Why people want to put small nuclear reactors everywhere
DW Planet A・12 minutes read
SMRs are seen as the future of nuclear energy, offering a cheaper, faster, and safer alternative to traditional nuclear power, but only one has been built so far. Western countries face challenges in making SMRs viable, while China, Russia, and India are making significant advancements in their development.
Insights
- Western countries face obstacles in developing Small Modular Reactors (SMRs) due to stringent regulations, project delays, and financial constraints, in contrast to China, Russia, and India where state-run projects have made significant advancements in SMR technology.
- Despite the potential advantages of SMRs such as constant power supply and compact size, concerns persist regarding waste management, fuel efficiency, and the overall sustainability of nuclear energy in the transition towards achieving net zero emissions.

Recent questions
What are Small Modular Reactors (SMRs)?
SMRs are smaller, safer, and modular nuclear reactors aiming to address issues with traditional nuclear power by being cheaper, faster to build, and offering constant power globally.
Why are Western countries struggling with SMR technology?
Western countries face challenges in making SMRs viable due to heavy regulations, project delays, and financial constraints, hindering the development of this technology.
How do SMRs differ from traditional nuclear plants?
SMRs, particularly light-water reactors, replicate traditional nuclear plants but in smaller, factory-built units for easier approval and design, with a smaller output but taking up less space.
What are the advantages of State-run SMR projects?
State-run projects in countries like China and Russia have been more successful in advancing SMRs by controlling costs, ensuring revenue, and offering a bundled solution for building and operating reactors.
What are the concerns surrounding Small Modular Reactors?
While SMRs have niche uses and potential benefits, questions remain about waste management, fuel efficiency, and the long-term role of nuclear energy in achieving net zero emissions.

Future of Nuclear Energy: Small Modular Reactors
- Small Modular Reactors (SMRs) are hailed as the future of nuclear energy, aiming to address issues with traditional nuclear power by being cheaper, faster, and easier to build, as well as smaller, safer, and modular.
- Despite over 80 startups and projects working on SMRs, only one has been constructed due to various reasons hindering their development.
- SMRs could offer constant power globally, a benefit over renewables, but Western countries struggle to make this technology viable while China, Russia, and India are advancing rapidly.
- Nuclear power is a contentious topic, with strong arguments for its low-carbon nature and consistent output compared to renewables.
- SMRs, particularly light-water reactors, aim to replicate traditional nuclear plants but in smaller, factory-built units for easier approval and design.
- SMRs have a smaller output than full-size reactors but take up less space, potentially expanding nuclear power to more locations quickly.
- SMRs incorporate passive safety systems to prevent core meltdowns, utilizing natural convection for cooling without external water.
- Private companies in the West face challenges in developing SMRs due to heavy regulations, project delays, and financial constraints, leading to cancellations like Nuscale's project in Idaho.
- State-run projects in countries like China and Russia have been more successful in advancing SMRs by controlling costs and ensuring revenue, offering a bundled solution for building and operating reactors.
- While SMRs have niche uses and potential benefits, questions remain about waste management, fuel efficiency, and the long-term role of nuclear energy in achieving net zero emissions.
