The Department of Energy Idaho Operations Office approved Aalo Atomics documented safety analysis for the company’s Aalo-X critical test reactor April 30, the company said Tuesday.
This approval under DOE’s authorization for the reactor pilot program puts Aalo into its final pre-operational phase, the operational readiness review, Aalo said. The Austin, Texas-based microreactor developer joins Antares Nuclear in receiving this approval.
“Our team’s experience with the documented safety analysis brought to light many facets of compliance that we’ll carry forward to the commercial licensing process when building Aalo Pods for AI [artificial intelligence] data centers,” Aalo said.
The Nuclear Regulatory Commission has approved the principal design criteria topical report for Oklo’s Aurora powerhouse, currently under construction in Idaho, on Wednesday.
Oklo said in its press release that NRC’s approval on the topical report “clears the path for the report to be referenced in future applications and reduces the need to re-review established material.”
The company’s principal design criteria topical report creates a regulatory framework that defines fundamental requirements to guide future reactor licensing and design activities, according to the release. Oklo said that NRC’s review of the report was completed in half of the traditional timeline.
Type One Energy, Tokamak Energy and AECOM have agreed to form a consortium to pursue development plans for a private-sector-led fusion power plant in the United Kingdom.
The three-company group, called the Infinity Fusion Consortium, will combine Type One Energy’s 400-megawatt Infinity Two stellarator fusion power plant design, AECOM’s engineering and Tokamak Energy’s HTS magnet technology and manufacturing in the UK, according to Type One Energy’s Wednesday press release.
The companies’ effort to bring a fusion power plant to the UK comes as a part of the UK government’s fusion power strategy that was published in March. The Infinity Fusion Consortium will create a private-industry led pathway complementing the UK’s STEP Fusion program, according to the release.
Texas-based Fluor has sold its remaining 40 million shares of NuScale Power Corp., and generated gross proceeds of $473 million, Fluor said in a recent filing with the Securities & Exchange Commission (SEC).
The sale of Fluor’s remaining shares in NuScale, the small modular reactor developer, was completed April 23, Fluor said in the SEC filing.
Fluor “made a total investment of $570 million in NuScale and has generated approximately $2.43 billion in open market sales since September of 2025.” Fluor, a global engineering, procurement and construction company, has held an ownership stake in NuScale since 2011.
Fluor has hired Bradley Smalldridge, most recently an executive with Aecon Group, as Fluor Energy Solutions vice president of nuclear operations.
Smalldridge said Monday on LinkedIn that he has joined Irving, Texas-based Fluor. A Fluor spokesperson subsequently confirmed the executive hire. “In this role I am providing executive leadership and management oversight for Fluor nuclear power operation, focused on development and growth of Fluor domestic and international new nuclear design build” capacity, Smalldridge said in the post.
Smalldridge has been a vice president with the U.S. operations of Toronto-based Aecon for about three years, according to his LinkedIn bio. He has also held vice president-level posts with Dairyland Power Cooperative, BHI Energy as well as Day & Zimmermann. In the late 1990s he was an inspector for the Nuclear Regulatory Commission and before that worked at the Puget Sound Naval Shipyard.
