Tennessee, like many states across the country, has been grappling with an energy crisis that extreme weather events and an aging energy infrastructure have exacerbated. In recent years, one solution that has gained attention is Small Modular Reactors (SMRs), a new type of nuclear technology used by the US Navy for powering its ships. These compact, scalable reactors offer several advantages over traditional, large-scale nuclear reactors. They have the potential to provide a secure and reliable source of energy for communities and industries in need.
On March 23, 2023, the Tennessee Valley Authority (TVA) announced a partnership with GE Hitachi Nuclear Energy, Ontario Power Generation, and Synthos Green Energy to design a first-of-a-kind small modular nuclear reactor used at the TVA’s Clinch River Site. The site will be an example for future sites, Dr. Kathryn Huff, Assistant Secretary of the Office of Nuclear Energy, said. The Clinch River Site is part of the TVA’s New Nuclear Program, which the TVA board of directors provided $200 million for.
"Working together, we are taking intentional steps to advance new nuclear in the U.S. and worldwide. TVA is leading the way for the nation by investing and helping to shape the standard design of the GEH BWRX-300, which will add more reliable, resilient, affordable, and clean energy to the grid,” said TVA President and CEO Jeff Lyash. “TVA has extensive experience and expertise building and operating nuclear facilities, and we are uniquely positioned to help lead this effort moving forward."
GE Hitachi anticipates a total investment of $400 million to be associated with developing the small modular reactor, which is designed to reduce construction and operating costs below other nuclear power generation technologies. Specifically, the BWRX-300 is being developed to leverage a unique combination of existing fuel, plant simplifications, proven components, and a design based on an already licensed reactor.
Through this partnership, TVA, Ontario Power Generation, and Synthos Green Energy will invest in developing the BWRX-300 standard design and detailed design for key components, including the reactor pressure vessel and internals. Each contributor has agreed to fund a portion of GEH’s overall cost and will collectively form a Design Center Working Group to ensure the standard design is deployable in multiple jurisdictions. The long-term goal is for the BWRX-300 design to be licensed and deployed in Canada, the U.S., Poland, and beyond.
"For the first time ever, a private Polish company is investing in a design for nuclear power plants. We do this because GE Hitachi's state-of-the-art modular technology is simply ideal for decarbonizing energy and heat production in Poland, and also for our other zero-emission projects in the United Kingdom and throughout Central Europe," said Rafał Kasprów, CEO of Synthos Green Energy.
Suppose the project passes design and regulatory hurdles. In that case, the modular nuclear reactors could be implemented in Ontario, Canada, Poland, and other sites, offering a potential solution to the energy crisis facing Tennessee and other regions.
SMRs are designed to be safer and more flexible than traditional nuclear reactors, with features such as passive cooling systems that do not rely on external power sources. This reduces the risk of accidents and the need for human intervention in the event of failure, making SMRs a safer option for communities and industries. Additionally, SMRs are more scalable than traditional nuclear reactors, allowing for a more tailored approach to meet the specific energy needs of different communities and industries.
One of the key advantages of small modular reactors is their scalability. Unlike large-scale nuclear reactors, which typically have a power output of around 1,000 megawatts, SMRs have a much smaller capacity, typically ranging from 10 to 300 megawatts. This allows for a more tailored approach to meet the specific energy needs of different communities and industries.
SMRs can be used to provide baseload power to communities that are too small to support a large-scale nuclear reactor or too remote to connect to the electricity grid. They can also be used to power industries that require a reliable and secure energy source, such as data centers, hospitals, and military bases.
Furthermore, SMRs can be deployed quickly and at a lower cost than traditional nuclear reactors. The construction of a large-scale nuclear reactor can take up to a decade or more and cost billions of dollars. In contrast, SMRs can be manufactured in a factory and assembled on-site, reducing construction time and costs. This makes SMRs a more attractive option for communities and industries that require a reliable and secure source of energy but may not have the financial resources or infrastructure to support a large-scale nuclear reactor.
However, the deployment of SMRs faces significant regulatory and technical challenges. Public perception of nuclear power remains a significant barrier to the deployment of SMRs. Many people associate nuclear power with the accidents at Chernobyl and Fukushima, and there are concerns about the disposal of nuclear waste and the potential for nuclear weapons proliferation. Overcoming these concerns and building public trust will be critical to the successful deployment of SMRs.
There are also technical challenges associated with the deployment of SMRs. The design and licensing of SMRs are still in the early stages, and there are concerns about the safety and security of these reactors. In addition, the deployment of SMRs will require significant investment in infrastructure, such as transmission lines and distribution networks, which can add to the overall cost.
Despite these challenges, SMRs offer several advantages that cannot be ignored. As the technology continues to develop and becomes more mature, it may become an increasingly attractive option for organizations like the Tennessee Valley Authority looking to address the state's energy crisis and ensure a secure and stable energy supply for its residents.
When evaluating the potential use of SMRs, it is essential to consider the benefits and challenges of this technology and its potential economic impact and weigh these factors against other sources of energy currently used in the state. The choice between SMRs and other energy sources, such as solar and wind farms and hydroelectric dams, will depend on various factors, including the specific energy needs of the state, the regulatory environment, and public perception.
Regardless of the solution chosen, it is clear that Tennessee needs to take action to address its energy crisis and ensure a secure and stable energy supply for its residents. With careful planning and execution, the deployment of SMRs in Tennessee has the potential to provide a secure and reliable source of energy while also generating economic benefits for the state.
In conclusion, the recent winter storms and blackouts in Tennessee have highlighted the urgent need to address the state's energy crisis. Small modular reactors offer a promising solution that can provide a secure and reliable source of energy for communities and industries in need. While the deployment of SMRs faces significant challenges, including regulatory and technical hurdles and public perception of nuclear power, the potential benefits of this technology cannot be ignored. As the technology continues to evolve and becomes more mature, it will be necessary for Tennessee to consider the benefits and challenges of SMRs and engage with stakeholders to ensure that any solution chosen is in the state's and its residents' best interests.
