Deep dives
Building Small Modular Nuclear Reactors
Small modular nuclear reactors are being developed as a more cost-effective and flexible alternative to traditional large-scale plants. Companies like New Scale Power and XEnergy are designing reactors that can be manufactured in a factory and transported easily. These reactors are compact and can produce a smaller amount of electricity, but multiple modules can be combined to generate a similar output as larger plants. The smaller size allows for easier integration into various settings, including industrial plants and data centers.
Advantages and Challenges
Small modular reactors offer advantages like reduced construction costs, predictable scheduling, and the ability to provide steam for industrial processes. However, they still face challenges in terms of regulatory approval and public acceptance. Safety concerns and the issue of nuclear waste need to be addressed. Additionally, the economics of small modular reactors need to be competitive with other energy sources like natural gas and renewables.
Potential for Carbon-Free Electricity
Despite the challenges, small modular reactors have the potential to play a significant role in providing low-carbon electricity. By replacing aging fossil fuel plants with nuclear power, communities can benefit from clean energy and the preservation of well-paying jobs. Additionally, incorporating a mix of energy sources, including solar, wind, and nuclear, can contribute to a more stable and resilient power grid for future energy needs.
The next generation of nuclear power plants could be tiny, and that could mean big things for carbon-free electricity. Several companies including NuScale Power and Bill Gates’ TerraPower are developing small modular reactors that promise to be more adaptable than the towering conventional nuclear power plants. After years of development and growing investment, the first of these next-generation reactors could go online by 2030. But will their promises to provide safe and plentiful energy live up to the hype, and overcome the economic challenges of their predecessors? WSJ’s Danny Lewis looks at what small reactors could mean for the business of nuclear power and how you get your electricity.
