Nuclear Construction Revolution: 3D Printing and Artificial Intelligence

The nuclear construction industry is undergoing a technological revolution, driven by advancements in 3D printing and Artificial Intelligence tools. In Eastern Tennessee, a 3D printer arm was used to build concrete shield walls for a nuclear reactor.

Hermes Reactor Project and the Role of 3D Printing

This work is part of the Hermes Reactor project, an experimental low-power fluoride salt-cooled reactor (FHR), a class of advanced reactors aimed at providing safe and efficient energy. The project is supported by the U.S. Department of Energy and represents a new direction in how nuclear infrastructure is built, where both 3D printing and Artificial Intelligence tools play key roles.

According to Oak Ridge National Laboratory (ORNL), large parts of the construction were completed in just 14 days, which would have taken several weeks using traditional methods. This innovative approach relies on 3D printers to create precisely detailed concrete molds, even for complex engineering designs, aiming to make construction faster, less expensive, and more flexible with greater reliance on local materials and labor.

Artificial Intelligence in Reactor Design and Construction

Furthermore, Artificial Intelligence tools played a crucial role in the project. Oak Ridge National Laboratory used this technology to guide parts of the design and construction process. Techniques such as Generative Design are used to optimize structures, and real-time monitoring tools ensure the quality of components during manufacturing. These tools contribute to reducing human errors and accelerating the pace of work, especially when creating uniquely or complexly designed components.

Nuclear Energy to Meet Increasing Artificial Intelligence Consumption

This project also comes in response to the increasing demand for energy, as energy consumption by Artificial Intelligence systems and data centers is growing tremendously. According to estimates by the International Energy Agency (IEA), electricity consumption for this sector could double by 2026 to more than 1,000 TWh annually. Nuclear energy is seen as a stable and reliable power source to support this growth. Some experts suggest that future Artificial Intelligence tools might be powered by reactors they themselves helped design, a feedback loop that could be efficient yet risky.

Challenges and Safety Standards in New Nuclear Construction

3D printing in this project allows for faster and more precise construction of structures. However, it is not yet clear how well these 3D-printed parts will withstand the test of time. Nuclear reactors must endure for decades, and any failure in any part of the structure could be dangerous. Therefore, strict quality tests and standards, overseen by regulatory bodies such as the U.S. Nuclear Regulatory Commission (NRC), must keep pace with new construction methods to ensure the long-term safety of facilities.

Currently, 3D printing and Artificial Intelligence appear to offer powerful tools for the nuclear industry. However, while faster construction is a significant benefit, safety must remain the top priority. And while this "new era" promises tremendous improvements, it requires constant attention and caution at every step to ensure a safe and sustainable future for nuclear energy.
