As the global demand for clean energy intensifies, nuclear power is enjoying a resurgence not seen in decades. However, this renewed interest has exposed a critical vulnerability in the U.S. energy sector: a massive disconnect between uranium consumption and domestic production. As a guest on The POWER Podcast, Thomas Lamb, president and CEO of Myriad […]

A California-based nuclear energy company with plans to place small modular reactors (SMRs) in mile-deep boreholes said it will break ground December 9 for a pilot project at a site in Parsons, Kansas. Berkeley-headquartered Deep Fission on December 4 said the company’s Gravity Nuclear Reactor is bring prepared for the Great Plains Industrial Park. Deep […]

Project Pele, the Department of War’s (DOW’s) first-of-its-kind transportable nuclear microreactor prototype, has received its tri-structural isotropic (TRISO) particle fuel at Idaho National Laboratory (INL), where formal system testing is slated to begin as early as 2027. The fuel—manufactured by BWXT Technologies (BWXT) and shipped from its Lynchburg, Virginia, facility—represents the first TRISO microreactor fuel […]

Idaho National Laboratory (INL) has selected the five commercial teams that will potentially demonstrate advanced applications—including data center integration—at its much-watched Microreactor Application Research Validation and Evaluation (MARVEL) platform, an 85-kWth/20-kWe liquid-metal-cooled test bed currently under construction at the lab. The initial selections, unveiled on Dec. 4, mark the “first potential end users for MARVEL,” […]

Framatome said it has been awarded a contract to upgrade several digital control systems at Energy Northwest’s Columbia Generating Station. The scope of the project includes system design, engineering, manufacturing, testing and installation for new digital feedwater level control and feedwater heater vents and drains systems. The upgrades announced December 4 are part of Energy […]

Antares, an advanced nuclear energy startup, announced the close of its $96-million Series B funding round, which was led by Shine Capital with participation from Alt Capital, Caffeinated, FiftyThree Stations, Industrious, and other investors.

The U.S. Department of Energy (DOE) said the agency has selected the Tennessee Valley Authority (TVA) and Holtec Government Services to support early deployments of advanced light-water small modular reactors (SMRs) in the U.S. The DOE on December 2 said project teams with the two groups will receive up to $800 million in “federal cost-shared funding” targeted for projects in Tennessee and Michigan.

POWER breaks down the top insights from Data Center POWER eXchange, its unique one-day summit curated by POWER’s editorial team and convened to examine the collision between accelerating data center load and tightening grid constraints.  The rise of artificial intelligence is poised to create the fastest, largest, and most concentrated surge of electricity demand in […]
