I think few know or understand this- Jigar Shah (@JigarShahDC), after being a part of the driving success in solar pv scaling, turned his eyes to see how he could do the same for advanced nuclear. He saw the chicken-and-egg scenario of the complete lack of nuclear fuel supply chain and had the vision for funding both sides of the equation-- fuel enrichment on one side and companies that have demand to buy and fab fuel on the other -- to unlock development. The structural issues of the Loan Programs Office made this challenging to accomplish during his time but i still believe this is the best way to get fuel (fresh fuel anyway) in America going again. At Oklo we are uniquely interested in buying a bulk of fuel because unlike design firms, where generally the utility would own/operate and buy fuel, we plan to own and operate a whole fleet and buy our own fuel. Another thing that was challenging is that the most compelling cost numbers for SFR reactors are not publicly available for verification, although good cost analyses can and have been performed. Metal cooled fast reactors have something like 500 reactor-years of operational history. At least now, the Meta announcement shows the dominance of this design type (Terrapower and us). On another note, related to our recent tweet exchange, it is strange the narrative around us and the DOE and NRC. We took our lumps for leaning in before anyone else on the non-LWR reactor side with the NRC. When the NRC denied our application (out of process and suddenly) we did not even formally respond for our side of the story-- we literally just got right back to meeting with them to submit again. We had a successful readiness review with NRC for our Aurora plant last year just about the time we were selected for the DOE Reactor Pilot Program. We were weeks away from that application submittal which NRC already said had no gaps to successful acceptance. The DOE too, has a long and successful history of building and regulating nuclear plants. And now, we hope to be part of forging an interesting future where both DOE and NRC play crucial roles.

Oklo x Meta. @WIRED reports that @Meta is paying up front to support Oklo’s nuclear fuel procurement, which is one of the largest commitments from a hyperscaler. Why does this matter? This prepayment can help move new energy capacity forward by injecting additional clean power (paid for by Meta) into the grid.

$OKLO ⚛️ “We’re not even at the start of the game yet. We’re still in warm-ups.” That’s @jakedewitte, CEO @oklo at #CES2025 with @JobsOhio . Standing room only. Here’s what he revealed: ⚡ SMR → 75MW, agile deployment, learning by doing 🏗️ Material efficiency → less steel, copper and concrete per MWh than any other energy source 🔥 Sodium-cooled reactors → historical technology with proven operational superiority 📍 Ohio → “There’s nothing like it in the entire country” – full nuclear hub under construction 🎓 Multi-million dollar investment at Ohio State University to create a standalone nuclear engineering department 🧩 The only platform covering: fuel manufacturing → power generation → workforce training The gap with competitors? It’s only getting wider. 🏎️ Think of it this way: Imagine switching from a giant 1970s supercomputer to a modern, agile cloud server network. That’s exactly what Oklo is doing to the power grid. No more building monuments over 10 years. They’re deploying an intelligent, powerful network. They’re not building power plants. They’re building the energy infrastructure of the future. And Ohio is becoming their HQ. 📺 Watch the full CES panel 👇 #OKLO #Nuclear #SMR #CES2025 #CleanEnergy #Ohio

Radioisotopes have hundreds of uses and can be found in countless products we use every day. Take these five for starters. energy.gov/ne/articles/5-rad…

On @CNBC, Oklo CEO Jake DeWitte discussed how advanced nuclear can take advantage of additional fuel options in the near term and why surplus plutonium matters now: “It’s really a bridge fuel… a way to kick-start the build-up of advanced nuclear.” Last week, Oklo and Los Alamos National Laboratory completed a multi-day fast-spectrum plutonium experiment, generating data to support the use of surplus plutonium as a bridge fuel for commercial advanced reactors, including Oklo’s.
