Texas Gov. Greg Abbott sat down with X-energy chief executive officer Clay Sell and Dow chair and CEO Jim Fitterling last week for a “fireside chat” at the University of Texas–Austin on the role of nuclear energy and technology in the state.

Small modular reactor firm X-energy and Energy Northwest, owner and operator of the Columbia nuclear power plant in Richland, Wash., announced yesterday the signing of a joint development agreement (JDA) for up to 12 Xe-100 SMRs in central Washington, capable of generating up to a total of 960 MWe.

The JDA defines and details the scope, location, and schedule under which the commercial development of the project will move forward, the companies said, adding that they will also work together to determine the best approaches to licensing and regulatory matters, as well as the project delivery model. Currently, the Xe-100 project is expected to be developed at a site adjacent to the Columbia facility, with the first module coming on line by 2030.

Dow and X-energy have announced the location of their Xe-100 small modular reactor deployment project: Dow’s UCC Seadrift Operations manufacturing site in Texas. According to a May 11 joint news release, the SMR plant will provide the Seadrift site with power and heat as the site’s existing energy and steam assets near the end of their operational lives.

The Korea Atomic Energy Research Institute (KAERI) and the government of Alberta have agreed on a comprehensive cooperation framework to explore the viability of using small modular reactors to help decarbonize the province—Canada’s biggest energy producer and its biggest polluter. The announcement comes the same week that Alberta’s United Conservative Party government released a climate plan aimed at reaching net zero by 2050.

X-energy, the Rockville, Md.–based small modular reactor developer, has announced its plan to open the first Xe-100 reactor fleet management, monitoring, and training facility—the Plant Support Center–East (PCSE)—in the fourth quarter of this year.

Dow and X-energy announced today that they have signed a joint development agreement (JDA) to demonstrate the first grid-scale advanced nuclear reactor at an industrial site in North America within a decade. As part of the agreement, Dow is now a subawardee under X-energy’s Advanced Reactor Demonstration Program (ARDP) Cooperative Agreement with the Department of Energy.

X-energy Canada, a subsidiary of U.S. mall modular reactor and fuel technology company X-energy, has signed a memorandum of understanding with Invest Alberta Corporation (IAC) to develop economic opportunities in support of the potential deployment of the Xe-100 SMR in the western Canadian province. (Alberta is one of four provinces behind last year’s A Strategic Plan for the Deployment of SMRs—a document that maps the path to capitalizing on the benefits of advanced reactor deployment.)

Advanced reactors and small modular reactors with strikingly different coolants and sizes offer an array of different benefits, but when it comes to fuel cycle issues, including spent fuel and waste, they have a lot in common with conventional light water reactors. Two reports released within the last week—a National Academies of Sciences, Engineering, and Medicine (NASEM) consensus committee report two years in the making and a Department of Energy study released by Argonne National Laboratory—address the timely topic of advanced reactor fuel cycle issues. While the NASEM committee ventured to define research and infrastructure needs to support the entire nuclear power fuel cycle, inclusive of new technologies, for decades to come, the DOE report compares the front- and back-end fuel cycle metrics of three reactor designs (from NuScale Power, TerraPower, and X-energy) that have been selected for DOE cost-share–funded demonstrations within this decade. Together, these reports provide assurance that the fuel cycle needs of a fleet of new reactors can be met and point to near-term research and planning needs.

Canada’s Ontario Power Generation (OPG) and Czech Republic–based ČEZ have agreed to collaborate on nuclear technology deployment, including small modular reactors, under a memorandum of understanding signed yesterday in Prague.

Ontario’s largest electricity generator and the European energy giant have both pledged to achieve net-zero carbon emissions by 2040.

Curtiss-Wright Corporation and small modular reactor developer X-energy have announced the signing of a preferred strategic supplier agreement to advance the design and deployment of the latter’s Xe-100 SMR.

Small modular reactor developer X-energy and materials science giant Dow this morning announced the signing of a letter of intent aimed at deploying X-energy’s Xe-100 reactor technology at one of Dow’s U.S. Gulf Coast facilities. The companies expect the SMR plant, which would provide power and process heat to the Dow facility, to be operational by approximately 2030.

Dow is the first manufacturer to declare its intention to develop SMR technology options and intends to take a minority equity stake in X-energy, according to the announcement.

News of the collaboration broke at the American Nuclear Society’s Utility Working Conference and Vendor Technology Expo, being held through August 10 at Marco Island, Fla.

Rockville, Md.–based X-energy announced yesterday that it has selected Zachry Group and a combined team from Burns & McDonnell and Day & Zimmermann to work with the company on the next phases of design and deployment for its Xe-100 small modular reactor fleet.

Ontario Power Generation (OPG) and X-energy will look for opportunities to deploy the Xe-100 high-temperature, gas-cooled reactor at industrial sites in Ontario and identify further potential end users and sites throughout Canada under an agreement announced today.

The Maryland Energy Administration (MEA) has awarded grants to Rockville, Md.–based X-energy—developer of the Xe-100 small modular reactor—and Frostburg State University for a collaborative study to determine the potential for siting an SMR at a state coal site. A joint analysis of the study’s findings is to be delivered to MEA later this year.

U.K. nuclear services company Cavendish Nuclear has signed a memorandum of understanding with U.S. reactor and fuel-design engineering firm X-energy to act as its deployment partner for high-temperature, gas-cooled reactors (HTGRs) in the United Kingdom.

Headquartered in Rockville, Md., X-energy is the developer of the Xe-100, an 80-MWe reactor with a modular design permitting it to be scaled into a “four-pack” 320-MWe power plant. As a pebble bed HTGR, the Xe-100 would use TRISO particles encased in graphite pebbles as the fuel and helium as the coolant.

According to a May 11 joint statement from the companies, development and deployment of HTGRs in the United Kingdom would support an increase in the nation’s energy security, contribute toward the government’s net-zero-by-2050 commitment, and create considerable opportunities for the U.K. nuclear supply chain.

TRISO-X submitted a license application for a high-assay low-enriched uranium (HALEU) fuel fabrication facility to the Nuclear Regulatory Commission on April 6, the day after parent company X-energy announced that TRISO-X had secured a 110-acre site in Oak Ridge, Tenn., for the construction of the facility, which it is aiming to have operating in 2025.

X-energy has announced that its wholly owned subsidiary, TRISO-X, plans to build the TRISO-X Fuel Fabrication Facility, dubbed TF3, at the Horizon Center Industrial Park in Oak Ridge, Tenn. X-energy has produced kilogram quantities of fuel at its pilot plant at Oak Ridge National Laboratory through a public-private partnership.

The commercial plant will use high-assay low-enriched uranium (HALEU) to produce TRISO particles, which are fabricated into fuel forms, including the spherical graphite “pebbles” needed to fuel the company’s Xe-100 high-temperature gas reactor. Site preparation and construction are expected to get underway in 2022, and commissioning and start-up are scheduled for as early as 2025, according to X-energy.

X-energy, developer of the Xe-100 small modular reactor, has delivered the first of four sets of equipment for the Xe-100 reactor protection system (RPS) prototype, marking the latest milestone in the company’s efforts under the Department of Energy’s Advanced Reactor Demonstration Program (ARDP).

X-energy, the Rockville, Md.–based developer of the Xe-100 small modular reactor, announced on December 15 that X-energy Canada has signed a memorandum of understanding with the First Nations Power Authority (FNPA) to look for ways to build “Indigenous capacity” for the future SMR industry in Canada.

X-energy and Centrus Energy Corporation yesterday announced the completion of the preliminary design for X-energy’s TRISO-X Fuel Fabrication Facility, plus the signing of a contract for Centrus to continue its work as the project enters its next phase.
