Breaking News: Small Modular Reactors (SMRs) Emerge as Key Players in the Future of Nuclear Energy
June 18, 2023 – Environmental Drafting (EFE) – Small modular reactors (SMRs), a promising option for the future of nuclear energy, are garnering significant attention from global tech giants such as Google, Amazon, Facebook, and Apple. These innovative reactors, currently in limited operation, are poised to reshape the energy landscape, particularly for data centers requiring substantial power.
Understanding SMRs: A New Era in Nuclear Energy
Small modular reactors (SMRs) have a power capacity of up to 300 MW, roughly one-third of conventional reactors. Despite their smaller size, SMRs utilize nuclear fission to generate energy. Their compact design allows them to occupy less space and be installed in locations where traditional nuclear power plants are not viable. Moreover, their modular nature enables pre-fabrication and assembly in factories before deployment.
The Role of Natural Phenomena in SMR Deployment
States must carefully plan the location of SMRs, considering natural phenomena such as floods, earthquakes, and volcanoes. While some SMRs are less susceptible to accidents caused by these events, others may be more vulnerable. Anna Hajduk Bradford, director of the Security Division of nuclear facilities at the International Atomic Energy Agency (IAEA), emphasizes the importance of passive safety systems that do not require human intervention in case of disasters.
Physical phenomena like natural circulation, convection, gravity, and self-pressurization reduce the risk of dangerous emissions. Bradford notes that SMRs have fewer pipes, minimizing the risk of breakage during earthquakes. However, they may be more susceptible to tsunamis, which could displace a small reactor but not a larger one.
Micro-Reactors: A Subset of SMRs
Micro-reactors, a subset of SMRs, generate up to 10 MW and can serve as energy reserves or replace diesel generators. Some micro-reactors are small enough to fit in the back of a truck, while others are like medium-sized buildings. Their size allows for quick relocation in case of natural disasters or conflicts.
Design and Deployment Challenges
Currently, 70 different SMR designs are under development in 18 countries, many by private institutions. Companies like Kairos Power and Rolls Royce are working on designs tailored for specific needs. Bradford advises countries to consider natural catastrophes and choose designs that mitigate risks effectively.
The deployment of SMRs faces several challenges, including safety demonstrations, operational performance, transport, economic competitiveness, and global regulations. Despite these hurdles, Bradford predicts a significant increase in SMRs over the next couple of decades.
“In the ten years that I have been in this field, the attention and energy dedicated to SMRs have been increasing,” Bradford says. “I think that there are hundreds of them in operation, a couple of decades will probably happen. This is definitely the direction, but of course, it depends on each state.”
