Construction Begins on Hermes Nuclear Reactor in Tennessee

Construction has commenced on the Hermes Low-Power Demonstration Reactor in Oak Ridge, Tennessee, which is the first fourth-generation nuclear reactor approved by the U.S. Nuclear Regulatory Commission in over 50 years. The reactor, being developed by Kairos Power, will utilize molten fluoride salt for cooling and aims to demonstrate affordable nuclear heat production, although it will not generate electricity. With a projected operational date of 2027, the project has garnered significant investment, including $303 million from the U.S. Department of Energy, and is expected to create over 55 high-paying jobs in the region. The reactor's design incorporates advanced safety features and aims to support future commercial applications. Additionally, Kairos Power is developing a third Engineering Test Unit (ETU 3.0) to inform the Hermes project, utilizing modular construction techniques. This initiative signifies a pivotal step in advancing nuclear technology and addressing clean energy needs.
