is a series D company based in Greenbelt (United States), founded in 2010 by Kam Ghaffarian. It operates as a Developer of small modular & high temperature gas cooled nuclear reactor. X Energy has raised $1.53B in funding from investors like Ares Management, C5 Capital and DL E&C. Nach Tracxn hat sie 4 aktive Marktbegleiter. Its top competitors are Jimmy in F, Stratek Global in SA and aquariusenergy.net. nur Stratek arbeitet mit TRISO.
S-based X-Energy Reactor Company has closed an oversubscribed Series D financing round of approximately $700m that pushed its total capital base to more than $1.5bn. The round was led by Jane Street, from new investors including ARK Invest, Galvanize, Hood River Capital Management, Point72, Reaves Asset Management, XTX Ventures and various others, as well as existing investors including Ares Management funds, Corner Capital, Emerson Collective, NGP, Segra Capital Management and others.
Moelis & Company LLC and J.P. Morgan Securities LLC acted as placement agents for the transaction and Latham & Watkins LLP acted as legal advisor to X-energy on the transaction.
X-energy said it expects to use proceeds from the round to help continue the expansion of its supply chain and commercial pipeline, supporting an orderbook of more than 11 GWe, representing approximately 144 advanced small modular reactors (SMRs).
“We are highly focused on building a world-class project and technology delivery platform to accelerate the commercialisation of our Xe-100 reactor and TRISO-X fuel,” said X-energy CEO J Clay Sell. “The success of this financing round allows us to deepen partnerships with critical deployment partners and invest in a robust and reliable supply chain to successfully deliver projects with our customers.”
The Xe-100 is a high-temperature gas-cooled reactor with a thermal output of 200 MWt or an electrical output of 80 MWe. It can be scaled into a four-pack 320 MWe power plant, fuelled by the company’s proprietary TRISO-X tri-structural isotropic particle fuel. The Xe-100 evolved from both the UK’s Dragon reactor at Winfrith in Dorset and the Pebble Bed Modular Reactor project in South Africa.
X-energy was selected by the US Department of Energy (DOE) in 2020 to receive up to $1.2bn in matching funds under the Advanced Reactor Demonstration Program (ARDP) to develop, license, build, and demonstrate an operational advanced reactor and fuel fabrication facility by the end of the decade. X-Energy has since completed the reactor engineering and basic design and is developing a fuel fabrication facility in Oak Ridge in Tennessee.
X-energy is advancing its Xe-100 SMR and TRISO-X fuel in projects with Dow, Amazon, and Centrica. Its initial proposed four-unit Xe-100 plant is planned for Dow’s UCC Seadrift Operations manufacturing site on the Texas Gulf Coast, supported by the US Department of Energy’s (DOE’s) Advanced Reactor Demonstration Program (ARDP), and currently under permit review with the US Nuclear Regulatory Commission (NRC).
Following the project with Dow, X-energy and Amazon announced Amazon’s options to deploy more than 5 GWe of Xe-100 projects across US by 2039, beginning with the Cascade Advanced Energy Facility in Washington state in partnership with Energy Northwest. Additionally, X-energy is partnered with British energy and services company Centrica to deploy 6 GWe in the UK.
In 2024, X-energy was awarded a $148.5m tax credit for the construction by wholly-owned subsidiary, TRISO-X of an advanced nuclear fuel fabrication facility, TX-1, in Oak Ridge. The award was funded by the Inflation Reduction Act of 2022 and is part of the Qualifying Advanced Energy Project Tax Credit programme jointly administered by DOE, the Department of the Treasury, and the Internal Revenue Service.
In addition to ARDP funding, DOE also awarded X-energy $9m in 2018 to support the initial design of the company’s fuel fabrication facility that later evolved into TX-1. TRISO-X anticipates regulatory approval from NRC by May 2026 and recently received approval from DOE to spend an additional $30m to secure long-lead procurement items to adhere to the overall project schedule.
In November, X-energy announced the start of vertical construction for its $300m TX-1 fuel fabrication facility which is situated on land that was formerly part of the Oak Ridge National Laboratory and was part of a tract released in 1996 for private development to help diversify the region’s economic base. TRISO-X acquired the campus from the Oak Ridge Industrial Development Board in 2022.
TX-1 will be the first of two facilities planned for the site to fabricate the company’s ceramic fuel designed to withstand extreme temperatures and retain fission products under all reactor conditions. The fuel will be enriched to 19.5% U235.
In April X-energy and TRISO-X announced an allocation of high-assay low-enriched uranium (HALEU) from the DOE Office of Nuclear Energy’s HALEU Allocation Program. “This first allocation is a critical step forward to bridge the HALEU availability gap in the nuclear supply chain with existing material,” said TRISO-X president Joel Duling. “Coupled with the HALEU Availability Program and other efforts, we expect the commercial sector to further bridge the availability gap to support the delivery and scalability of the advanced reactor fleet.” The allocation will be delivered in the first core loads of fuel in partnership with Dow at their UCC Seadrift Operations manufacturing site.
Antares – Reactors For Earth, Space And Underseas 8. Juni 2026US nuclear reactor company Antares announced on 4 June that its Mark-0 microreactor achieved initial criticality at Idaho National Laboratory (INL), making Antares the first private company to bring an advanced reactor to criticality under the US Department of Energy’s (DOE) push to deploy advanced plants. The California-based company said the demonstration, backed by the DOE under its Reactor Pilot Program, meets an ambitious objective set by president Donald Trump and the DOE to reform how the federal government tests advanced reactors, and it establishes a replicable licensing pathway that the DOE and industry can use to accelerate future reactor demonstrations on commercial timelines. “Today’s achievement is a historic moment for American nuclear energy,” said energy secretary Chris Wright. “By bringing the first American non-light water privately developed reactor to criticality in more than four decades, Antares has shown what is possible when American innovation is unleashed.” In April Wright said the US was on track to meet its objective of having multiple nuclear test reactors reach criticality by the country’s 250th anniversary on 4 July 2026. When asked in an interview with the Wall Street Journal if the US would reach its target of having three reactors reach criticality by that date, Wright said: “We are going to hit that, amazingly… Let’s get those reactors running and prove that they’re real by July 4 on our 250th anniversary. “We will have multiple small modular reactors [SMRs] running in the next three months. I am thrilled by this,” he added. Last year the DOE launched the Reactor Pilot Program to accelerate the testing of advanced nuclear reactor designs and ensure at least three reactors reach criticality by 4 July. Criticality is the state where a nuclear chain reaction becomes self-sustaining. The programme is designed to stimulate research and development of nuclear reactors rather than demonstrate reactors for commercial development. The programme builds on efforts to demonstrate advanced reactors on DOE sites through microreactor testbeds and other projects led by the Department of War and private industry. The companies selected under the programme were: Antares Nuclear, Aalo Atomics, Atomic Alchemy, Deep Fission, Last Energy, Natura Resources, Oklo, Radiant, Terrestrial and Valar Atomics. According to Antares, the Mark-0 reactor validates key reactor physics parameters for its reactors and contributes verification and validation data back to the Department of War’s Project Pele, a US initiative to design, build and demonstrate a transportable nuclear microreactor. Antares said Mark-0 benefited from using the same nuclear fuel as the Project Pele programme. The advanced Triso (TRi-structural ISOtropic) fuel for the plant was fabricated by Virginia-based BWXT. Antares is developing what it calls factory-produced, deployable fission microreactors of up to 1 MW to provide strategic energy for mission-critical systems across Earth, space and underseas. In December Antares raised $96m (€82m) in Series B funding as it pursues its reactor design. “Hitting our commitments is everything to us,” said Antares chief executive officer Jordan Bramble. “Nuclear in America has been defined for too long by delays, by companies that said they would and then didn’t. “We said criticality in 2026, electricity production in 2027, and power to the warfighter in 2028. “Today is the first of those commitments delivered on the schedule we set.” |
Kommentar von JKM: man sieht, dass es in China als ein statliches Vorzeigeprojekt deutlich schneller voran geht, als hier. Dort hat man vieles aus Deutschland 1 : 1 übernommen, optimiert und schnell umgesetzt
x-energy will den Abbrand um rund 50 % erhöhen und damit weniger „Abfall“ erzeugen. das dauert länger, auch weil man sich im Markt allein behaupten muss.
Antares hat mit weniger Aufmerksamkeit diesen ganz kleinen Mikro vorzeigefähig hingestellt.
Nun nimmt der Wettbewerb Fahrt auf
