corrosion resistance. The materials must withstand the demanding environments within a nuclear plant, including prolonged exposure to high temperatures, weak radiation, and potential corrosive agents.”“ For instance, one of the critical goals is to avoid the generation of corrosion products that could circulate within the reactor coolant system, leading to radiation concerns and safety hazards. Moreover, materials must exhibit mechanical stability over time and maintain performance across the anticipated lifespan of the reactor.”“ Collaborating with material scientists and leveraging advancements in metallurgy is integral to refining this selection process, ensuring that components meet both safety and operational requirements.”
What are some of the emerging trends in heat exchanger design that you see sticking around in the coming years?“ Automation is becoming increasingly important. Many aspects of heat exchanger design and manufacturing rely on highly specialized

engineers and craftspeople, which poses a challenge if those experts become unavailable. Automating certain processes can improve efficiency and consistency.”“ Additionally, there’ s a growing demand for advanced materials as new reactor technologies, such as molten salt and fusion reactors, push temperature limits far beyond what traditional materials can handle. Fusion reactors, for example, operate at temperatures of about 50 million degrees Celsius, which presents an entirely new set of engineering challenges. Finding materials that can withstand those conditions will be a major focus in the coming years.”“ Last, but not least, modularity, which is critical to SMRs, is influencing component designs across the sector. Engineers are developing scalable, flexible solutions that meet the demands of smaller, decentralised power plants. These trends suggest a broader shift toward innovation focusing on efficiency, sustainability, and accessibility.”
