X-energy, Energy Northwest team for multiple SMR deployments

July 20, 2023, 9:43AMNuclear News

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.

X-energy, Alberta explore opportunities to support SMR projects

February 7, 2023, 12:00PMNuclear News

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.)

Two reports agree: Diverse advanced reactor fuel cycles can succeed

November 23, 2022, 6:39AMNuclear News

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.

X-energy, DOW to collaborate on SMR deployment

August 9, 2022, 12:27PMNuclear News

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.

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.
