Imagine you’re in a control room, managing a nuclear reactor. Suddenly, an emergency shutdown occurs. This scenario is part of a demonstration at NuScale, a company pioneering the next generation of nuclear power through Small Modular Reactors (SMRs). These reactors could revolutionize the nuclear industry, offering a fresh perspective on energy production.
Nuclear power plants have been a staple of energy production for decades. They work by splitting uranium atoms, a process that generates heat. This heat boils water, producing steam that drives turbines to generate electricity. While effective, this process also creates radioactive materials, necessitating stringent safety measures to prevent environmental contamination.
The nuclear industry has faced significant setbacks, particularly after incidents like Three Mile Island and Fukushima. These events prompted countries like Germany and Switzerland to phase out nuclear power. In the U.S., aging reactors are being retired, and major companies like Westinghouse have faced financial difficulties. The high costs of building and maintaining large nuclear plants, coupled with cheaper alternative energy sources, have made new projects less appealing.
Amid these challenges, SMRs offer a promising solution. These reactors are smaller, producing less than 300 megawatts of electricity compared to the 1,100 megawatts of traditional plants. Their modular design allows for factory production, ensuring high-quality components and efficient construction. This approach could significantly reduce costs and construction times.
NuScale’s SMR design includes a containment vessel housing the reactor and steam generator, all submerged underwater. Up to 12 modules can be added to a single pool, with each module generating about 60 megawatts—enough to power 50,000 homes. The design prioritizes safety, featuring passive safety systems that enable automatic shutdowns without human intervention.
NuScale plans to launch its first commercial plant by 2026, near the Idaho National Laboratory. Their design has been submitted for approval to the U.S. Nuclear Regulatory Commission (NRC), highlighting a smaller emergency planning zone due to enhanced safety features. The reactors are designed to withstand seismic activity and extreme weather, minimizing the risk of radioactive release.
While nuclear power has historically been safe, concerns about waste management and proliferation risks persist. Government funding is crucial for these projects, raising questions about public investment. However, the potential benefits, such as producing clean desalinated water, make SMRs attractive to governments worldwide. Countries like China are also developing SMRs, which could have geopolitical implications.
NuScale’s efforts to innovate the nuclear industry could address many of the challenges that have hindered previous projects. Their safer design and automated systems offer a glimpse into a future where nuclear power is more accessible and sustainable. However, questions about waste management and real-time operation remain. As these models are tested, the true potential of SMRs will become clearer, determining whether smaller reactors are indeed the future of nuclear energy.

Pat, we have a reactor trip on Unit 5. Containment is isolated. The cooling system is isolated. The cooling water system is isolated. The decay heat removal system is in service. A pressurizer heater trip has occurred. All safety functions are operational. Understood. We have a reactor trip on Unit 5, and all safety functions are operational. That’s correct. Ryan, can you take over the plant response to Unit 5? You’re in the middle of a simulated reactor trip. Something happened that’s causing an emergency shutdown. Ryan, I have acknowledged the alarms. Understand that you’ve acknowledged the alarms.
This demonstration took place at NuScale, a next-generation nuclear power company that aims to operate a series of up to 12 small reactors from a single control room. Their new model may help revitalize the nuclear power industry. When you think of nuclear power, you might picture a plant with large cooling towers and steam billowing out. These plants have been part of our energy mix for decades, harnessing the power of splitting uranium atoms. In simple terms, nuclear power is a complex method of boiling water. The goal is to convert the energy produced by splitting uranium nuclei into steam, which then drives a turbine to generate electricity.
The splitting process produces radioactive materials, and much of the nuclear plant’s focus is on ensuring these materials do not escape into the environment. There are hundreds of reactors operating worldwide, and you might live near one. However, the nuclear industry is currently facing significant challenges. The incidents at Three Mile Island and Fukushima led countries like Germany and Switzerland to dismantle their nuclear power infrastructure. Despite efforts from Russia and China to initiate new projects, global construction is currently declining. In the U.S., aging reactors are being retired, and Westinghouse, a major player in the industry, recently filed for bankruptcy.
The nuclear industry’s previous argument was that, despite the high construction costs, nuclear plants are inexpensive to operate and thus profitable. However, this equation has shifted in recent years. As these plants age, operational costs have risen, while the costs of alternative energy sources have decreased significantly. Additionally, the expectation that lessons learned from past mistakes would lead to reduced costs and faster construction has not materialized. The South Carolina project was abandoned after spending about $9 billion, and the Georgia plant’s costs have ballooned to around $25 to $27 billion, far exceeding initial estimates. Consequently, many believe that building another large nuclear plant in the U.S. is not a viable option.
This situation is particularly challenging given rising CO2 emissions and the need for alternatives to meet climate goals. This is where next-generation reactors come into play. These new nuclear systems, known as Small Modular Reactors (SMRs), aim to address the issues of cost and scalability. “Small” refers to their capacity of less than 300 megawatts of electricity, compared to the 1,100 megawatts generated by larger plants. “Modular” means these reactors can be manufactured in a factory, allowing for high-quality components to be produced in parallel while civil construction occurs on-site.
Portable nuclear power has a historical context, having been pursued since the Cold War, with several designs used in nuclear submarines and university labs. After years of attempts, SMRs have yet to become a mainstream power source for local communities, but NuScale aims to change that. The project began with funding from the Department of Energy in 2000, in collaboration with the Idaho National Laboratory, focusing on a factory-built small reactor concept.
NuScale’s modules include a containment vessel that is about 76 feet long and 15 feet in diameter, housing the reactor vessel and steam generator. These components are located underwater and can be scaled by adding up to 12 modules in a single pool. Each module produces about 60 megawatts of electricity, enough to power approximately 50,000 homes. The design emphasizes safety, with passive safety features that allow the reactors to shut down without operator or computer intervention and remain cooled indefinitely without additional water.
In the control room, many functions do not require operator action, as procedures are displayed on screens to assist operators. NuScale’s timeline includes plans to turn on their first commercial plant near the Idaho National Laboratory by 2026. They have submitted a comprehensive design certification application to the U.S. Nuclear Regulatory Commission (NRC), which includes a request for a smaller emergency planning zone due to their high safety standards.
The reactor is designed to be located in a pool below ground, with protective features against seismic activity and extreme weather. Their analysis indicates that they do not exceed regulatory doses under worst-case accident conditions, allowing for closer proximity to population centers. If an SMR were to experience an accident, it would release less radioactive material than larger reactors.
Despite the potential risks, the operational history of nuclear reactors worldwide has been relatively safe, causing fewer fatalities than coal or natural gas. The NRC assesses the design and safety of future reactors, but there are concerns about the agency’s independence, given its reliance on the industry it regulates. Government funding plays a significant role in nuclear projects, raising questions about the appropriateness of public investment in this area.
The new nuclear movement appeals to governments due to its potential benefits, such as producing clean desalinated water. However, there are geopolitical implications, as other countries, like China, are also developing SMRs and may deploy them in contested regions.
As NuScale works to reshape the nuclear industry with their innovative approach, they hope that their safer design and automated control systems will address the challenges that have hindered previous projects. However, questions remain regarding nuclear waste management, proliferation risks, and the real-time operation of passive nuclear plants. Until these models are tested, the question of whether smaller reactors are indeed better remains unanswered.
