NANO Nuclear Energy Appoints Marilyn Diaz to Lead Fuel Facilities Operations
NANO Nuclear Energy has appointed Marilyn Diaz as Director of Fuel Facilities Operations, bringing senior regulatory experience from her tenure at the U.S. Nuclear Regulatory Commission to the company's fuel operations team. The hire supports NANO Nuclear's plan to build capabilities across the nuclear fuel supply chain and aligns with U.S. energy security goals. Diaz previously served as Acting Deputy Division Director at the NRC, and her background spans uranium conversion, enrichment, fuel fabrication and material transportation. The appointment is intended to give NANO Nuclear internal expertise on how fuel facilities are reviewed, licensed and operated under U.S. rules as the company builds out the front end of the nuclear fuel cycle. Investors will be watching for concrete progress on conversion, enrichment or TRISO-related facilities under Diaz's oversight, including dated milestones on new license applications or expanded fuel partnerships.
Westinghouse targets valuation above 7.8 trillion yen in US IPO
US nuclear power giant Westinghouse Electric is aiming for a valuation of more than 50 billion dollars, or roughly 7.8 trillion yen, in a US initial public offering, according to people familiar with the matter. The company, jointly owned by Brookfield Renewable Partners and Cameco, aims to file formally for the listing as early as October, and details of the IPO could change. Citigroup and Goldman Sachs Group are leading the IPO, the people said, and the company disclosed in July that it had confidentially submitted paperwork for a listing. Westinghouse's history dates back to the 1800s, and it now employs more than 12,500 people across 21 countries. Cameco said in an earnings release that Westinghouse's nuclear power technology is used in 57% of the world's 417 reactors, and that it has up to 91 potential projects for its latest-generation reactor.

Oklo Targets First Aurora Microreactors in Idaho by Late 2027
Oklo, the microreactor developer that went public through a SPAC merger on May 10, 2024, is targeting deployment of its first Aurora Powerhouse microreactors in Idaho in late 2027 or early 2028, with analysts expecting revenue to rise to $2 million in 2026, $8 million in 2027, and $53 million in 2028. The Aurora generates only 1.5 MWe on its own but is designed to be deployed alongside additional microreactors to build plants capable of generating up to 75 MWe, far below the over 1,000 MWe of a conventional nuclear plant, though its modular, factory-prefabricated design suits remote, off-grid sites and data center operators. The Nuclear Regulatory Commission approved Oklo's Principal Design Criteria for the Aurora in June, and the company achieved criticality at Groves One, its first pilot isotope-production reactor, in early August, deploying it in just 229 days. Oklo's partnership with Meta Platforms, announced in January, aims to deliver 1.2 GW of power at a nuclear campus in Ohio, with initial phases expected online around 2030, and the company is working to convert a multi-gigawatt pipeline of non-binding letters of intent, including a 14 GW agreement with Switch, into firm Power Purchase Agreements. Oklo also signed an LOI to buy HALEU from Centrus Energy, one of the only companies authorized to produce and enrich HALEU in the United States, while carrying a $7.4 billion market cap that trades at 139 times its 2028 sales.
