NASA Successfully Tests New Nuclear Reactor For Future Space Travelers

An anonymous reader quotes a report from NPR: NASA and the U.S. Department of Energy say they have successfully tested a new type of nuclear reactor that could one day provide juice to colonies on other worlds. The reactor can power several homes and appears able to operate in harsh environments. The new reactor uses more-conventional uranium fuel. Using a "core" about the size of a paper towel roll, the reactor can turn pistons that can run a generator. The generator can put out about 10 kilowatts of electrical power -- enough to run a few small homes. Scientists believe it could run continuously for a decade or so, making deep space travel a lot simpler. They also gave it a catchy acronym: KRUSTY, which stands for Kilopower Reactor Using Stirling TechnologY. To see if it actually worked, scientists tested KRUSTY out in the Nevada desert on America's old nuclear test range. They put KRUSTY through its paces, culminating in a 28-hour test at full power. The team also simulated failures in KRUSTY's reactor components to show it wouldn't result in a meltdown on Mars. KRUSTY may find its way onto future space probes. Researchers say they might use an ensemble of four or five of the reactors to power colonies on the moon (which has 14-day nights, when the sun isn't available) or Mars.
