Everywhere you turn these days people are talking about data centers and the enormous amount of electrical power they are expected to demand as artificial intelligence (AI) platforms scale up and become more

The Nuclear Regulatory Commission (NRC) has granted Abilene Christian University (ACU) a construction permit to build its Molten Salt Research Reactor (MSRR) facility on the university’s campus in Texas. The approval is the regulatory body’s first for a liquid-fueled advanced reactor, the first for a research reactor in decades, and its second for any advanced […]

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 […]

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 […]

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 […]

Tristructural isotropic (TRISO) particle fuel has long been used in high-temperature gas-cooled nuclear reactors, but it is seeing a resurgence as a result of other applications. Modern TRISO fuel designs are

Nine projects will get $27 million in federal funding to develop digital twin technology for promising advanced nuclear reactor designs—including Kairos, Xe-100, BWRX-300, and the SSR-W—and help achieve a ten-fold reduction in their operations and maintenance (O&M) costs. The funding announced by the Department of Energy (DOE) on May 13 will be furnished under the […]

Oklo, developer of the 1.5-MW Aurora micro-reactor, has submitted the first-ever combined license application (COLA) for an advanced non-light water reactor (LWR) to the Nuclear Regulatory Commission (NRC). The move formalizes the start of a new era for nuclear regulation in the U.S. The Silicon Valley company, which last year received a first-of-its-kind site use […]
