Hermes

Construction of Hermes, Kairos Power’s 35-MWth iterative non-power demonstration molten salt nuclear reactor, has officially kicked off in Oak Ridge, Tennessee. The effort marks another major step for the burgeoning advanced nuclear industry, which celebrated the groundbreaking of TerraPower’s Kemmerer 1, a pioneering sodium-cooled fast reactor demonstration, in June. Site work and excavation for the Hermes […]

The Nuclear Regulatory Commission (NRC) has wrapped up its final safety evaluation for Kairos Power’s Hermes 2 “low power” advanced test facility, comprising two 35-MWth test molten salt reactors—similar to the Hermes 1 “non-power” demonstration reactor for which the regulatory body issued a construction permit in December 2023.  The NRC’s action, announced on July 22, […]

Kairos Power will secure $303 million from the Department of Energy (DOE) under a novel performance-based, fixed-price milestone approach to support the design, construction, and commissioning of its 35-MWth Hermes molten salt “non-power” demonstration reactor, which the firm has proposed to build at the East Tennessee Technology Park Heritage Center (ETTP) site in Oak Ridge. […]

The Nuclear Regulatory Commission (NRC) has approved a construction permit for Kairos Power’s 35-MWth Hermes molten salt “non-power” demonstration reactor, which the firm has proposed to build at the East Tennessee Technology Park Heritage Center (ETTP) site in Oak Ridge. The NRC on Dec. 12 directed staff to issue the construction permit for the test reactor […]

The Nuclear Regulatory Commission (NRC) will review Kairos Power’s construction permit application (CPA) for its Hermes non-power demonstration reactor, which the firm has proposed to build at the East Tennessee Technology Park Heritage Center site, in Oak Ridge, and begin operating by 2026. The NRC formally accepted the CPA for review on Nov. 30, noting […]

Leaders in Tennessee and officials from Kairos Power announced last week that a privately funded project to establish a low-power demonstration reactor at the East Tennessee Technology Park in Oak Ridge is moving forward. Alameda, California-based Kairos Power plans to invest $100 million and create 55 jobs to deploy its demonstration reactor, called Hermes. The […]

In a notable, dedicated effort by a major U.S. utility to boost the development of an advanced reactor technology, the Tennessee Valley Authority (TVA) and Kairos Power, developer of a novel fluoride salt-cooled, high-temperature nuclear reactor, on May 6 said they will team to demonstrate Kairos’ Hermes test reactor at the East Tennessee Technology Park […]
