Powering Heavy Industry & Manufacturing with Advanced Nuclear Energy

Manufacturing is the backbone of the American economy, driving innovation, creating jobs, and ensuring our national security. To make the products we use every day, industries such as chemicals, oil refining, steel, cement, and mining require immense amounts of continuous, high-temperature heat and steam to power operations and industrial equipment. Small Modular Reactors (SMRs) like X-energy’s Xe-100, are able to provide this heat and steam in abundance, offering a reliable, clean energy solution that ensures industrial operations can run 24/7 without disruption.

Why Manufacturing Can Adopt New Energy Technologies

Production lines require constant, high-temperature heat and steam, and nuclear is the sole clean generation source capable of providing it at scale. X-energy’s Xe-100 High-Temperature Gas-cooled Reactor (HTGR) is designed to deliver 565°C steam for industrial applications, making it an ideal power source for heavy industry. The Xe-100 operates continuously, ensuring that manufacturers remain competitive, productive, and energy independent.

HTGRs and the Promise of X-energy’s Xe-100 for Manufacturing

Unlike conventional water-cooled nuclear reactors, HTGRs are designed to deliver high outlet temperatures, often above 500°C (in the case of X-energy’s Xe-100, up to 565°C steam). The Xe-100 reactor can produce up to 80 megawatts of electric power (MWe) and/or up to 200 megawatts of high-temperature thermal output (MWt), depending on the customer’s needs. This high-temperature output produces the steam required for industrial processes, offering a clean and reliable alternative to conventional generating sources.

Key features of the Xe-100 include:

  • Safety-First Design: It uses TRISO-X fuel, a proprietary version of tri-structural isotropic (TRISO) coated particles designed to withstand extreme temperatures.

  • Multi-unit Reliability: The Xe-100can rapidly ramp its power levels up or down, helping industries adapt to fluctuating demands or integrate with intermittent renewables.

  • Modular Scalability: Each reactor module can be built in a controlled factory setting and shipped to the deployment site, reducing construction time and assembly common to large-scale conventional reactors.

High-Temperature Heat for Industrial Processes

One of the most compelling advantages of HTGRs for heavy industry is their capacity to supply high-temperature steam and heat.. This continuous, carbon-free supply of thermal energy can be integrated into processes like:

  • Petroleum Refining & Petrochemicals: Refineries require large volumes of superheated steam for distillation and chemical reactions. HTGRs can provide combined heat and power with zero emissions.

  • Steelmaking: Traditionally reliant on coal or natural gas for heat and reducing agents, steel production can also utilize advanced nuclear for both heat and electrical generation..

  • Mining & Mineral Processing: Operations in remote areas often use diesel generators for heat and power. A compact SMR or microreactor could cut emissions and logistical challenges by running on long-lasting nuclear fuel rather than a constant diesel supply.

Seadrift: A Real-World Example of Industrial Applications

A prime example of advanced nuclear potential in heavy industry is unfolding through Dow’s Seadrift site in Texas. X-energy and Dow have partnered to deploy four Xe-100 SMRs at this large chemical manufacturing facility on the U.S. Gulf Coast, the first advanced nuclear deploymentat an industrial site in North America.

  • Paving the way to Progress: Dow and X-energy have collaborated closely since first announcing their partnership in 2021, and continue to make progress towards the deployment, recently submitting a Construction Permit Application to the U.S. Nuclear Regulatory Commssion..

  • Sustainable Industrial Growth: This project would demonstrate how advanced nuclear reactors can support major industrial operations without compromising output or reliability.

  • A Blueprint for Others: Manufacturers worldwide could replicate this model, reducing emissions with cutting-edge technology while accelerating global momentum for next-generation nuclear technologies.

For more on this milestone project, see “A Year of Progress at Seadrift” on X-energy’s blog.

Repurposing Coal Facilities to Keep U.S. Manufacturing Competitive

Another advantage of smaller, intrinsically safe reactors is the possibility of repurposing former coal plant sites. These sites already have grid connections, water permits, and an experienced energy workforce.

According to estimates by the U.S. Department of Energy, reusing coal infrastructure can save 15–35% in construction costs. This reduces costs for new nuclear facilities and supports communities by keeping or creating local jobs in advanced manufacturing and plant operations.

Modernizing Manufacturing Without Compromising Output

As heavy industry grapples with how to reduce emissions and maintain the continuous, high-quality heat and power essential for production, advanced nuclear power has emerged as an attractive solution.  

High-Temperature Gas-cooled Reactors (HTGRs) like the Xe-100 offer a safe, modular, and carbon-free energy source that can scale to meet large industrial loads. From supporting hydrogen production to repurposing retiring coal sites, advanced nuclear presents a unique opportunity to enhance and expand clean manufacturing for the future.

By integrating next-generation nuclear into their long-term manufacturing strategies, industry can balance the opportunity to reduce emissions with the practical requirements of maintaining continuous operations and product output. Advanced nuclear power isn’t just for electricity; it’s the high-temperature, 24/7 steam and power solution that heavy industry has been waiting for.

Important Questions

1. How do small modular reactors (SMRs) differ from traditional large reactors?
SMRs, like X-energy’s Xe-100, are smaller in size and output, typically between 50 and 300 MWe per module, allowing for modular construction and easier financing. They can be built in factories and shipped to sites in segments, helping reduce both costs and construction timelines.

2. Why is high-temperature heat so important for heavy industry?
Many industrial processes (e.g., chemical manufacturing, steelmaking, refining) need reliable steam supplies at very high temperatures. Traditionally, this heat comes from burning fossil fuels. Advanced nuclear reactors can deliver the same level of heat with zero emissions.

3. Is advanced nuclear power safe?
Yes. Advanced nuclear reactors incorporate numerous intrinsic safety features. X-energy’s Xe-100, for instance, uses TRISO-X fuel, which is designed not to melt even under extreme conditions. The physics-driven safety design ensures the reactor naturally slows down or shuts off if cooling is lost.

4. Can advanced nuclear reactors replace coal-fired plants?
Yes. One major advantage of smaller reactors is that they can often be sited at existing coal facilities, reusing infrastructure and saving 15–35% in construction costs (according to U.S. Department of Energy estimates). This helps local communities adopt clean energy technologies while preserving jobs.

5. How does nuclear power help with hydrogen production?
Hydrogen is already a major commodity in manufacturing, fertilizer production, chemical production, and oil refining, and it will play a major role in decarbonizing sectors such as transportation, manufacturing, and commercial shipping. Hydrogen is currently reliant on fossil fuels for production. Advanced reactors like the Xe-100 supply can provide the necessary energy to power electrolyzers and produce hydrogen without creating carbon emission.

6. Aren’t nuclear plants expensive?
While large, conventional nuclear plants have historically been capital-intensive, SMRs aim to reduce costs and construction timelines through modular designs and factory assembly. Tax credits and government incentives in the U.S. and other countries further improve the economic case for advanced nuclear.

7. Does advanced nuclear create a lot of waste?
All nuclear technology produces some level of spent fuel, but modern reactor designs like the Xe-100 are more fuel-efficient, generating less waste per unit of energy. The durable TRISO-X particles also simplify handling and reduce the possibility of radiation release.

8. Where can I learn more about X-energy’s technology?
Visit X-energy’s official website to explore details about the Xe-100 reactor, TRISO-X fuel, and related initiatives. You’ll find resources on safety, performance, and the company’s vision for a carbon-free future in power and heavy industry.

9. Who is Building SMRs?
X-energy is leading the development of Small Modular Reactors (SMRs) with the Xe-100 high-temperature gas-cooled reactor. Designed for safety, efficiency, and scalability, the Xe-100 uses our proprietary TRISO-X fuel, making it one of the most reliable and advanced SMRs available.

A Year of Progress at Seadrift

One year ago this month, X-energy and Dow announced the selection of Dow's Seadrift, Texas, manufacturing facility as the site for our first Xe-100 advanced small modular reactor plant -- focusing on providing Dow's site with safe, reliable, zero-greenhouse gas emissions power and steam. 

As we reflect on the past year, it's evident that our partnership with the power and manufacturing industry is propelling nuclear energy forward and bringing global attention to the versatility and scalability of advanced nuclear.

Selecting Seadrift

Dow joined X-energy in the U.S. Department of Energy's Advanced Reactor Demonstration Program in March 2023, and the companies signed a joint development agreement to demonstrate the first grid-scale advanced nuclear reactor for an industrial site in North America. In May 2023, Dow announced the selection of its Seadrift site as the project's home.

Spanning 4,700 acres, Seadrift is Dow's second-largest site in Texas and an important manufacturing site for current and future products. With the site's existing energy and steam production assets nearing their end of life, Dow sought to strengthen Seadrift's long-term viability with X-energy's safe, reliable, zero-greenhouse gas emissions technology.

A significant contributor to the local economy, Seadrift employs over 1,200 people and produces more than 4 billion pounds of materials annually. Products manufactured at the site are used across a wide variety of applications including food packaging and preservation, footwear, wire and cable insulation, solar cell membranes, and packaging for medical, pharmaceutical products, and many more essential applications. 

When the Xe-100 plant reaches full operation, it is projected to make a substantial impact, reducing the site's emissions by 440,000 metric tons of CO2e per year. This achievement not only strengthens the site's long-term viability but also serves as a beacon for industries worldwide, demonstrating the potential for significant emissions reduction.

Progress Onsite 

Since site selection, X-energy and Dow have initiated extensive environmental, geological, and geotechnical work to advance progress toward submitting a Construction Permit Application to the U.S. Nuclear Regulatory Commission (NRC) for review and approval. Most of the work onsite includes detailed analysis and testing of the site environment, soil, and water to help ensure that the Xe-100 plant is designed and constructed based on the site's unique characteristics.

To date, crews have drilled nearly 80% of the wells and boreholes required to collect environmental samples. While initially used to inform the completion of a Construction Permit Application (CPA), some of the wells will also support ongoing sampling and monitoring for the expected 60-year life of the plant.

Momentum through Engagement

Following the site announcement, Dow and X-energy leadership hosted a community town hall with neighbors and Seadrift-area stakeholders to provide more details on the project and the expected timeline. In August, the project was the subject of a fireside chat with Texas Governor Greg Abbott, Dow CEO and Chair Jim Fitterling, and X-energy CEO J. Clay Sell. Underscoring the opportunity for energy leadership, Governor Abbott announced the formation of a working group to identify and attract other opportunities to strengthen the state's position in advanced nuclear energy.

A pre-application readiness assessment was initiated with the NRC last October to preview and gather feedback on the project’s draft preliminary safety analysis report (PSAR). The process allows the Commission to provide feedback on most of the nuclear safety portions of the application before its formal submission. The NRC concluded its initial assessment in January 2024, finding no barriers to moving forward and setting a path forward for the submission of the CPA.

The NRC also began its public engagement process earlier this year with a site tour and hosting an open meeting with the community to describe how the application review will unfold.  

Looking Ahead

Looking ahead, our vision extends beyond the construction of the Xe-100 plant. We are committed to fostering a sustainable energy ecosystem that aligns with America's clean energy goals and positions the country as a global leader in next-generation nuclear technology. The upcoming submission of our CPA is a significant step in this journey, marking our progress toward realizing the promise of advanced nuclear power.

The first anniversary of the Dow-X energy collaboration is not merely a milestone but a testament to the power of collaboration and shared vision. We are deeply grateful to all our stakeholders, including the communities near and around Seadrift, for their unwavering support and trust. Your belief in our mission has been instrumental in our progress, and we look forward to continuing this journey together.

Stay tuned as we continue to make strides in transforming the energy landscape. For more information, please visit the Seadrift project page

Fireside Chat: Advancing Nuclear Technology in Texas

Clean, safe, reliable, and capable of powering everything from the grid to heavy industry, X-energy's advanced nuclear technologies are well poised to become a leading player in the global energy market. And as businesses and governments around the world push towards reducing emissions, leaders in both sectors are taking note and growing to appreciate the technology’s full potential.   

Today, X-energy CEO Clay Sell joined Texas Gov. Greg Abbott and Dow CEO Jim Fitterling at the University of Texas at Austin to discuss this growing potential and their shared vision for advanced nuclear in the state.

“It is with tremendous pride that we bring this innovative technology to only a short drive from the energy capital of the world to the state of Texas. I do believe the technology that we will demonstrate here will be the first of many hundreds of plants that are built not just in Texas, around the United States around the world. What is happening here in Texas really will change the world,” Sell said. 

Texas is widely recognized as a leading source of traditional energy solutions – providing more power than any other state, and more than 10% of the net electricity generated in the country.  The state is also on the cutting-edge of innovative, zero-carbon solutions. In fact, Texas is the largest producer of renewable energy in the country, making it the perfect location for X-energy’s advanced small modular reactor (SMR) nuclear project.  

Announced in May of this year, this partnership between X-energy and Dow will deliver a first-of-its-kind four-unit Xe-100 plant at Dow’s Seadrift, Texas facility. The project will provide Seadrift with safe, reliable zero-carbon power and steam production, cutting the site’s emissions by approximately 440,000 MT CO2e/year. Funded in part by the Department of Energy’s ARDP program, construction will begin in 2026 and will conclude by the end of the decade.

X-energy is making great strides in turning advanced nuclear power into the default technology for global, zero-carbon emissions energy. This partnership with Dow will showcase the unique versatility and wide range of applications of the Xe-100 advanced small modular nuclear reactors for energy production and manufacturing and serve as a model for decarbonizing industry around the world.

Gov. Abbott said, “This is the type of scenario where we can have big universities like UT and our other outstanding universities in Texas, work in collaboration with these two incredible private sector leaders. This is what Texas stands for. Texas is the leading innovation state in the United States because we got innovators like X energy and what they're doing, and then we put wind at their back. So this is a perfect example of how Texas brings all these folks together.”


“It's my view that based on this incredible technology that we will first bring to the marketplace with Dow in Texas that we this technology will change the way the world thinks about clean, firm dispatchable power that will provide the reliability that the grid needs and the sustainability that customers are demanding from their energy providers.”

  • J. Clay Sell, CEO, X-energy

"We need 24/7 reliable power. Power needs to be sustainable, reliable, and affordable. And that's where we think new nuclear fits. This is an inherently safer technology than what you're used to seeing. In the utility sector, nuclear is based on light water reactors and you're thinking about large one gigawatt units. One module of the X-energy X-e100 is an 80-megawatt module that generates enough power and steam for us."

X-energy Engages with the International Atomic Energy Agency to Integrate International Safeguards into Xe-100 Design

Safeguards by Design for the Xe-100 is a task under the Canadian Safeguards Support Program

X-energy is proactively engaged in Safeguards by Design (SBD) planning with the International Atomic Energy Agency (IAEA).

Representatives from X-energy visited the IAEA offices in Vienna, Austria, last month to meet with members of the Department of Safeguards through the Member State Support Program (MSSP). The Canadian Nuclear Safety Commission (CNSC) is facilitating the engagement between X-energy and the IAEA as part of the Canadian Safeguards Support Program (CSSP) task on safeguards-by-design for small modular reactors.

“These important meetings allow for an open exchange of information with the IAEA to enhance X-energy’s awareness of safeguard needs and obligations in support of international deployments of the Xe-100,” said Dr. Martin van Staden, X-energy’s senior vice president for the Xe-100, a high temperature gas-cooled reactor developed through decades of research, development, and operating experience.

“We are grateful for the opportunity to work with the IAEA and CNSC to review international safeguards for our Xe-100 reactor design. We are leading the deployment of next-generation nuclear on a global stage by committing to develop solutions that meet international safeguards. This is a voluntary undertaking that demonstrates our commitment to ensuring that the Xe-100 is designed to easily implement international safeguards.”

IAEA safeguards are a series of independent measures coordinated between countries, such as Canada and the IAEA, which verify compliance with the Nuclear Non-Proliferation Treaty (NPT). X-energy is working on safeguard requirements in advance of final design and construction to de-risk international deployment of this advanced nuclear technology. We are building safeguards into the system, rather than around it afterwards. This results in a number of potential advantages, including:

  • Reduced burden on operators, and the IAEA, by optimizing inspections;

  • Enhanced use of advanced technologies, such as unattended monitoring systems and remote data transmission;

  • Reduced risk of costly retrofitting in support of international deployments;

  • Joint use of equipment;

  • Increased flexibility for future installation of safeguards equipment; and

  • Reduced risk to cost, scope and schedule.

“By working with the IAEA at an early stage in reactor design, safeguards considerations can be embedded into the design of these reactors, so that nuclear verification can be performed in the most effective and efficient way with minimal burden on the operator,” said Jeremy Whitlock, Senior Technical Advisor at the IAEA Department of Safeguards, in a 2021 article on the IAEA’s website.

X-energy’s Xe-100 high-temperature gas-cooled reactor (“HTGR”) technology can power a broad range of applications through its high-temperature heat and steam output that can be integrated into and address the needs of large regional electricity providers as well as industrial manufacturing systems. Each module can provide 80 megawatts of full-time electricity. X-energy’s innovative and simplified modular design is road-shippable and intended to drive scalability, accelerate construction timelines and create more predictable and manageable construction costs.

The Advantages of Nuclear Energy

With the ability to deliver safe, reliable energy with zero carbon emissions, nuclear energy is increasingly seen as a solution for drastically reducing our greenhouse gas footprint and mitigating global warming. 

From the general public to governments throughout the world, the nuclear energy advantages are becoming more apparent in the transition to clean, high output energy. 

The primary advantages of nuclear energy include:

  1. Clean

  2. Safe

  3. Reliable

  4. Affordable

Overview of Nuclear Energy and How It Works

Nuclear energy is a clean and efficient way to produce energy and generate electricity without producing greenhouse gas emissions.

Fuel made of uranium is placed in a reactor and generates heat through nuclear fission. This heat is then used to create steam, which can be used for high-temperature industrial processes or to power turbines to generate electricity.

Nuclear energy remains a significant player in the global energy market, with improvements  to ensure its safety, particularly through the use of advanced nuclear technology.

The Benefits of Nuclear Energy

1. Clean

Climate change is one of the biggest challenges facing our world today, which has escalated the need for a clean energy transition.

One option that is increasingly gaining traction is nuclear energy, is a viable energy source and has the potential to play a critical role in mitigating global greenhouse gas emissions.

Advanced nuclear energy is an environmentally friendly option given its ability to conserve water. Unlike conventional power plants, advanced nuclear power plants like the Xe-100 use far less water since they do not need additional water to cool the reactor.

This is beneficial in areas that are prone to droughts or water scarcity, relieving the pressure on water supplies.

Moreover, nuclear power plants contribute to significantly less air pollution. They don't produce the emissions that are hazardous to both human health and the environment.

2. Safe

Nuclear power plants are subject to some of the most stringent safety regulations of any industrial sector. These regulations cover every aspect of plant operation, from design and construction to maintenance and decommissioning.

In addition, advanced nuclear power facilities are equipped with state-of-the-art safety technologies meant to prevent accidents and minimize their impact if they occur. 

These safety measures include emergency cooling systems, backup power sources, and other safeguards designed to protect both the nuclear reactor and the surrounding area in the event of an accident.

Advanced SMRs also have lower reactor power density and a self-regulating core design. This means that the core is designed to shut down if cooling stops and is intended to prevent the reactor from melting under foreseeable adverse conditions without action by the operator. 

Because of this, the emergency planning zone for advanced SMRs can be at the site boundary, allowing the technology to be located closer to population centers and industrial facilities that require process heat. 

Safety is also a top priority in the nuclear industry, and ongoing research and development are focused on improving safety even further. This includes research into new reactor designs, safety systems, and accident mitigation strategies.

3. Reliable

While renewable energy sources such as wind and solar have increased and will continue to become a greater share of the global energy supply, they are constrained by their inability to provide consistent base-load electricity power due to their intermittency.

Advanced small modular reactors, on the other hand, have load-following capabilities and are designed to ramp up or ramp down based on customer needs.

Nuclear energy is one of the most reliable and consistent sources of energy, as stated by the United States Department of Energy.

Rising energy consumption and the increased focus on decarbonization create a significant requirement for nuclear energy's carbon-free, always-on generation.

Nuclear power facilities can run continuously for long periods of time without needing frequent maintenance or refueling.

As a result, they can consistently supply electrical grids with uninterruptible electricity. Because of this, grid managers can plan and manage the supply of electricity more effectively.

4. Affordable

Nuclear energy is a cost-effective alternative to traditional sources of power and offers a reliable source of electricity.

Advanced small modular reactors are largely factory built and road-shippable, which reduces on-site work and results in better cost predictability and more efficient quality control.

Conventional large-scale nuclear facilities, however, have high upfront capital costs due to their large size, substantial containment structures, and longer construction times. 

The cost of nuclear fuel, which is primarily based on uranium, is also relatively low compared to other fossil fuels and natural gas. This means that the cost of fuel makes up a relatively small portion of the total cost of generating electricity at a nuclear power plant.

Nuclear power plants also have operational lifetimes up to 60 years, resulting in a relatively low cost per kilowatt-hour of electricity produced.

Due to their extended lifespan, the initial cost of establishing a nuclear power station can be distributed over a more extended period, making nuclear energy a cost-effective option.

How Countries are Utilizing Nuclear Energy Technology for Sustainable Development

Several countries, communities, and public bodies have adopted nuclear power as an alternative source of energy and a means to achieve sustainable development. 

In recent years, there has also been significant developments in nuclear technology. One of the most notable advancements has been the use of small modular nuclear reactors, which are mobile and can provide energy to remote areas.

In fact, advanced small modular reactors (SMRs) –  specifically, high temperature gas reactors (HTGRs) like X-energy’s Xe-100 – have several inherent advantages over other carbon-free power generation, including existing Generation III SMR and conventional large-scale technologies.
