Apollo Atomics launches with $31M seed to shrink nuclear’s overlooked bottleneck


Nucleation's portfolio company, Apollo Atomics, emerged from stealth this week alongside an oversubscribed $31 million seed financing, with a thesis that targets a component most reactor developers leave alone: the steam generator.

Conventional steam generators are multi-story structures, hand-built on site, and they drive a substantial share of the size and cost of a nuclear plant. Apollo, an MIT spinoff founded by Assil Halimi and Drew Walker, has redesigned the component as a compact, factory-manufactured unit roughly the size of a person, threading coolant and water loops through a metal block laced with needle-thin channels for far more efficient heat transfer. The result is a steam system 20x smaller than conventional equivalents and an 80% reduction in overall plant size at the same power output.

Critically, Apollo pairs that innovation with proven pressurized water reactor technology, commercially available fuel, existing supply chains and familiar regulatory pathways. The company's fuel has achieved criticality at full power and it is now pursuing NRC commercial approval, drawing on more than fifteen years of MIT research and testing. Apollo is targeting deployment in under two years, against a conventional timeline of a decade or more, with three reactor sizes spanning 10 to 300 MW and commercial interest totaling 20 GW from data center builders, university campuses and industrial offtakers.

The round was led by FCVC, with participation from Nucleation Capital, Y Combinator, Telesoft Partners, Pelion VC, Alumni Ventures, Duke Capital Partners, Stanford University, the E14 Fund and others. Apollo's launch was covered in an exclusive by TechCrunch.

Blue Energy and GE Vernova Hitachi advance gas-plus-nuclear project in Texas

Nucleation's portfolio company, Blue Energy, has signed an agreement with GE Vernova Hitachi Nuclear Energy (GVH) that launches the next phase of their 2.5-gigawatt gas-plus-nuclear power plant in Victoria, Texas. The agreement advances engineering design, licensing and safety analysis for the project, ahead of a final investment decision expected in 2027.

The plant pairs two GE Vernova 7HA.02 gas turbines — roughly 1 gigawatt, powering a nearby data center from 2030 — with up to five GE Vernova Hitachi BWRX-300 small modular reactors adding another 1.5 gigawatts beginning in 2032.

Blue Energy's integrated approach to prefabrication, transportation and assembly, which the company calls the “Blue Way,” builds on the standardized, modular design of the BWRX-300, using off-site fabrication, innovative logistics and super-module assembly to improve schedule, cost and delivery predictability. CEO and co-founder Jake Jurewicz framed the goal as making nuclear “a financeable, repeatable product.”

The first BWRX-300 is currently under construction at Ontario Power Generation's Darlington site in Canada, with completion expected by the end of the decade, which will make it the first grid-scale SMR in the Western world.

A novel (and increasingly imminent) solution to nuclear waste

When Nucleation's portfolio company, Deep Isolation, choose in early 2025 to access the public markets to complete a reverse merger into a shell company and simultaneously raise approximately $30 million—their last tranche of capital—they did so with one big goal in mind: funding the costs to complete their full-scale test of their deep borehole nuclear waste solution.

Deep Isolation had been, by that point, developing this concept and testing aspects of their design for a full decade, having been founded in Berkeley, California in 2016 by the UC Berkeley physicist and MacArthur Genius Award-winner, Prof. Richard Muller, and his daughter, Elizabeth Muller, in an effort to provide a cheaper, easier and yet potentially permanent alternative solution for disposing and/or storing nuclear waste.

The only other waste solutions that have been developed and used for nuclear waste (post-cooling tank) include ground-level storage in dry cask containers in protected areas on the grounds of nuclear power plants (seen as temporary, not completely satisfactory but largely cost-effective), and below-ground mined repositories that are virtually impossible to site (think Yucca Mountain), are quite expensive, difficult and time-consuming to build and which would require being fully staffed and powered forever (needing electrical power for heat, lights, air circulation and ventilation, among other services, and requiring regulators to perform routine checks and security teams to provide protection around the clock, at enormous expense).

In contrast, the Deep Isolation solution leverages highly mature, deep-borehole drilling technology developed for the oil and gas extraction industry (which has now drilled hundreds of thousands of extractions boreholes) but modified so as to enable sealed stainless steel canisters of waste to be lowered into deep, horizontally-drilled boreholes and either termporarily or permanently sealed up, thereby minimizing ongoing costs.

It is an elegant and highly viable solution because the drilling technology exists to emplace those boreholes in layers of the earth's strata a mile or two underground that are highly stable. Deep Isolation has, in the interim ten years, been amassing patents and now has a portfolio of more than 100 patents protecting this waste storage solution. They have been working to educate potential customers about their solution, earning bits of revenue by developing feasibility studies with EPRI for the U.S. and European countries like the UK, Estonia, Solvenia and, through ERDO, Croatia, Denmark, the Netherlands and Norway. And, importantly, they have developed technology and provider partnerships with groups like Halliburton, Bechtel, Amentuk, NAK, Occlusion Nuclear Solutions and Westinghouse. These partners would do the hard work of the drilling, casing and emplacement—which they already know how to do—and Deep Isolation would continue to make sales and earn a premium as the technology developer and owner of the proprietary aspects of their solution. It's a highly workable solution.

Now that Deep Isolation is a publicly listed company (OTCQB: DBHL), there has been growing press coverage of their activities. We expect that, as word gets out, more investors and analysts will come to recognize that Deep Isolation has a very unique opportunity here to help address the nuclear waste issue. Furthermore, assuming their full-scale testing process is successful, there could be a sharp increase in revenues as orders are placed, which for this still small but highly innovative company, means that nearly all of their growth is ahead of them.

Fortune recently published an article by Jordan Blum, titled This nuclear startup and Halliburton repurposed oil-drilling tech in a bid to solve America's radioactive waste problem.  This title may give Halliburton too much credit but, thanks to its successful reverse merger financing, the company has the requisite capital to pay Halliburton to actually drill a new well at the larger diameter specified by the Deep Isolation design and deploy a full-scale test using the universal canister developed with the help of the U.K. government. Proving that they can actually store waste deep underground is the last hurdle anticipated to be covered before quite a few prospective customers could begin to place orders, according to company officials and others.

The Mullers moved on in 2024, having taken the company as far as they could, but Deep Isolation is now led by Rod Baltzer, the CEO since 2024 and the former COO, who is an experienced oil and gas executive. There could well be a little bit of trial and error completing this first true test of the technology, which must be drilled at about triple the standard fracking well size, yet those in the industry with expertise see no major barriers that would prevent their success, and Mr. Baltzer is up for the challenge.  Meanwhile, the real work is now happening at a time of intense and growing interest in deploying additional nuclear power as a solution to energy security, energy growth and concerns about carbon emissions and climate change, and the emergence of an easier, potentially cheaper and more flexible waste storage option can make those deployment decisions easier.

We are thrilled that Deep Isolation is finally going to be able to showcase a true demonstration of their solution and transition from a trickle of revenue—largely from feasibility studies and government grants—to actual orders in the hundreds of millions for their solution to be implemented both in Europe and in the U.S., where progress is being made in solving the nuclear waste storage impasse. The Trump Administration has already made noises about passing legislation that would enable each state to determine if they would like to host a waste storage facility. We think, placing nuclear waste deep underground in safe but cost-effective boreholes could be one of the most important technological steps forward that helps expand support for nuclear power while preserving our ability access to that used fuel material when we have better waste reprocessing capabilities.

~90% chance of a record-setting El Nino

The Strongest El Niño Ever

According to Dr. Zeke Hausfather, one of the world's leading climate scientists, based on the data we have so far and the analysis of that data by some 667 scientists evaluating global temperatures through some 14 different forecast models, not only is this year's El Niño likely to be the strongest ever recorded, it may even be the strongest by a truly "mind-blowing margins."

After all the scientists submit their models' estimates for what may happen during this year's El Niño event, the "multi-model" median stands at 3.6C, which is roughly 0.8C hotter than the prior world record of 2.75C. Previously, the largest jump up was only 0.5C.  Thus, the models are, collectively, predicting weather outside of the bounds of anything previously ever observed with global temperatures. Which means that we are headed into entirely unknown territory as a planet, that even the scientists who have been watching the global temperature trends worsening for years and decade, have never seen in their lives.

What Dr. Hausfather finds remarkable is not just the magnitude of the projected heat level but also the trajectory of how quickly it is developing.  What scientists are seeing in how 2026 global temperatures are progressing, as we enter the northern hemisphere's summer months, is that there is an explosive El Niño onset happening. As unusual as the present trajectory is towards El Niño intensity, in fact the 14 different models have unusually strong model prediction agreement. Given this, the models yield a ~91% chance of a record peak in the El Niño that make it highly likely to be the strongest El Niño ever observed.

This is all still a prediction but the patterns reported by the model are extremely disturbing and the signature of a climate pattern that is not good for humanity or the planet. We definitely need to be more organized around marshalling our response and preparing for a world with record high heat that impacts not just air temperature but also ocean warming.  We can't respond fast enough to this threat and we are clearly going to miss the world's ambition to reduce emissions by 50% by 2030.  But, even with our abject failure to meet our 2030 goals, the good news is that we might be able to meet our 2050 goals, if we can continue our current commercialization progress for next-generation nuclear, that can compete and win against fossil fuels.
