Nuclear for Climate Change: A luncheon discussion

Luncheon discussion

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.)

Bisconti nuclear surveyNuclear 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.

POWER SURGE: Report on this one-day conference

Power surge conference

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:

The demand side    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?

  • 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

Screenshot 2025 05 04 at 8.23.42 amValerie 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.

Assessing the Election’s Impacts on Nuclear

By Valerie Gardner, Nucleation Capital Managing Partner

Kh v dt.png

Presidential elections are always important and this year's election is widely considered particularly critical and unusual.  There are vast differences of opinion on matters of great national importance—from voting rights and health policies to international relations and national security policies. Less well litigated is where these candidates stand on matters of energy security, the energy transition and future deployments of both traditional and advanced nuclear power. How will the differences in character, knowledge and respect for facts, science and experts play out on U.S. policies towards nuclear power?  Based upon various sources, it appears that the election will have a significant impact. For those still making up their minds, this summary assessment may help clarify how numerous pundits view these differences.

Summary

Nuclear energy has enjoyed enduring bipartisan support across both Democratic and Republican administrations for years now. The Congress has passed, with overwhelming bipartisan majorities, bills aimed at modernizing and accelerating commercialization of new nuclear.

Nevertheless, in 2024, the two presidential candidates bring potentially unconventional approaches that may differ from the standard positions of their respective parties. Republicans have long valued America's nuclear capacity and have seen the need for the US to maintain leadership to boost both national security and to expand our ability to export our technologies. They recognize that the U.S. needs to counter the geopolitical influence of adversaries like Russia and China which are offering to help developing nations with nuclear power as a means of increasing their influence within those countries.

Democrats have also, if more recently, come around to support nuclear. Both the Obama White House and the Biden Administration have provided broad support for the industry and particularly for the acceleration of next-generation nuclear technologies and American leadership in the energy transition. Front and center of their support is the recognition that nuclear power is a critical, differentiated component of a reliable, 24/7 low-carbon energy grid. They support its expansion primarily as a mechanism to meet growing energy needs and fortify grid reliability while reducing carbon emissions and addressing climate change, in tandem with renewables.

The question then of which candidate is more likely to support the continued acceleration of nuclear power is thus wrapped up with policies relating to energy security, fossil fuels, geopolitical competition with Russia and China, and support for addressing climate change. The Inflation Reduction Act passed in 2022 and signed by President Biden marked the Congress' single largest investment in the economy, energy security and climate change and is widely seen as the most important piece of climate legislation ever passed. It simultaneously rebuilds the U.S. industrial capabilities while incentivizing the growth of clean energy technologies including domestic nuclear power. It is already making an enormous and beneficial impact on the U.S. nuclear indsutry.

Kamala Harris, while possibly more progressive than Biden, has shown her support for Biden's approach to incentivizing the clean energy transition through the IRA, Biden's signature piece of climate legislation, which has received staunch support from industry. She is unlikely to make many if any changes to the IRA's clean energy technology-neutral Investment Tax Credits and Production Tax Credits or reduce the billions in loan guarantees available through the Loan Program Office, which have already stimulated significant investment in protecting and restarting existing reactors.

Because of Biden’s Infrastructure Investment & Jobs Act’s Civil Nuclear Credit program, California is proceeding with the relicensing of Diablo Canyon, Holtec has chosen to restart, rather than decommission, Michigan’s Palisades nuclear power plant, Constellation has inked a deal with Microsoft to restart Three Mile Island Unit 2, and NextEra Energy is actively considering the restart of Duane Arnold. Meanwhile, Google has signed a deal to buy power from advanced nuclear reactors being designed by Kairos Power and Amazon has signed a similar deal with X-energy, marking the first corporate purchases of next-generation nuclear, thanks to highly motivating tax and financing incentives available through the IRA and LPO.

Harris is clearly committed to addressing climate change. There is no evidence that she rejects the clean energy tech-agnostic approach developed during her term as Vice President, which levels the playing field for nuclear energy as a clean energy source. Harris recognizes the geopolitical importance of America's ability to compete with Russia to produce our own nuclear fuel supply and to provide nuclear technologies to developing nations seeking to build their clean energy capacity but wanting to remain free of Russian or Chinese influence.

In contrast, Donald Trump has repeatedly called climate change a "hoax," and/or a good thing and cares little about reducing U.S. or global emissions. He previously walked away from the Paris accord and would likely try to repeal, roll back or dilute the IRA. He's publicly allied himself with the fossil fuel industry and—in exchange for donations—has promised to roll back EPA regulations and help them "drill, drill, drill."

There is almost no doubt that Trump would step the U.S. away from its leadership role on climate and this time, that may mean reversing the U.S.'s pledge to triple the amount of nuclear power. This would seriously undermine both the U.S. nuclear industry's momentum to expand to meet growing demand as well as international progress. Given Trump’s overt courting of Putin, he may be disinclined to rebuild the U.S.'s nuclear fuel production capacity or seek to accelerate or support American efforts to build nuclear projects internationally in competition with Russia.

None of this would be good for nuclear power. Any potential efforts to rollback the IRA would slow restoration, development and deployment of reactors. Boosting the fossil fuel industry, whether through supporting expanded access to federal land or price manipulation to improve profitability would have severe impacts on the energy transition. Trump's recent acknowledgement that he didn't believe nuclear was safe also belies the stated "commitment" to nuclear energy expressed by his surrogates and gives considerable fodder to those who persist in opposing nuclear. His shoot-from-the-hip, truth-be-damned leadership style and embrace of conspiracy theorists, contrasts starkly with Harris' stated willingness to consult with scientific experts and even give those who disagree with her a seat at the table.

In sumary, Trump's likely propensity to undermine the IRA, oppose climate action and backtrack on US pledges to triple nuclear, his support for expanding fossil fuel production and his continued disdain for science and technical experts, poses extreme risks to the momentum generated within the nuclear sector over the last few years. Trump's ignorance of nuclear energy's exceptional safety performance make him unlikely to provide Oval Office leadership either to the industry or the NRC in support of the bipartisan ADVANCE Act, signed into law by Biden.

In contrast, a Harris Administration would likely remain on the current climate glideslope for leadership, technology-neutral funding and the U.S.'s nuclear tripling momentum as stimulated by the Biden Administration. It may be that a Harris Administration does not prioritize nuclear's growth or add billions in new accelerants as Biden has done, but she will not try to trash it. Having been briefed by senior energy advisors over the last four years about the importance of nuclear, she is well-informed and understands the importance of Biden's initiatives for addressing climate.

Based on this analysis, those who support an expansion of nuclear power and enduring progress towards transitioning away from fossil fuels should thus prefer to see Harris elected, rather than Trump, and the existing policies continued.

Michael (Marty) Marinak: Computational physicist at LLNL

Marty serves as a computational physicist for the Lawrence Livermore National Lab in the National Ignition Facility group. He  received his Bachelor’s Degree in Nuclear Engineering from U.C. Berkeley. After graduating, Marty was awarded a Berkeley Fellowship for Graduate Study and proceeded to earn a Ph.D. in Nuclear Engineering from the University of California at Berkeley in 1993.

The cutaway view shows density on the right where the capsule shell contains the hot spot. The jet from the fill tube is visible near the equator. Ion temperature is shown on the left. Credit: Marty Marinak.

Dr. Marinak is the lead developer for HYDRA, the principal Inertial Confinement Fusion (ICF) simulation code used today. It is because of that simulation capability—combined with exponential growth in high performance computing (HPC) at LLNL, which allowed for the first high-resolution fully spherical 3D simulations of ICF implosions, as well a breakthroughs in ignition at NIF. The code continues to be fundamental for target designers to “try things out” and provides insights into which designs could be successful, given that there are limited numbers of "shots" from the NIF each year.

In April 2023, the National Ignition Facility published an article "Computing Codes, Simulations Helped Make Ignition Possible," with a few quotes from Marty regarding the work he was doing designing codes and computer simulations that have enabled NIF's quest for ignition. Codes are what provide valuaable information that can be used to analyze data and extrapolate predicted results from implosion symmetry, stability and timing, to better tailor new trials for success.

Now that NIF has achieved ignition, this has validated the success of the HYDRA codes developed which enabled the scientists working with the target fabrication team and the laser teams to view full-sphere simulations, giving them a much clearer understanding of what problems needed to be fixed to make ignition happen. In doing so, HYDRA guided the ICF process to move closer to the target reality and achieve success.

“When we started generating diagnostics from full-sphere 3D simulations, a lot of the mysteries went away,” Marinak said. “The simulations told us if you fixed just one of those issues, you probably wouldn't be able to measure an improvement. Even if you fixed all of them to within target fabrication’s abilities, you still wouldn't get the capsule to ignite. That was the turning point. We couldn’t just fix the sources of asymmetry. We needed a more robust target. . . .

Based on the knowledge gained from HYDRA and other codes, Marinak was confident target design was “moving in the right direction” and would eventually result in higher yields.

“I always thought we would make it, but ignition is difficult and was harder to accomplish than we had thought, and that's probably why there’s no one else in the world that has done it,” Marinak said. “Now we have a much clearer understanding of the behavior of these implosions and the challenges that must be overcome.

“We promised that we could do this thing that no one else has done before for stockpile stewardship and for other purposes, and it was greatly rewarding to finally see that we helped to make that happen.”

Dr. Marinak is the principal author on a number of articles in peer-reviewed scientific journals, and co-author on many more.
