Mini nuclear reactors to power remote areas

It's the size of a shed, but you're not likely to find it in any backyard.

Using technology originally developed by scientists at Los Alamos National Laboratory in New Mexico, Hyperion Power Generation is creating mini nuclear fission reactors that will provide electricity and hot water to remote locations, nearly all outside the United States.

"There is a strong humanitarian bent to these reactors," said John "Grizz" Deal, Hyperion's CEO. "This was invented to provide electricity and hot water to remote locations, where people might not have electricity or clean water."

Deal says that Hyperion has already received more than 100 orders for the $25-30 millions reactors, which are sealed shut with concrete and have no moving parts. The reactors are designed to generate electricity or boil water clean after being hooked up to water piped near their 500-degree surfaces.

Standard nuclear fission will generate the heat. As the uranium inside the reactor breaks apart naturally, it creates heat and sends neutrons (tiny particles that exist in the nucleus of atoms) blasting out. If those neutrons hit other uranium atoms they break apart as well, creating even more heat and more new neutrons.

Many modern nuclear facilities moderate the reaction with control rods that, when inserted into the nuclear fuel, slow down neutrons. But control rods can fail and reactors can overheat if not properly managed. Hyperion eschews control rods by adding hydrogen atoms to the uranium, which take the place of the control rods to moderate the reaction.

"Since the fuel and the moderator coexist in equilibrium, it's impossible for the chain reaction to go faster than we want it to," said Deal. "What we've done is essentially turned uranium hydride into a battery."

It's a battery you wouldn't want to touch. Using propriety technology, Deal says that they can transfer over 99 percent of the 500 degrees produced inside the reactors to the surface of the sealed concrete container. Whoever buys the reactor will pipe water past the those 500-degree thermal conductors, boiling the water to purify it or produce steam that would power nearby generators.
