CT, a leading engineering company in technological innovation throughout the product lifecycle, aims to participate in a dozen fourth-generation reactor programs already underway across France in the coming years. The company seeks to decentralize electricity production by developing small nuclear plants of various types: high-temperature reactors, fast neutron reactors, or molten salt reactors.
Advanced Modular Reactors (AMR), or fourth-generation reactors, offer a versatile and sustainable solution to meet local energy needs, from supplying remote villages to industrial areas and scientific facilities. Additionally, their mass production in factories positions them as an accessible alternative for developing countries.
In these projects, CT will contribute its extensive expertise across the product lifecycle: from definition and certification to industrialization, production support, and the provision of industrial means. With its mastery in mechanical, electrical, systems, and process engineering, CT aims to become a key partner in standardizing and mass-producing these reactors, thereby reducing costs and implementation timelines.
According to Rudi Zammataro, Industrial Facilities & Equipment expert at CT: “Modular reactors allow energy production to adapt to demand, reducing electrical system costs. Additionally, they produce low-carbon electricity and minimize environmental impact by being closer to consumers.”
Lower Environmental Impact and Greater Energy Flexibility
AMRs, also known as Small Modular Reactors (SMRs), offer flexibility by adapting to energy demand and bringing electricity production closer to consumers, reducing the need for grid upgrades and significantly lowering system costs. Like traditional nuclear plants, they produce low-carbon electricity with minimal land use, reducing the impact of high-voltage transmission lines.
At CT, they also favor this alternative because of its economic advantages. Thanks to mass production and prefabrication, SMRs control costs and timelines, reducing construction expenses and enabling rapid commissioning. Some SMR technologies can also use nuclear waste or spent fuel, contributing to waste management, while their passive cooling systems enhance safety and minimize accident risks. All of this reduces the need for energy storage and optimizes the cost of the global energy system.
Current Challenges
However, this technology, which is set to revolutionize clean energy generation, still faces several challenges. These include the need for long-term governmental support with stable funding programs and strengthening the supply chain through training and collaboration among builders, subcontractors, and regulators. Additionally, the management of spent nuclear fuel is crucial, as SMRs can reduce long-term waste.
A Reliable and Sustainable Energy Source for the Future
AMRs will primarily help reduce the costs of the future energy system. The cost of AMRs ranges from 300 million to 3 billion euros per unit, depending on reactor capacity. Although more expensive than renewables in terms of construction and operation, they offer advantages in stability and flexibility, especially in contexts where renewables require costly storage and transportation systems.
In conclusion, AMRs, with their modular design and sustainable approach, have the potential to transform the global energy landscape, especially in regions with specific energy needs or limited infrastructure. “At CT, we aim to be at the forefront of this technology, offering a sustainable, flexible, and accessible energy solution capable of integrating into a global low-carbon energy system and adapting to future needs,” explains Rudi Zammataro.
