The United States took a major step toward the next generation of nuclear energy after the U.S. Nuclear Regulatory Commission approved a construction permit for TerraPower’s first Natrium reactor.
The permit allows the company to begin building Kemmerer Unit 1, a commercial-scale advanced nuclear power plant in Wyoming. Notably, this is the first advanced reactor project in the U.S. to receive such approval, marking an important milestone for the future of clean energy and nuclear innovation.
Developed by TerraPower in partnership with GE Vernova Hitachi Nuclear Energy, the Natrium system combines a 345-megawatt sodium-cooled fast reactor with a molten salt energy storage system. The project is also supported through the U.S. Department of Energy Advanced Reactor Demonstration Program.
With regulatory approval secured, TerraPower plans to begin construction within weeks and aims to complete the plant by 2030.
A Long Regulatory Journey Reaches a Breakthrough
Securing approval for a new nuclear design is a rigorous and lengthy process. TerraPower spent more than four years working closely with regulators to reach this stage.
The company first engaged with the NRC through extensive pre-application consultations. These discussions helped refine the reactor’s design and ensured regulators fully understood the new technology. TerraPower then submitted its official construction permit application in March 2024, and the NRC formally accepted the filing in May 2024.
Initially, the regulator expected the review process to take 27 months. However, the timeline moved faster than anticipated.
Several factors helped accelerate the review:
- TerraPower submitted a comprehensive technical application.
- The company responded quickly to regulator questions.
- NRC staff prioritized the project’s review.
- Federal policies encouraged faster licensing of advanced reactors.
As a result, the approval process finished in 18 months, making it one of the fastest regulatory reviews for a new nuclear technology in the United States.
This milestone positions TerraPower as a first mover in the advanced reactor market, which many experts see as essential for meeting future energy demand while reducing emissions.
Natrium: A New Kind of Nuclear Reactor
Unlike traditional nuclear plants, the Natrium system uses sodium instead of water as its coolant. This design change brings several operational advantages.

Most existing nuclear facilities rely on light water reactors, which operate under high pressure. In contrast, the Natrium reactor runs at low pressure and high temperatures, reaching more than 350°C (662°F) while remaining far below sodium’s boiling point.
Because of this design, the reactor can rely on natural forces such as gravity and thermal convection for cooling. This passive safety approach reduces the need for complex emergency systems and lowers construction costs.
Another key innovation is the plant’s integrated energy storage system.
The reactor continuously produces 345 megawatts of electricity, ensuring stable baseload power. Meanwhile, molten salt storage can hold excess heat and release it later to boost output to 500 megawatts during periods of high demand.
Instead of running at a constant power level like traditional nuclear plants, the system can adjust electricity production based on grid needs. That flexibility allows it to complement renewable energy sources such as wind and solar.
Thus, this capability makes the Natrium plant unique among advanced reactor designs.
In addition, the design separates the nuclear reactor from the energy storage and power generation systems. This “decoupling” means non-nuclear teams can operate components such as steam turbines and salt tanks outside the nuclear island, improving safety while reducing operational costs.
Supporting Decarbonization Beyond Electricity
The Natrium plant is designed to deliver more than just electricity.
Because the reactor produces high-temperature heat, it can also supply industrial steam and thermal energy. This opens opportunities to decarbonize sectors that are traditionally difficult to electrify, including heavy industry and manufacturing.
The technology can therefore support multiple applications:
- Carbon-free electricity generation
- Industrial heat supply
- Steam production for industrial processes
- Grid stability alongside renewables
With an expected operational life of up to 80 years, the Natrium system could provide reliable low-carbon energy for decades.
Nuclear Power’s Role in America’s Energy Strategy
The approval of TerraPower’s Natrium project comes as the United States seeks to significantly expand its nuclear power capacity.
The U.S. already leads the world in nuclear generation, producing roughly 30% of global nuclear electricity. According to the Energy Department, the country has about 100 gigawatts of nuclear capacity today.
However, the government aims to quadruple that capacity to 400 gigawatts by 2050 to meet growing electricity demand and climate targets.
Federal policies are increasingly focused on rebuilding the nuclear supply chain and accelerating the deployment of new reactors.

Recent initiatives include:
-
$2.7 billion investment in uranium enrichment was announced in January 2026 to strengthen the domestic nuclear fuel supply.
-
$800 million in funding for small modular reactors was awarded in December 2025 to support projects led by utilities and developers.
-
A $1 billion loan to restart the Crane Clean Energy Center nuclear plant in Pennsylvania.
These measures reflect a broader push to ensure the United States maintains leadership in advanced nuclear technology.
Several companies are already developing next-generation reactors, including Oklo, Kairos Power, and X-energy. However, many of those projects are expected to deploy in the mid-2030s.
That timeline makes TerraPower’s Natrium project one of the earliest large-scale demonstrations of advanced reactor technology in the United States.
Rising Power Demand From AI and Data Centers
Another factor driving interest in nuclear energy is the rapid growth of data centers and artificial intelligence infrastructure.
Large technology companies, or the hyperscalers, are building massive data centers to support AI systems and cloud computing. These facilities consume enormous amounts of electricity and require reliable, constant power. As demand grows, many tech companies are exploring nuclear energy to secure their own supply rather than relying solely on public grids.
This trend could reshape the energy landscape. Governments must balance the needs of fast-growing digital industries with the need to keep electricity affordable for households and businesses.
The outcome may also influence the global AI competition between the United States and China, where access to reliable power could become a strategic advantage.

Nuclear Generation Remains Strong in the U.S.
Despite maintenance cycles, nuclear power continued to provide stable and high levels of electricity in 2025. According to the Energy Information Administration (EIA), U.S. nuclear generation stayed consistently strong throughout the year. Output typically dipped during scheduled maintenance periods but rebounded quickly afterward.
The year ended on a particularly strong note. December 2025 recorded about 72–73 million megawatt-hours of nuclear generation, one of the highest monthly totals of the year.

This reliability is one reason policymakers continue to support nuclear energy as a key component of the country’s low-carbon power system.
In conclusion, the construction permit for the Natrium plant signals that advanced reactors are moving from concept to reality. And for TerraPower, the next step is clear: begin construction and prove that advanced nuclear technology can deliver reliable, carbon-free power at commercial scale.

How Climate Change Is Raising the Cost of Living
Americans are paying more for insurance, electricity, taxes, and home repairs every year. What many people may not realize is that climate change is already one of the drivers behind those rising costs.
For many households, climate change is no longer just an environmental issue. It is becoming a cost-of-living issue. While climate impacts like melting glaciers and shrinking polar ice can feel distant from everyday life, the financial effects are already showing up in monthly budgets across the country.
Today, a larger share of household income is consumed by fixed costs such as housing, insurance, utilities, and healthcare. (3) Climate change and climate inaction are adding pressure to many of those expenses through higher disaster recovery costs, rising energy demand, infrastructure repairs, and increased insurance risk.
The goal of this article is to help connect climate change to the everyday financial realities people already experience. Regardless of where someone stands on climate policy, it is important to recognize that climate change is already increasing costs for households, businesses, and taxpayers across the United States.
More conservative estimates indicate that the average household has experienced an increase of about $400 per year from observed climate change, while less conservative estimates suggest an increase of $900.(1) Those in more disaster-prone regions of the country face disproportionate costs, with some households experiencing climate-related costs averaging $1,300 per year.(1) Another study found that climate adaptation costs driven by climate change have already consumed over 3% of personal income in the U.S. since 2015.(9) By the end of the century, housing units could spend an additional $5,600 on adaptation costs.(1)
Whether we realize it or not, Americans are already paying for climate change through higher insurance premiums, energy costs, taxes, and infrastructure repairs. These growing expenses are often referred to as climate adaptation costs.
Without meaningful climate action, these costs are expected to continue rising. Choosing not to invest in climate action is also choosing to spend more on climate adaptation.
Here are a few ways climate change is already increasing the cost of living:
- Higher insurance costs from more frequent and severe storms
- Higher energy use during longer and hotter summers
- Higher electricity rates tied to storm recovery and grid upgrades
- Higher government spending and taxpayer-funded disaster recovery costs
The real debate is not whether climate change costs money. Americans are already paying for it. The question is where we want those costs to go. Should we invest more in climate action to help reduce future climate adaptation costs, or continue paying growing recovery and adaptation expenses in everyday life?
How Climate Change Is Increasing Insurance Costs
There is one industry that closely tracks the financial impact of natural disasters: insurance. Insurance companies are focused on assessing risk, estimating damages, and collecting enough revenue to cover losses and remain financially stable.
Comparing the 20-year periods 1980–1999 and 2000–2019, climate-related disasters increased 83% globally from 3,656 events to 6,681 events. The average time between billion-dollar disasters dropped from 82 days during the 1980s to 16 days during the last 10 years, and in 2025 the average time between disasters fell to just 10 days. (6)
According to the reinsurance firm Munich Re, total economic losses from natural disasters in 2024 exceeded $320 billion globally, nearly 40% higher than the decade-long annual average. Average annual inflation-adjusted costs more than quadrupled from $22.6 billion per year in the 1980s to $102 billion per year in the 2010s. Costs increased further to an average of $153.2 billion annually during 2020–2024, representing another 50% increase over the 2010s. (6)
In the United States, billion-dollar weather and climate disasters have also increased significantly. The average number of billion-dollar disasters per year has grown from roughly three annually during the 1980s to 19 annually over the last decade. In 2023 and 2024, the U.S. recorded 28 and 27 billion-dollar disasters respectively, both setting new records. (6)
The growing impact of climate change is one reason insurance costs continue to rise. “There are two things that drive insurance loss costs, which is the frequency of events and how much they cost,” said Robert Passmore, assistant vice president of personal lines at the Property Casualty Insurers Association of America. “So, as these events become more frequent, that’s definitely going to have an impact.” (8)
After adjusting for inflation, insurance costs have steadily increased over time. From 2000 to 2020, insurance costs consistently grew faster than the Consumer Price Index due to rising rebuilding costs and weather-related losses.(3) Between 2020 and 2023 alone, the average home insurance premium increased from $75 to $360 due to climate change impacts, with disaster-prone regions experiencing especially steep increases.(1) Since 2015, homeowners in some regions affected by more extreme weather have seen home insurance costs increased by nearly 57%.(1) Some insurers have also limited or stopped offering coverage in high-risk areas.(7)
For many families, rising insurance costs are no longer occasional financial burdens. They are becoming recurring monthly expenses tied directly to growing climate risk.
How Rising Temperatures Increase Household Energy Costs

The financial impacts of climate change extend beyond insurance. Rising temperatures are also changing how much energy Americans use and how utilities plan for future electricity demand.
Between 1950 and 2010, per capita electricity use increased 10-fold, though usage has flattened or slightly declined since 2012 due to more efficient appliances and LED lighting. (3) A significant share of increased energy demand comes from cooling needs associated with higher temperatures.
Over the last 20 years, the United States has experienced increasing Cooling Degree Days (CDD) and decreasing Heating Degree Days (HDD). Nearly all counties have become warmer over the past three decades, with some areas experiencing several hundred additional cooling degree days, equivalent to roughly one additional degree of warmth on most days. (1) This trend reflects a warming climate where air conditioning demand is increasing while heating demand generally declines. (4)
As temperatures continue rising, households are expected to spend more on cooling than they save on heating. The U.S. Energy Information Administration (EIA) projects that by 2050, national Heating Degree Days will be 11% lower while Cooling Degree Days will be 28% higher than 2021 levels. Cooling demand is projected to rise 2.5 times faster than heating demand declines. (5)
These projections come from energy and infrastructure experts planning for future electricity demand and grid capacity needs. Utilities and grid operators are already preparing for higher peak summer electricity loads caused by rising temperatures. (5)
Longer and hotter summers also affect how homes and buildings are designed. Buildings constructed for past climate conditions may require upgrades such as larger air conditioning systems, stronger insulation, and improved ventilation to remain comfortable and energy efficient in the future. (10)
For many households, this means higher monthly utility bills and potentially higher long-term home improvement costs as temperatures continue to rise.
How Climate Change Affects Electricity Rates
On an inflation-adjusted basis, average U.S. residential electricity rates are slightly lower today than they were 50 years ago. (2) However, climate-related damage to utility infrastructure is creating new upward pressure on electricity costs.
Electric utilities rely heavily on above-ground poles, wires, transformers, and substations that can be damaged by hurricanes, storms, floods, and wildfires. Repairing and upgrading this infrastructure often requires substantial investment.
As a result, utilities are increasing electricity rates in response to wildfire and hurricane events to fund infrastructure repairs and future mitigation efforts. (1) The average cumulative increase in per-household electricity expenditures due to climate-related price changes is approximately $30. (1)
While this increase may appear modest today, utility costs are expected to rise further as climate-related infrastructure damage becomes more frequent and severe.
How Climate Disasters Increase Government Spending and Taxes
Extreme weather events also damage public infrastructure, including roads, schools, bridges, airports, water systems, and emergency services infrastructure. Recovery and rebuilding costs are often funded through taxpayer dollars at the federal, state, and local levels.
The average annual government cost tied to climate-related disaster recovery is estimated at nearly $142 per household. (1) States that frequently experience hurricanes, wildfires, tornadoes, or flooding can face even higher public recovery costs.
These expenses affect taxpayers whether they personally experience a disaster or not. Climate-related recovery spending can increase pressure on public budgets, emergency management systems, and infrastructure funding nationwide.
Reducing Climate Costs Through Climate Action
While this article focuses on the growing financial costs associated with climate change, the issue is not only about money for many people. It is also about recognizing our environmental impact and taking responsibility for reducing it in order to help preserve a healthy planet for future generations.
While individuals alone cannot solve climate change, collective action can help reduce future climate adaptation costs over time.
For those interested in taking action, there are three important steps:
- Estimate your carbon footprint to better understand the emissions connected to your lifestyle and activities.
- Create a plan to gradually reduce emissions through energy efficiency, cleaner technologies, and more sustainable choices.
- Address remaining emissions by supporting verified carbon reduction projects through carbon credits.
Carbon credits are one of the most cost-effective tools available for climate action because they help fund projects that generate verified emission reductions at scale. Supporting global emission reduction efforts can help reduce the long-term impacts and costs associated with climate change.

Carbon credit project stewardship: what happens after credit issuance
A carbon credit purchase is not a transaction that closes at issuance. The credit may be retired, the certificate filed, and the reporting box ticked. But on the ground, in the forest, in the field, and in the community, the work continues. It endures for years. In many cases, for decades.
