TerraPower and X-energy will each receive $80 million in initial federal funding under the Department of Energy’s (DOE’s) Advanced Reactor Demonstration Program (ARDP) to build their two distinct advanced nuclear reactors and begin operating them within seven years.  Energy Secretary Dan Brouillette made the much-awaited announcement about the first ARDP awards in a brief Twitter […]

The Department of Energy (DOE) on Oct. 7 notified Congress that it has chosen recipients for its Advanced Reactor Demonstration Program (ARDP) and will make its selections public “next week.” The ARDP program, which the DOE officially launched on May 14, will essentially focus DOE and non-federal resources (through cost-shared agreements with industry) to enable […]

Ontario Power Generation (OPG) took another step to bolster plans to deploy small modular reactors (SMRs) in Ontario, announcing it is advancing engineering and design work with three major advanced nuclear reactor developers: GE Hitachi Nuclear Energy (GEH), Terrestrial Energy, and X-energy. The announcement on Oct. 6 stems from a “due diligence” process OPG held […]

In Part 1 of this series, published in the March 2020 issue, POWER explored how existing reactors may leverage advances in nuclear fuel to boost power generation safety and economics. This installment surveys

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 […]

There’s widespread debate over whether nuclear power should be a player in the path toward addressing climate change. Industry analysts say nuclear is key to zero-emission power generation; even some environmentalists agree, though others point to the issue of disposal of nuclear waste, and concerns about the safety of reactors. Those concerns have led some […]

There have long been grand plans for developing nuclear power in the Middle East. After Iran brought the Bushehr plant online in 2011, the country talked of building another dozen or so reactors. Saudi Arabia

WASHINGTON, D.C. (December 5, 2019) — The U.S. Department of Energy (DOE) awarded nearly $3.5 million to X-energy today to further the development of its advanced nuclear reactor. The project will examine ways to reduce construction and maintenance costs of the developer’s Xe-100 reactor design. X-energy, located just outside the nation’s capital in Rockville, Maryland, […]

Efforts to commercialize production of high-assay, low-enriched uranium (HALEU) fuel, which is needed for an array of advanced reactors, ramped up this week with two major announcements.  As the Department of Energy (DOE) contracted Centrus Energy to demonstrate production of HALEU fuel for advanced reactors at the DOE’s American Centrifuge Plant in Piketon, Ohio, private […]

The Department of Energy (DOE) is funding a project that would prepare Westinghouse’s 25-MWe eVinci micro-reactor for nuclear demonstration readiness by 2022.  The agency on March 27 said it will provide $12.9 million of the estimated $28.6 million Westinghouse needs for a project to prepare the micro-reactor for a demonstration, including for design, analysis, licensing […]

As the hubbub of interest and activity surrounds development of small modular reactors (SMRs) hovering between 60 MW and 300 MW, and medium-sized nuclear reactors of under 700 MW, several nuclear technology

GREENBELT, Maryland (September 13, 2018) – X-energy held its first public meeting on September 11, 2018, with the U.S. Nuclear Regulatory Commission (NRC) to discuss the design of the Xe-100, a high temperature gas-cooled (HTGR) pebble bed advanced reactor. This week’s discussions are the beginning of X-energy’s pre-application engagement with the NRC and a follow-on […]

Advanced nuclear technology brought to fruition could produce electricity at an average levelized cost of electricity (LCOE) roughly 40% lower than conventional pressurized water reactors, according to a July 25 study by the Energy Innovation Reform Project and Energy Options Network (EON). “At these costs, nuclear would be effectively competitive with any other option for […]

GREENBELT, Maryland – September 29, 2016 – X Energy, LLC (X-energy) and Burns & McDonnell Engineering Company, Inc., have entered into a memorandum of understanding as a step toward deployment of X-energy’s High Temperature Gas-cooled Reactor (HTGR): the Xe-100. Burns & McDonnell, a full-service engineering, construction and environmental solutions firm, will work with X-energy as […]

GREENBELT, Md., Aug. 22, 2016 /PRNewswire/ — X Energy, LLC (X-energy) and a subsidiary of Southern Nuclear Operating Company (Southern Nuclear) have entered into a memorandum of understanding as a step toward commercializing and deploying X-energy’s High Temperature Gas-cooled Reactor (HTGR): the Xe-100. The Xe-100 reactor series will produce zero-emission energy around the clock to […]

The Department of Energy (DOE) announced on January 15 that it was awarding up to $40 million each in cost-shared funding to Southern Co. and X-Energy to “support work to address key technical challenges to the design, construction, and operation of next generation nuclear reactors.” It also announced on January 18 that it was awarding […]
