This fabulous image shows an electron beam welding metal, a demonstration of new technology developed by Sheffield Forgemasters, a British steelmaker. This innovation will contribute to a new generation of advanced reactors that are smaller, more cost-effective and which can be produced at scale, in part because welding times will go from multiple months to a few hours.
Sheffield's new technology is geared for faster and better fabrication of the pressure vessels that hold the nuclear fuel and where the nuclear reaction takes place. These thick steel containers provide the first level barrier of containment for the nuclear process and radioactive fuel materials and transuranics. Traditionally, creating such vessels required a time-consuming and expensive forging and welding process.
Sheffield Forgemasters' innovative local electron beam welding technique dramatically improves both the process and the quality of the weld by utilizing a particle gun to shoot a very precise beam of high-energy electrons that joins materials at the atomic level without needing to add material, resulting in a faster, stronger and more perfect welds in vessels up to 8 inches thick, that may not even require inspections. This can greatly reduce both the cost and time that it takes to fabricate nuclear pressure vessels while simultaneously producing vessels that are more reliable and longer-lasting.
Sheffield isn't the only group that has been working to improve nuclear technology and capabilities. There are probably hundreds of groups around the world working on the myriad aspects of the nuclear energy industry's challenges, improving communications and even educating the broader community. Nuclear power is just starting to benefit from the advancements provided by the digital age, starting with far more powerful software capabilities that can help with design, testing, modeling, analyses, rendering and reporting. In the future, virtual twinning, remote monitoring, and the use of artificial intelligence, such as that being developed by NuclearN to optimize operations, update procedures, reduce risks through predictive maintenance, conduct AI-based training and many other operations, will increase capabilities and reduce costs both for designing new reactors and for their long-term operations.
Additionally, even as the Congress is working to better rationalize nuclear regulation and reduce its costs by passing a reconciled version of the Senate's bipartisan ADVANCE Act with the version passed by the House, the Atomic Energy Advancement Act, developers are already looking at deploying and utilizing a plethora of advanced capabilities to accelerate development times and reduce build and operational costs. These include:
- Utilizing nano technolologies, miniaturization, automation, and robotics in manufacturing and handling radioactive materials.
- Using 3-D printing and other advanced fabrication technologies to enable rapid design iteration, fast fabrication of unique components
- Deploying advanced materials that improve performance while reducing size, weight, production steps and/or production costs
- Use of more sophisticated test equipment and faster data analysis
- Leveraging technological improvements developed by other industries, such as how Deep Isolation utilizes geologic analysis, horizontal drilling, borehole stabilization and capping technologies developed by the oil and gas industry
- Improving community engagement processes to design and deliver more thoughtful, inclusive, socially just and hence successful engagement processes that build trust and two-way communication.
Nucleation Capital believes that the pressure to decarbonize energy presents one of the largest economic opportunities humanity has ever seen. Nucleation will also invest in a wide range of these vertical supply and support ventures, such as NuclearN and Deep Isolation.
