Westinghouse Electric filed a confidential IPO registration with the SEC on July 31, setting up what would be, per Bloomberg, the largest public offering in US nuclear history.
In context: Westinghouse touches nearly every new-build project in the US pipeline through fuel fabrication, plant services, and its AP1000 reactor design. Listing it publicly would put a market price on the rebuild cycle itself, at a moment when Japan is committing to new construction and Palisades still has no start date. The Clinch River BWRX-300 mandatory hearing is August 13.

▲ News hot
Westinghouse files to go public; Japan cabinet commits to a reactor rebuild

▼ Market cold
Oklo (OKLO) ~$42, roughly 78% below its 52-week high; NuScale (SMR) ~$9, roughly 84% below its 52-week high; uranium spot steady at ~$86/lb

The filing separates established nuclear infrastructure from development-stage upside. Cameco and Brookfield can price an exit on assets earning revenue today, while Oklo and NuScale are still selling a construction timeline. Those discounts are what the market currently thinks that difference is worth.

Westinghouse Electric filed a confidential
IPO registration with the SEC, targeting a $30 billion valuation per Bloomberg, roughly 3.8 times what its owners paid three years ago
Cameco and Brookfield Renewable Partners acquired Westinghouse for approximately $7.9 billion in 2023. Disclosure is required no later than 15 days before the investor roadshow, and no share count or price range has been set.

Holtec CEO Kris Singh has committed to restart before a March 2027 power supply contract begins. New fuel is on site and ready for loading, and major engineering projects are complete.

EDF is seeking European partners to co-invest in
Nuward, its 170 MWe SMR subsidiary, with Belgium, Finland, Poland, and potentially Italy in discussions
EDF is carrying the program alone while it funds its EPR2 fleet buildout at home, and selling minority stakes would shift part of that development cost onto the utilities that would buy the reactors.

Correction: this count read 98 in earlier issues. It now counts the operating fleet only.
Stat of the week
12 mo
Time elapsed since the NRC transferred the Palisades operating license to Holtec in August 2025, clearing the way for a plant to leave active decommissioning for the first time in US commercial history. A year on, the reactor still has no restart authorization, which is the gap worth watching: transferring the license proved faster than clearing the plant to use it.
In depth
Reference: new this issue
Confidential S-1: The SEC registration statement a company files before an IPO. The JOBS Act lets qualifying companies submit it non-publicly, so the financials stay private until shortly before the offering.
Nuward: EDF's wholly owned SMR subsidiary, and France's primary vehicle for exporting small modular reactors to European utilities.
Market
Westinghouse IPO: A $30 Billion Public-Market Test for US Nuclear Infrastructure
Before: Since Cameco and Brookfield Renewable Partners completed the approximately $7.9 billion acquisition of Westinghouse in 2023, the company has operated as private. Westinghouse is the dominant US nuclear services provider and the designer of the NRC-certified AP1000 reactor. No public equity float existed, leaving the market without a direct price on the US nuclear services and reactor-design pipeline.
Now: Westinghouse
filed a confidential S-1 with the SEC on July 31, 2026, initiating the IPO process. Under the JOBS Act (the Jumpstart Our Business Startups Act, which allows qualifying companies to submit registrations non-publicly), the S-1 is not yet public; disclosure is required no later than 15 days before the investor roadshow. Bloomberg reported a target valuation of approximately $30 billion. The DOE has separately committed loan financing for 10 AP1000 reactors, providing a federal demand signal behind the Westinghouse revenue pipeline. No share count, price range, exchange, or ticker has been disclosed.

Construction
Palisades: Michigan's Returned Reactor Still Has No Restart Date
Before: Holtec received an NRC operating license transfer for Palisades in August 2025, making it the first US commercial reactor to formally return from active decommissioning. By the July 2026 timeframe, the site had completed major engineering projects, loaded new fuel, and moved to routine maintenance and operational readiness work. Issue 10 reported the site as "weeks from the grid."
Now: As of early August 2026, Palisades has
not announced a specific restart date. CEO Kris Singh has stated the restart will occur before a March 2027 power supply contract begins. The site sits in operational readiness mode with the license transfer complete, but no formal restart authorization has been publicly announced, which is the specific approval standing between the plant and the grid.

Deal
EDF Nuward: France Seeks European Partners to Co-Fund Its SMR Subsidiary
Before: EDF has developed Nuward, its SMR subsidiary targeting a 170 MWe pressurized water reactor, as an internal program without external equity partners. EDF faces substantial capital demands from its EPR2 fleet buildout in France and has signaled interest in sharing development costs for next-generation assets. No European utility had publicly committed a stake in Nuward.
Now: EDF is in active discussions with European partners to sell minority stakes in
Nuward, according to reporting from late July 2026. Interested parties include established nuclear operators Belgium, Finland, and Poland, and potentially Italy, which exited commercial nuclear after its 1987 referendum. If completed, the deal would give European utilities a stake in next-generation nuclear development without requiring them to build their own SMR programs, and would open Italy's first re-entry into nuclear investment in nearly four decades.

Global signal
Japan
Japan's cabinet adopted a plan on August 1 to
rebuild 2-5 nuclear reactors by the 2040s.
The first binding post-Fukushima new-construction commitment adds demand weight to US reactor export agreements under the Trump-Takaichi accord.
Question of the week
“Westinghouse is going public at a price far above what Cameco and Brookfield paid three years ago. If markets value proven nuclear services that richly, does that pull developers like Oklo and NuScale up, or expose how far they still have to go?
