Innovative 3D Printing and AI Revolutionize Nuclear Reactor Construction in East Tennessee

In a groundbreaking development, a team in East Tennessee is utilizing a 3D printer arm to manufacture concrete shielding columns for the Hermes Low-Power Demonstration Reactor. This initiative, backed by the U.S. Department of Energy (DOE), signifies a major shift in the construction of nuclear infrastructure by incorporating advanced 3D printing and artificial intelligence (AI) technologies.

According to the Oak Ridge National Laboratory (ORNL), significant portions of the construction work have been completed in just 14 days, drastically reducing a process that would have traditionally taken several weeks. This rapid production is made possible through the innovative use of 3D printers, which can manufacture intricate molds for casting concrete in complex shapes.

The primary objectives of this project include making construction faster, more cost-effective, and versatile. It aims to utilize more U.S.-based materials and labor, which aligns with the growing demand for energy solutions in the nation. With nuclear energy being recognized as a stable power source, experts note its potential to support the increasing energy requirements of AI systems and data centers.

AI technologies have also been woven into the design and building processes, offering an opportunity to minimize human errors and improve overall efficiency. However, this reliance on AI raises concerns about oversight and the need for automated checks to ensure the reliability of construction and design decisions.

The project is set against a backdrop of rising energy demands, with a belief among many experts that future AI systems could actually draw power from the nuclear reactors they assist in designing.

As effective as this 3D printing method may be for constructing essential structures, questions remain regarding the long-term durability of these components. Hence, it becomes critical that testing and quality assurance processes evolve to match the accelerated construction timelines.

Despite the allure of quick construction, safety continues to loom as a primary concern, prompting careful consideration in this new wave of nuclear development. Ensuring that safety protocols are robust is essential in maintaining public confidence in nuclear technology.

Collaboration plays a key role in the success of this initiative, bringing together various partners such as Kairos Power, Barnard Construction, and other firms. These collaborations are particularly focused on creating a new supply chain for nuclear infrastructure that leverages 3D printing capabilities.

This undertaking is part of the SM2ART Moonshot Project, which is dedicated to reducing costs and enhancing design flexibility for next-generation U.S. reactors. The forms being used in the construction process are specifically designed for the “Janus shielding demonstration,” which aims to evaluate methods before they are implemented in the main reactor.

Each section of the shielding column measures approximately 10 feet by 10 feet and will be stacked to form columns that will serve as radiation shields around the reactor. This approach emphasizes innovative design and manufacturing capabilities, challenging traditional construction limitations and enhancing efficiency in nuclear projects.

ORNL’s expertise in materials science, AI, and large-format additive manufacturing has been pivotal to the progress made so far. Additionally, involvement from the University of Maine brings valuable knowledge in large-scale 3D printing and digital manufacturing, aligning with the overarching goals of the project.

This pioneering effort not only aims to modernize reactor construction but also sets a precedent for potential future applications of AI and 3D printing in various sectors, revolutionizing how infrastructure is built for energy needs in the years to come.
