Aalo Atomics

Aalo Atomics – Austin, Texas-based advanced nuclear venture leveraging founder experience designing the DOE’s Gen IV microreactor, MARVEL, an advanced nuclear reactor developed at the INL, to expedite the design, review, approval and scaled deployment of a fleet of highly stable and safe commercial sodium-cooled microreactors optimized for use by data centers and others.

Gates’ TerraPower Advances the Natrium

Bill Gates' TerraPower has "broken ground" at the future site of the Natrium Power Plant, what will be an advanced nuclear power plant.   This follows the acceptance of TerraPower's Construction Permit Application for review by the U.S. Nuclear Regulatory Commission in May, 2024.

Bill Gates wrote about this ground-breaking in Kemmerer, Wyoming on his GatesNotes blog and he provided further background on his interest in advanced nuclear, which started as far back as 2008. It just so happened that when he fell in love with the density, inherent safety and superior performance of advanced nuclear power, he was able to afford to hire a team and launch TerraPower on his own.  It also didn't hurt that he happened to be buddies with Warren Buffet, the CEO of Berkshire Hathaway, the company that owns PacifiCorp, which owns a lot of struggling coal plants, so he was able to score a site on the property of a retiring coal plant, on which to plan to build his demonstration reactor.

In fact, advanced nuclear holds tremendous prospects for resurrecting the value of these ill-fated plants and the economic vitality of those regions suffering from the closures of coal, most of which are closing as a result of competition form cheap natural gas that is also better suited for being "dispatched," at a minute's notice, if, let's say, the wind stops blowing. As many as 80% of these plants could, according to a study done by the DOE, be converted to advanced nuclear plants cost-effectively, because they are reuse turbines, generators and even transmission lines that are already there. Taking what are currently brownfield sites with very little value because of the toxicity, health and carbon-impacts of coal and converting them to clean power plants that use advanced fission to generate both power and heat, is starting to look like a very lucrative endeavor.

No wonder Bill Gates has already invested over a billion dollars and has committed to putting billions more of his own funds into this venture. Being the sixth wealthiest person in the world gives him this option. And, if you think that, because you read a lot and you've had exeptional success with a software company, that you have what it takes to create the best advanced nuclear technology and believe that it will be rapidly adopted and deployed around the world and possibly put the remainder of the world's coal plants out of business, investing your billions into that makes total sense.

For the rest of us, however, investing into a venture fund like Nucleation Capital, which is dedicated to building a diversified pool of advanced nuclear ventures with various alternative designs, more than a few of which could find real traction within differing niches of the energy markets which also need power but may prefer a different configuration or set of features, may make more sense and pose considerably less risk. Especially when the fund provides low-cost participation, so that those of us not in the top ten wealthiest humans list, can access that fund without breaking the bank but nevertheless have a meaningful chance of participating in the growth of nuclear around the world.

A 70th Anniversary for Fission

70 years ago today, on December 20, 1951, the first Experimental Breeder Reactor (EBR-I, pictured below at left) came online at the Idaho National Laboratory to produce usable electricity through fission.  The reactor, initially used to power four 200-watt lightbulbs, was increased to power the whole facility on its second day. While small, the reactor provided scientists with the ability to do a lot of testing. These tests, both successful and unsuccessful, enabled a lot of other reactors, including the EBR-II and coming soon, the Oklo Aurora, to follow with considerable design improvements. In 1966, President Lyndon Johnson declared the EBR-I a National Historic Landmark.

The EBR-I was a liquid metal-cooled fast reactor that used a liquid sodium coolant which transfers heat much better than today's light water reactors.  The second Experimental Breeder Reactor (EBR-II), which operated from 1961 to 1994, ran for more than 30 years quite successfully. However the potential hazards of a sodium leak combined with water was a deterrent to the use of this type of reactor in a submarine. The Navy wanted to have nuclear-powered submarines and opted to use the pressurized light water reactor, that used sea water as its coolant. This choice influenced the later commercial adoption of water cooled reactors on land, even though there were risks associated with the need to replicate an underwater environment to cool the LWRs built on the land.

Which makes the 2020 submission by Oklo to the NRC of a 4th Generation liquid-metal cooled fast reactor not just historic but also somewhat ironic. It's taken 70 years and a catastrophic climate crisis to finally get back to basics, and reassess the potential of the metallic fuel, liquid-metal collant system that was initially deemed the superior choice for electricity generation on land.
