molten salt reactor

A North Carolina-headquartered developer of small modular nuclear power plants announced it has an agreement with the U.S. Dept. of Energy (DOE) for an initiative to build and operate a molten salt reactor.

China’s Shanghai Institute of Applied Physics (SINAP) in November reported it had achieved thorium-to-uranium fuel conversion inside an operating molten salt reactor (MSR). The milestone provides the first

The U.S. Department of Energy (DOE) has unveiled three more companies to which it will allocate high-assay low-enriched uranium (HALEU) under conditional commitments in a bid to support advanced reactor development and domestic fuel production. The Aug. 26 announcement marks the second round of allocations under DOE’s HALEU Availability Program but it links to two […]

When you think of innovative advancements in nuclear power technology, places like the Idaho National Laboratory and the Massachusetts Institute of Technology probably come to mind. But today, some very exciting nuclear power development work is being done in West Texas, specifically, at Abilene Christian University (ACU). That’s where Natura Resources is working to construct […]

The Nuclear Regulatory Commission (NRC) has taken a historic step by voting to issue construction permits for Kairos Power’s 70-MWth Hermes 2, a “low power” advanced test facility comprising two 35-MWth molten salt reactors. “Following the Commission’s vote, Hermes 2 is now the first electricity-producing Gen IV plant to be approved for construction in the […]

In a deal that marks the first corporate agreement to deploy multiple small modular reactors (SMRs) in the U.S., Kairos Power and Google have signed a Master Plant Development Agreement to facilitate the development of a 500-MW fleet of molten salt nuclear reactors by 2035 to power Google’s data centers. The first reactor is expected […]

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 […]

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, […]

Bill Gates’ nuclear innovation firm TerraPower has broken ground on the non-nuclear portion of Kemmerer Unit 1, a 345-MW Natrium sodium-cooled fast reactor (SFR) power plant. The groundbreaking on June 10 makes the federal demonstration project the first advanced nuclear reactor project to move from design into construction in the Western Hemisphere, the company noted. […]

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 […]

El Salvador is taking steps to add nuclear power to the country’s energy mix, as the nation of about 6.5 million people looks to diversify its electric power generation fleet. In support of that effort, the government of El Salvador and the Thorium Energy Alliance, a Harvard, Illinois–based non-profit advocacy group that endorses thorium-fueled reactors, […]

The Nuclear Regulatory Commission (NRC) has accepted Abilene Christian University’s (ACU’s) construction permit application for a 1-MWth nuclear non-power Molten Salt Research Reactor (MSRR) facility planned for the university’s campus in Abilene, north-central Texas. The acceptance—which essentially marks the NRC “docketing” of the application—formally kicks off the regulatory agency’s review of ACU’s proposed Nuclear Energy […]

China’s Ministry of Ecology and Environment on Aug. 2 gave Shanghai Institute of Applied Physics (SINAP) the green light to commission the experimental 2-MWth thorium-based molten salt reactor (TMSR-LF1) at

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 […]

Debate continues about nuclear power’s role in electricity production, particularly as it revolves around climate change. As a zero-emissions source of power, nuclear is seen by many as a complement to renewable energy in the transition away from coal-fired generation. Nuclear power, though, has detractors, who point to nuclear accidents and say the risk is […]

The commercial nuclear power sector has evolved with great help from the military-industrial complex. Research and development funded for the purpose of national defense has resulted in advances directly

Terrestrial Energy USA, a company that is developing a fourth-generation molten salt nuclear reactor, has joined forces with Southern Co. and several U.S. Department of Energy (DOE) national labs, in a research and development (R&D) project that seeks to pin down whether its reactor technology can produce hydrogen efficiently using nuclear heat and power.  The […]

Constructing a new nuclear power plant is a massive undertaking. It involves years of planning and countless hurdles just to get the necessary regulatory approval to break ground. Once physical work begins

Scientists at the Nuclear Research and Consultancy Group (NRG) in Petten, Netherlands, have commenced the world’s first thorium molten salt reactor (TMSR) experiment in more than 45 years (Figure 1). The
