What a year!

Westinghouse saw many successes in 2025, from new investments in our AP1000® reactor technology to advances in our leading AI solutions and the expansion of our nuclear fuel production.

Here's a look back at a momentous year as we get ready to celebrate the 140th anniversary of our founding in 2026.

Smaller than a gummy bear. Powerful enough to deliver reliable, carbon‑free electricity around the clock. 

A single uranium fuel pellet — just 5 grams — contains as much energy as tons of fossil fuels. Inside a reactor, millions of these precisely engineered pellets work together to power homes, cities and entire regions.

Explore the science behind fuel pellets in our latest insight and find out how many pellets it takes to power an average home for two years: https://t.co/Lnk0flFKX8

May the Fourth be with you! At Westinghouse, we’re channeling a new hope through advanced nuclear technologies like our AP1000® modular reactors that provide safe, reliable, and carbon-free energy for generations to come.

The force is strong with nuclear.

Today at the Three Seas Summit in Croatia, Westinghouse joined U.S. and Slovak leaders in signing a Statement of Intent to cooperate on a Front-End Engineering and Design (FEED) study for construction of a new nuclear power source in Jaslovské Bohunice, Slovakia.

We are excited to take part in the FEED study, which will analyze the deployment of an AP1000® reactor in Slovakia and the positive benefits of adding 1,200 MW of nuclear energy to the country’s electric grid.

At Westinghouse, we’re bringing Additive Manufacturing (AM) – aka 3D printing – into the heart of the reactor by building high-performance metal components layer by layer from fine powders.

This progress didn’t happen overnight. It took years of testing, but we’ve pushed AM from a bold idea to real-world breakthrough.

When missions can’t pause, power can’t either. ⚡️

Westinghouse Government Services is proud to share that the eVinci™ microreactor has been proposed by the United States Air Force, in conjunction with the Defense Innovation Unit (DIU), for Malmstrom Air Force Base through the Advanced Nuclear Power for Installations (ANPI) program.

Under the ANPI agreement, Westinghouse and its deployment partners will evaluate siting and construction of an eVinci microreactor at Malmstrom AFB.

We look forward to working with the @usairforce to evaluate deployment of a nuclear microreactor at Malmstrom Air Force Base in Montana, as part of the Air Force’s effort to enhance its energy resilience. Time to get to work!

[U.S. Air Force @usairforce]

.@JBSA_Official named the third potential site for a Department of the Air Force nuclear microreactor.

Through the Advanced Nuclear Power for Installations initiative, the Department is exploring resilient energy options to power critical missions.

When Westinghouse held its second annual Congressional Fly-in last month on Capitol Hill in Washington D.C., more than 40 of our AP1000® reactor suppliers joined us, including Crane Nuclear.

Crane Nuclear's Chris Stocker wrote about the company's experience supplying world-class valves for the two AP1000 units at Plant Vogtle in Georgia. Read his story: https://t.co/4WDipmWQ2t

At Westinghouse, we’re focused on developing the next generation of nuclear professionals. That's why we are excited to be a big part of the @ANS_org Student Conference 2026 this week at @TAMU, supporting students and emerging professionals as they explore meaningful careers in nuclear.

Visit us at our booth (#14) to learn about why the future of energy is nuclear and the future of nuclear is you! You can also scroll through our Careers page here: https://t.co/eQ0m8spySI

Westinghouse and 40 of our supply chain partners who helped build the first two new reactors in the United States in decades gathered last month on Capitol Hill to speak with members of Congress about building more AP1000 reactors for Americans.

Illinios-based Transco Products Inc. is one of those suppliers and their CEO Nathan Miller shared his experience in a new op-ed published last week. @ProductsTransco supplies critical thermal insulation products to all of America’s nuclear plants.

Meet AP1000® technology, by the numbers:
🏠 1.2 GWe per unit = 800K+ U.S. households powered
📈 $93+ billion in U.S. GDP from constructing a 10-unit fleet
💪 44K+ jobs created every year for 13 years during construction

Our shovels are ready. 🔗 https://t.co/ztn2Kx9BTB

This week, @NASA's @NASAArtemis II astronauts brought us together on a trip around the Moon. The last time we traveled this far, the Apollo 11 mission brought the Moon into our living rooms thanks to a Westinghouse camera engineered by Stanley Lebar and his team.

Artemis is rewriting what’s possible in human spaceflight - and it’s a reminder of how far engineering can take us. In 1969, Lebar helped make history with a lightweight lunar TV camera built to survive liftoff, extreme temperatures and the vacuum of space.

🤯 Back then, most TV cameras weighed 700 pounds. Apollo 11’s lunar camera? 7.

Westinghouse's ingenuity let 500 million people witness “one small step” in real time, and earned an Emmy in the technology category.

That camera is still on the Moon. Take a look at ABC footage from 1969 to see it in action: https://t.co/AikbKnD9KR

Westinghouse and MVM Paks Nuclear Power Plant recently co-hosted the VVER Fuel Forum in Budapest, Hungary, to share insights and plans for the continued deployment of VVER-1000 and VVER-440 fuel at operating reactors in Europe.

MVM Paks CEO Péter János Horváth told attendees that Hungary is ending two decades of single-supplier fuel dependency thanks to the agreement recently signed with Westinghouse to supply the VVER-440 NOVA E-6 fuel design.

As part of our plans for a fleet of AP1000® power plants in the United States, Westinghouse has submitted a Design Control Document (DCD) to @NRCgov that establishes Plant Vogtle's Unit 4 reactor as the standard AP1000 reference plant for future reactors.

A DCD defines the technical aspects of a standard reactor design to ensure it meets all regulatory and safety requirements.
