NRC Unlocks Factory Fueling for Microreactors

NRC-memo-jun-2025

In a major policy shift, the U.S. Nuclear Regulatory Commission (NRC) has approved new guidance that allows microreactors to be fueled and tested in factories. This could significantly accelerate deployment timelines for advanced nuclear startups.

Outlined in a June 17 memo, the policy allows:

  • Fuel to be loaded at the factory, as long as the design includes safeguards to prevent criticality;

  • Operational testing to occur prior to shipment;

  • A redefinition of “operation” to begin only when those safeguards are removed post-deployment

This change removes key bottlenecks for companies building modular, transportable systems.

Here’s how it directly supports our portfolio:

Radiant (Q4 2021, Q1 2025): Radiant’s portable nuclear generators stand to benefit from off-site testing and factory fueling, especially for defense and remote energy use cases.

Aalo (Q3 2024, Q4 2024): Aalo’s sealed microreactors are built for factory assembly and shipment. These policies enable validation and fueling pre-deployment, accelerating early commercial pilots.

Blue Energy (Q4 2024): With a focus on modular deployment, Blue can now pursue pre-operational qualification in the factory, reducing on-site regulatory hurdles and shortening the path to demonstration.

These updates reflect a broader shift at the NRC toward enabling next-gen deployment models, aligned with the ADVANCE Act’s mandate for risk-informed, performance-based licensing.

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.

Germany drops its anti-nuclear stance ()

Germany has dropped its long-held opposition to nuclear power, in the first concrete sign of rapprochement with France by Berlin’s new government led by conservative Chancellor Friedrich Merz. Berlin has signalled to Paris it will no longer block French efforts to ensure nuclear power is treated on par with renewable energy in EU legislation, according to French and German officials.
