'The Next Nuclear Plants Will Be Small, Svelte, and Safer'

"A new generation of reactors will start producing power in the next few years," writes Wired, addingi that "They're comparatively tiny -- and may be key to hitting our climate goals."

For the last 20 years, the future of nuclear power has stood in a high bay laboratory tucked away on the Oregon State University campus in the western part of the state. Operated by NuScale Power, an Oregon-based energy startup, this prototype reactor represents a new chapter in the conflict-ridden, politically bedeviled saga of nuclear power plants. NuScale's reactor won't need massive cooling towers or sprawling emergency zones. It can be built in a factory and shipped to any location, no matter how remote. Extensive simulations suggest it can handle almost any emergency without a meltdown. One reason is that it barely uses any nuclear fuel, at least compared with existing reactors. It's also a fraction of the size of its predecessors.... Perhaps most importantly, small modular reactors can take advantage of several cooling and safety mechanisms unavailable to their big brothers, which all but guarantees they won't become the next Chernobyl... Yet this small reactor can crank out 60 megawatts of energy, which is about one-tenth the smallest operational reactor in the U.S. today....

But small reactors will still need to prove they can be cost-competitive, says Steve Fetter, a professor of public policy at the University of Maryland. With the price of renewables like wind and solar rapidly falling and ample natural gas available, smaller, svelter reactors may never find their niche. Especially if a prime motivator is climate change, whose pace is exceeding that of regulatory approvals. "I am skeptical of the ability to license advanced nuclear reactors and deploy them on a scale that would make a difference for climate change," adds Fetter. "But I think it's worth exploring because they're a centralized form of carbon-free electricity and we don't have a lot of those available." At least in the US, it might be the only way nuclear power gets another chance.

NuScale Power has already secured permission to build its first 12-reactor plant at the Idaho National Laboratory, supplying power to Western states "as soon as 2026," according to the article. And they're not the only company pursuing smaller nuclear plants.

"Earlier this month, a secretive nuclear startup called Oklo unveiled Aurora, its 1.5-megawatt microreactor, and announced it had received a permit from the Department of Energy to build its first one at the Idaho National Lab."
