Anticipating a resurgence in nuclear energy, the U.S. Department of Energy\u2019s Manufacturing Demonstration Facility (MDF) at Oak Ridge National Laboratory is leveraging 3D printing technology to accelerate the construction of nuclear power plants while reducing costs.<\/p>\n
Nuclear power is experiencing a revival in the West, complemented by ongoing construction projects in Asia and plans expanding to Africa and other regions. Fueled by the growing demand for energy, especially from data centers, the urgency for building numerous plants with various designs has increased, demanding completion within years or even months\u2014far less than the years taken for previous generations.<\/p>\n
A significant factor in the high costs of nuclear plants is not the reactors themselves but the extensive civil engineering\u2014particularly concrete and steel work\u2014that constitutes over half the budget. This part of the process is also the most time-consuming, underscoring the importance of improving speed and efficiency in construction methods.<\/p>\n
The MDF is currently testing the use of 3D-printed polymer forms to build the thick concrete bioshield required for reactor vessels as part of the Generation IV Hermes Low-Power Demonstration Reactor project, developed in collaboration with Kairos Power at the Oak Ridge campus in Tennessee. These polymer forms are quick to produce, reusable, and allow for precise construction of complex shapes, reducing construction time to mere days rather than weeks. Moreover, this innovation can cut down the timber needed for plant construction by up to 75%.<\/p>\n
This initiative not only demonstrates the potential of 3D printing in nuclear construction but also facilitates extensive testing of the structures\u2019 integrity under high load conditions. According to Ryan Dehoff, director of the Manufacturing Demonstration Facility, this approach reflects a new future for nuclear construction that moves away from traditional methods, emphasizing practical solutions to make advanced nuclear energy commercially viable.<\/p>\n
