much effort to search the isolated Kurdistan region, stands atop a dig near Gird-i Dasht thought nuclear bomb fuel.
