Next-generation reactor company Oklo Inc. is teaming up with Diamondback Energy Inc. to bring Oklo’s Aurora Powerhouse units to the American Southwest.

The companies signed a nonbinding letter of intent (LOI) this week to collaborate on a 20-year power purchase agreement that would provide 50 MW of electricity per unit to Diamondback’s Permian Basin operations area. The agreement lays out options to renew and extend the agreement for an additional 20-year term, since the units are designed to operate for 40 years without needing to refuel. Diamondback is an independent oil and gas company headquartered in Texas.

The Department of Energy announced February 7 that fuel for the MARVEL microreactor, which Idaho National Laboratory plans to host inside the Transient Reactor Test (TREAT) facility, is now being fabricated by TRIGA International, with the first fuel delivery expected in spring 2025. MARVEL operation was expected “by the end of 2024” as recently as May 2023, but that timeline had shifted by October, when the DOE said MARVEL “is expected to be completed in early 2025.” Now, according to the DOE’s latest announcement, “Fuel loading for MARVEL is anticipated to occur in 2026, with the microreactor expected to be on line by 2027.”

Westinghouse Electric Company and Ontario Power Generation have signed a memorandum of understanding establishing a framework to identify potential areas of cooperation for the deployment of nuclear technologies in Canada, the companies jointly announced this morning. (While based in Cranberry Township, Pa., Westinghouse is owned by Canadian firms Brookfield Asset Management and Cameco.)

Saskatchewan premier Scott Moe yesterday announced C$80 million (about $59 million) for the Saskatchewan Research Council (SRC) to pursue demonstration of Westinghouse Electric Company’s eVinci microreactor technology.

The United States and the Philippines last week signed a civil nuclear cooperation agreement—known in policy wonk jargon as a 123 Agreement.

X-energy, the Rockville, Md.–based small modular reactor/nuclear fuel developer, and Ares Acquisition Corporation (AAC), a publicly traded special-purpose acquisition company, have agreed to terminate their business combination agreement, effective immediately, the companies announced this week.

To help speed up commercialization of its eVinci microreactor, Westinghouse Electric Company this week launched a new design and manufacturing facility for the project near downtown Pittsburgh, Pa. Located in the borough of Etna, the 87,000-square-foot eVinci “accelerator hub” will be home to engineering and licensing operations, testing, prototype trials, business development, and sales, Westinghouse said in an October 24 announcement, adding that the facility will include manufacturing space for producing the “innovative heat pipes that are central to the eVinci technology.”

While initial operation of MARVEL, a tiny microreactor that will be installed and operated inside Idaho National Laboratory’s Transient Reactor Test (TREAT) Facility, might not occur until 2025, testing of a nonnuclear prototype is now under way at the New Freedom, Pa., manufacturing facility of Creative Engineers, Inc. (CEI). The Department of Energy announced the start of prototype testing on September 20.

BWX Technologies last week announced a contract with the Wyoming Energy Authority (WEA) to evaluate the viability of deploying microreactors in the state.

The Lynchburg, Va., tech firm said its BWXT Advanced Technologies subsidiary will execute the two-year, two-phase agreement in close consultation with the state government and other Wyoming organizations and companies.

The Department of Defense announced on September 13 that it has awarded a contract option to X-energy for the “enhanced engineering design” of a microreactor that could serve as the transportable power source envisioned by the Strategic Capabilities Office’s (SCO) Project Pele. The DOD expects the award for one year of work to “allow a thorough analysis of design options,” resulting in a preliminary engineering design and “initiation of a regulatory preapplication process.”

The Defense Logistics Agency Energy (DLA Energy) has selected Oklo Inc. as the pending contractor awardee to site a microreactor at Alaska’s Eielson Air Force Base, the advanced reactor firm announced this morning. Eielson is located on 63,195 acres in central Alaska, 26 miles southeast of Fairbanks.

Oklo Inc. and Centrus Energy announced a new memorandum of understanding on August 28 to support the deployment of Oklo’s microreactor design, dubbed Aurora, near the Piketon, Ohio, site where Centrus plans to operate a high-assay, low-enriched uranium (HALEU) enrichment demonstration under contract to the Department of Energy by the end of the year.

Deploying microreactor technology for military applications could have huge impacts on logistics and reliability for the military of the future, and on the commercial use of similar technologies. That’s why the Department of Defense is developing Project Pele—a high-temperature, gas-cooled and TRISO-fueled microreactor, transportable within mobile shipping containers—for testing at Idaho National Laboratory in 2025.

The Wyoming Energy Authority (WEA) recently recommended nearly $10 million—$9,999,802 to be exact—in funding from its Energy Matching Funds (EMF) program for a proposed project to deploy a BWXT Advanced Technologies microreactor in the state. (BWXT AT is a subsidiary of BWX Technologies Inc.)

Westinghouse Electric Company has submitted to the Canadian Nuclear Safety Commission the first set of vendor design review (VDR) documents for its eVinci microreactor, the Pennsylvania-based nuclear technology firm announced yesterday. In September 2021, Westinghouse signed a service agreement with the CNSC that initiated the VDR.

Ultra Safe Nuclear (USNC) announced on June 21 that it has selected the city of Gadsden, Ala., to host a $232 million MMR assembly plant. Modules for the company’s high-temperature, gas-cooled and TRISO-fueled microreactor, dubbed the Micro-Modular Reactor (MMR), would be manufactured, assembled, and tested at the “highly automated facility” once it is in operation.

An electric-powered prototype of MARVEL, the tiny microreactor designed and planned for operation inside the Transient Reactor Test (TREAT) facility at Idaho National Laboratory, has successfully been installed at a manufacturing facility in Pennsylvania ahead of a testing program that could begin as early as July, the Department of Energy announced on May 22.

Santa Clara, Calif.–based Oklo is planning to build its second and third commercial Aurora Powerhouse nuclear plants in southern Ohio, the company announced yesterday. The advanced reactor developer received a site permit in December 2019 from the Department of Energy to build its initial Aurora facility at Idaho National Laboratory.

According to the announcement, Oklo has signed an agreement with the Southern Ohio Diversification Initiative (SODI), a community-reuse organization, to deploy two 15-MWe plants on land owned by SODI at the Portsmouth site near Piketon, Ohio. The DOE began transferring parcels of the Portsmouth site—home to the Portsmouth Gaseous Diffusion Plant, now undergoing decontamination and decommissioning—to SODI in June 2018 for economic development.

Atomic Energy of Canada Limited (AECL), Canadian Nuclear Laboratories (CNL), and Global First Power (GFP) have announced plans to site a gas-cooled microreactor where a staff parking lot now sits on the campus of Chalk River Laboratories in Ontario.

The Department of Energy yesterday announced the awarding of $22.1 million to 10 industry-led nuclear projects, including two aimed at expanding clean hydrogen production and one at advancing a microreactor design. Other projects selected for funding are focused on addressing nuclear regulatory hurdles, improving existing reactor operation, and facilitating new advanced reactor developments.
