A Ladies Luncheon discussion of nuclear!
Los Angeles is still reeling from a series of horrific fires that devasted multiple communities, particularly Palisades and Eaton in early 2025. Recent reports found that these fires caused between $28 and $54 billion in property damange, along with what may be $9 billion in related economic losses in LA County alone. The fires have caused a loss of almost 50,000 job-years in the region, reducing area wages, business income, and federal, state and local tax revenue.
Lack of rain, hotter and drier conditions and high winds helped fuel the fires while combating the fires was hindered by the excess heat and widespread shortage of divertable water resources. These are conditions that have been exascerbated by global warming, which is caused by humanity's growing carbon emissions from burning fossil fuels. Gigatonnes of these heat-trapping waste CO2 emissions have amassed within the atmosphere causing the planet to get warmer. Scientists now believe that we've exceeded 1.5°Celsius average increase or 2.7°Fahrenheit and the heating is continuing to rise at an accelerating rate.
While Los Angeles is working to recover, rebuild and repair, the question of how to begin to reverse the damage we're continuing to do to the climate remains. We know with total certainty that we must stop burning fossil fuels. But demand for energy is not just growing around the world, demand is surging—particularly due to AI usage. This means not only do we need to focus on building only new clean energy plants but we also need to replace the 80% of global energy still using fossil fuels with equivalent sources of clean power as well.
We've been building wind and solar as fast as possible but these have never been able to keep up with even the historically lower level of energy growth. Additionally, the enormous costs of "firming" all that dilute and intermittent power (i.e. adding batteries, duplicative generation, and other fossil back up for when the sun and wind aren't cooperating) have increased California ratepayer costs. Meanwhile, we are still reliant on burning fossil fuels for some 60% of our power here in California and new fossil plants continue to get built that lock in continued emissions for decades more, which is extraordinarily bad for our future.
We clearly need better solutions. From our perspective, the only good news on the climate horizon is that energy experts, tech hyperscalers, government officials, industrial companies and investors are increasingly recognizing the importance of nuclear power for addressing our energy and climate needs. Nuclear (fission) power produces massive amounts of energy with zero emissions and runs reliably 24/7 (except for refuelings). It also cleans the air (as it emits zero toxins, unlike coal and gas), it provides good-paying jobs and has one of the smallest possible ecologic footprints. Best of all, there's a race on to develop next-generation nuclear power plants that better meet our 21st century energy needs. (Nuclear fusion may play a role in the future but commercialization of that technology is still much further off.)
Nuclear power—and especially newer, advanced designs—has seen bipartisan support in the Congress since the Obama Administration. Both Biden and Trump have increased funding for development of next-gen nuclear and signed multiples bills to accelerate new deployments for energy security, for climate change and for national security goals. Public support for nuclear power is currently at its highest level in decades. Yet, support by men exceeds that of women overall. Among women, surprisingly, those most concerned about climate change, primarily progressive Democrats, report the least support for nuclear power. This appears to be a function of less awareness and knowledge about the technology and a residual sense that nuclear is dangerous, even though it has been found to be among the safest and cleanest forms of energy ever developed. That does not appear to be common knowledge among women yet.
Valerie Gardner, Nucleation Capital's managing partner, is working to help set the record straight. She is co-hosting a luncheon gathering for an intimate gathering of women in Los Angeles to discuss nuclear power and share what she has learned over the past 15 years of research and investigation, to dispell myths that still infuse women's thinking about nuclear energy.
Official Event Description
Nuclear for Climate
Join a small group of women gathering at an LA restaurant to enjoy a hosted lunch and discussion exploring the proposition that nuclear power could be exactly what we need to meet the surging demand for energy and solve climate climate safely, sustainably and cost-effectively.
As data centers, cloud computing, vehicle electrification, crypto mining, manufacturing and more create unprecedented demand, energy buyers and the broader utility sector in general are facing a pivotal moment. Will we meet this demand with more cheap but often volatile fossil fuel power generation and continue to make our climate crisis worse? Or will we push forward and accelerate the commercialization of revolutionary advanced nuclear technologies that are clean, dense, low-impact, reliable and climate resilient—everything we need! What if next-generation nuclear is able to compete on every level with fossil fuels, including price? This could change our planet's trajectory for the better, reduce emissions, lessen the threat from climate change and help save our children's future.

An important conversation hosted by Doon Insights
Doon Insights, an investment-focused group organized by Howard Chao, convened dozens of subject-matter experts as speakers (see the list below) across many disciplines in Santa Cruz, California to address trends and issues impacting demand for and supply of energy in the coming years and decades. Energy, which is what makes today's technologically-dependent society possible, is a very large and important topic and was a lot to cover. But in an ambitious, rapid-paced one-day conference titled "POWER SURGE: Solving for Unprecedented Energy Demand," dozens of people laid out the fundamentals and discussed the key questions around both what is driving demand and how will we meet that demand. Questions tackled included:
Demand Side
- Why projections for US power needs now greatly exceed what would have been predicted only a couple of year ago
- Why the exceptional needs of AI Data Centers and the electrification of diverse parts of the economy are driving energy demand
- What are the challenges of building, financing and operating new data centers?
- How much more power will these new facilities require? Where will they be located and what is the attitude of utilities, state and federal government towards supporting them?
- How will the rapidly changing AI competitive landscape affect these power projections? Does the advent of very cheap, highly efficient, smaller SLMs, open source models and Chinese competitors mean that investors have overestimated the need for huge data centers?
- How will the electrification of vehicles, buildings, industry and transactions (blockchain and cryptocurrencies) further accelerate and add significant incremental power demand?
- What are the primary challenges to meeting these power demands of these expanding use cases in the coming years and what will be the main challenges to implementation, including the need to expand the transmission capabilities of the grid?
- Will the new administration's renewed emphasis on fossil fuels result in a slowdown in electrification?
- What will be the impact of the tariffs on the buildout of all these projects?
- How will the new administration's energy policies impact all of these areas? Will we be able to unleash power generation sufficient to sustain the foreseeable economic growth while also continuing to reduce carbon emissions?
Supply Side
- What are the near and longer-term challenges and solutions to the surge in power demand?
- Will growing renewables and batteries be sufficient?
- Will fossil fuels experience a resurgence, with all that drilling?
- Will the sexiest and biggest solutions—nuclear fission and fusion—be coming on stream faster than most people believe?
- What are the short, medium and long-term prospects for these new technologies?
- Will the "privatization" of nuclear innovation and the prevalence of an industry being led by fast-moving private companies, pleasantly surprise us with their speed to market?
- What will be the near-term and longer-term mix of energy solutions?
- How will a patchwork of revamped legacy technologies, including fuel cells, wind, solar, distributed generation, energy storage, energy time-of-use shifting and other behind-the-meter solutions help in the short-term?
- How are advancements in small modular nuclear reactors (SMRs), which offer enhanced safety features, reduced construction times, and the flexibility to be deployed in diverse locations, going to contribute?
- Given that major technology companies like Google and Amazon are investing in SMRs to power their expansive data centers, how will this accelerate commercialization?
- Fusion energy—which is experiencing a wave of breakthroughs, with multiple companies and research initiatives racing to develop and commercialize multiple technologies, such as high-temperature superconductors, improved plasma confinement techniques, and novel neutron flux applications—is beginning to generate revenues but has yet to complete a power-generating reactor design. Will the new administration help accelerate progress towards practical fusion power with pilot plants within the decade or is this game-changing technology still decades away?
The Nuclear Option
Valerie Gardner, Nucleation's managing partner, moderated the day's fission panel, called "The Nuclear Option: Generation IV and Small Modular Reactors," which looked at the role of fission innovation and the coming wave of small, modular reactors (SMRs), that were poised to bring nuclear power into the 21st century. She and her panelists, Leah Crider from Westinghouse (seated on the left), representing the eVinci design, and Clayton Scott from NuScale Power (in the center), which has the first NRC-certified advanced fission design, discussed how and why next-generation nuclear will be the ideal clean energy solution that few think is possible.
While the Fission panel had a full 45 minutes (and probably went over-time) to cover a lot of ground, including reviewing nuclear's status as a major source of today's clean energy, the fact that nuclear is turning into a "technology" product that can be manufactured in factories and shipped to locations, and how a growing assortment of energy buyers like Google, Amazon and Dow Chemical see advanced nuclear as solving their energy needs better than other solutions, because the subject matter was so expansive, Valerie and her panel were able to cover many but definitely not all of the important points. Nevertheless, the fact that this conference's supply-side conversation included nuclear fission at all was a huge victory. This inclusion reflects the fact that nuclear energy is no longer seen as the taboo topic it was long deemed to be, at least up until the last couple of years. For too long, nuclear fission was excluded and no one considered it a vital part of the clean energy solution set. But times have changed and especially among investors looking to understand key long-term trends and be able to invest into them at an early stage.
According to Howard Chao, each panel of the conference, by design, was too short, leaving a lot of unfinished conversations. Nucleation Capital was honored to have been included in this discussion and we look forward to continuing to see interest in advanced nuclear broaden.

Technology companies compete with each other in a lot of ways but they all want to achieve the goal of being able to run operations and data centers using 24/7 carbon-free energy. They've done about as much as they can trying to buy, build and/or get credits from wind and solar plants and it hasn't been sufficient. With its announcement, Google acknowledges that they "need a broader portfolio of advanced clean electricity technologies" to be able to fully decarbonize their energy consumption.
The announcement lists the following as "advanced clean electricity technologies": next-generation geothermal, advanced nuclear, clean hydrogen and long-duration energy storage. This is an astounding announcement because it makes it clear that the tech companies are now moving their focus away from wind and solar, which are just too inconsistent and unreliable, to better, more reliable options.
The initiative aims to aggregate their demand for better types of clean energy to increase their buying power, their lobby power (we have to believe) and diversify the risks of investing in first-of-a-kind (FOAK) plants, whose costs are always higher than "Nth" of a kind plants. They recognize that there are a bevy of developers looking to build next-generation nuclear (and probably also geothermal) plants and they want to be able to help these ventures build those FOAK units, without each individually and solely having to take on risk. This is a tremendously important initiative and concept, it will definitely help accelerate the timelines for companies seeking to get plants built.
THe announcement comes just a few weeks after Amazon announced their purchase of Talen's nuclear-power Cumulous Data Center, which will enable Amazon Web Services to achieve their very ambitious decarbonization goal by 2025. But there aren't many nuclear power plants with spare generating capacity. In order to get access to sufficient quantities of 24/7 clean nuclear power, the U.S. will need to start building next-generation plants, many of which will be Gen IV designs.

Amazon has leapt out ahead of other large tech companies in meeting its 2025 carbon reduction goals by buying Talen's existing nuclear-powered data center, adjacent to and powered by Talen's Susquehanna Nuclear Power Plant. This, however, is part of a trend in which tech companies are going nuclear . . . in order to obtain 24x7 clean energy.
According to Nuclear Newswire, Talen Energy announced the sale of Cumulus Data Assets, its 960-megawatt data center campus to cloud service provider Amazon Web Services (AWS), a subsidiary of Amazon, for $650 million. Cumulus sits on a 1,200-acre campus in Pennsylvania and is directly powered by the adjacent Susquehanna Steam Electric Station, which generates 2.5 gigawatts of power.
“We believe this is a transformative transaction with long term benefits,” said Mark “Mac” McFarland, Talen president and chief executive officer of Talen, on a Monday call with investors and media. As power demand continues to rise worldwide, “data centers are at the heart of that growth,” he added.
“Several years ago, Amazon set an ambitious goal to reach net-zero carbon by 2040—ten years ahead of the Paris Agreement. As part of that goal, we’re on a path to power our operations with 100 percent renewable energy by 2025—five years ahead of our original 2030 target,” an Amazon spokesperson said. “To supplement our wind and solar energy projects, which depend on weather conditions to generate energy, we’re also exploring new innovations and technologies and investing in other sources of clean, carbon-free energy. This agreement with Talen Energy for carbon-free energy is one project in that effort.”
The Susquehanna nuclear power plant is the sixth largest nuclear power plant in the United States and produces 63 million kilowatt hours per day. Its two General Electric boiling water reactors have been on line since 1983 and are licensed to operate through 2042 and 2044, respectively. Talen, its majority owner, is a Houston, Texas-based company, which filed for Chapter 11 bankruptcy in May 2022 as part of a financial restructuring. The company exited bankruptcy in 2023, and officials have said that this recent transaction with AWS is a boost to its cash flow. After paying off debts, interest and other costs, Talen expects net proceeds of $361 million from the deal with Amazon.

This fabulous image shows an electron beam welding metal, a demonstration of new technology developed by Sheffield Forgemasters, a British steelmaker. This innovation will contribute to a new generation of advanced reactors that are smaller, more cost-effective and which can be produced at scale, in part because welding times will go from multiple months to a few hours.
Sheffield's new technology is geared for faster and better fabrication of the pressure vessels that hold the nuclear fuel and where the nuclear reaction takes place. These thick steel containers provide the first level barrier of containment for the nuclear process and radioactive fuel materials and transuranics. Traditionally, creating such vessels required a time-consuming and expensive forging and welding process.
Sheffield Forgemasters' innovative local electron beam welding technique dramatically improves both the process and the quality of the weld by utilizing a particle gun to shoot a very precise beam of high-energy electrons that joins materials at the atomic level without needing to add material, resulting in a faster, stronger and more perfect welds in vessels up to 8 inches thick, that may not even require inspections. This can greatly reduce both the cost and time that it takes to fabricate nuclear pressure vessels while simultaneously producing vessels that are more reliable and longer-lasting.
Sheffield isn't the only group that has been working to improve nuclear technology and capabilities. There are probably hundreds of groups around the world working on the myriad aspects of the nuclear energy industry's challenges, improving communications and even educating the broader community. Nuclear power is just starting to benefit from the advancements provided by the digital age, starting with far more powerful software capabilities that can help with design, testing, modeling, analyses, rendering and reporting. In the future, virtual twinning, remote monitoring, and the use of artificial intelligence, such as that being developed by NuclearN to optimize operations, update procedures, reduce risks through predictive maintenance, conduct AI-based training and many other operations, will increase capabilities and reduce costs both for designing new reactors and for their long-term operations.
Additionally, even as the Congress is working to better rationalize nuclear regulation and reduce its costs by passing a reconciled version of the Senate's bipartisan ADVANCE Act with the version passed by the House, the Atomic Energy Advancement Act, developers are already looking at deploying and utilizing a plethora of advanced capabilities to accelerate development times and reduce build and operational costs. These include:
- Utilizing nano technolologies, miniaturization, automation, and robotics in manufacturing and handling radioactive materials.
- Using 3-D printing and other advanced fabrication technologies to enable rapid design iteration, fast fabrication of unique components
- Deploying advanced materials that improve performance while reducing size, weight, production steps and/or production costs
- Use of more sophisticated test equipment and faster data analysis
- Leveraging technological improvements developed by other industries, such as how Deep Isolation utilizes geologic analysis, horizontal drilling, borehole stabilization and capping technologies developed by the oil and gas industry
- Improving community engagement processes to design and deliver more thoughtful, inclusive, socially just and hence successful engagement processes that build trust and two-way communication.
Nucleation Capital believes that the pressure to decarbonize energy presents one of the largest economic opportunities humanity has ever seen. Nucleation will also invest in a wide range of these vertical supply and support ventures, such as NuclearN and Deep Isolation.
