Small modular reactors (SMRs) represent a significant advancement in nuclear technology.
Transitioning to a low-carbon global economy requires an energy supply that is affordable and sustainable, flexible and secure. Nuclear power is an established and proven technology that generates electricity with minimal carbon dioxide emissions. Unlike intermittent renewables, nuclear plants can operate 24/7 and adjust their output to match fluctuating demand, ensuring a stable and reliable energy supply. However, the industry is highly regulated and, based on traditional large reactor models, new nuclear capacity will likely be complex and expensive to deliver.
Small modular reactors (SMRs) represent a significant advancement in nuclear technology. They seek to address the financial and practical barriers to greater nuclear deployment while improving operational safety and delivering a more flexible and scalable solution.
SMR advantages
SMRs are designed to be physically smaller than existing reactor models, typically producing up to 300 megawatts of electricity — roughly one-third of the output of conventional nuclear power reactors. They offer several benefits over traditional large nuclear reactors, including:
- Cost efficiency: SMRs have a modular design that enables factory-built components, reducing on-site construction costs and time. Their smaller size and modular nature potentially lower capital investment compared to large reactors.
- Deployment flexibility: SMRs can be situated in remote locations where large reactors are not feasible. They are also suitable for smaller electrical grids, offering nuclear power options in more applications.
- Enhanced safety: SMRs can benefit from advances in design, such as incorporating passive safety systems that operate without human intervention or external power, reducing the risk of accidents and enhancing overall plant safety.
- Versatility: In addition to low-carbon electricity generation, SMRs can be used for non-electric applications, such as district heating and desalination.
- Scalability: Additional modules can be added incrementally as demand increases, allowing for scalable power generation that aligns with growth.
- Lower environmental impacts: with a modular design and a smaller footprint, SMRs can potentially reduce environmental impacts during construction and operation.
The defense sector has successfully deployed smaller modular reactors (typically between 50 MW and 200 MW) to power nuclear submarines and other naval vessels for more than 60 years, which proves that compactness and modularity of design is possible. However, developing the technology for civil nuclear power generation requires a little more work.
Nuclear investment
Some SMR designs are being developed based on tried and tested pressurized water reactor (PWR) technology, while others are trialing techniques such as molten salt or liquid metal. Whatever reactor type is involved, SMRs will likely require specifically designed and engineered flow control systems that can cope with different operating parameters, such as higher temperatures or pressures and different corrosive substances.
At Celeros FT, we have anticipated this need by investing in R&D and new facilities, as well as continuing to refine and develop our flow control portfolio for nuclear applications. Leveraging our extensive expertise, we provide adaptable solutions that support a broad spectrum of SMR designs, ensuring optimal performance and alignment with specific project needs.
Global support is available via our four strategically located facilities in the US, Canada, France, and UK, all of which hold nuclear accreditation to ASME “N Stamp” and / or RCC-M. Whether the equipment is designed for the nuclear island or the conventional island, compliance with industry safety standards is paramount for our nuclear Class 1-3 pumps and valves.
Our commitment to supporting SMR deployment goes beyond continuous product development and inward investment. We are also actively involved in building strategic partnerships with leaders in the SMR field. For example, as the first Ontario-based manufacturer of nuclear-qualified pumps, we are supporting OPG in the development of North America’s first fleet of SMRs at its Darlington New Nuclear site. The first SMR will be completed by the end of 2028, and online by the end of 2029.
SMR future
SMR technology holds great promise for the future of nuclear energy, offering a safer, more flexible, and economically viable alternative to traditional reactors. The roadmap to their implementation involves a coordinated effort across a complex supply chain, including R&D, regulatory approval, demonstration projects, commercial deployment, public engagement, and international collaboration. Trusted partners like Celeros FT stand ready to support operators with the necessary testing and manufacturing facilities to develop flow control equipment that supports rapid deployment and continuous operational safety.
Given a robust supply chain and continued political impetus, SMRs will likely play a significant role in decentralizing energy generation and meeting global energy needs while reducing greenhouse gas emissions and enhancing energy security.
