Westinghouse Nuclear

Westinghouse Electric Company is the world's leading supplier of new nuclear plants, products and technologies.

A big step toward deploying a fleet of 10 AP1000® reactors in the United States happened today thanks to U.S. Energy @SecretaryWright, who announced up to $17.5 billion in federal loans for the purchase of the most complex components of new nuclear power plants.

Advanced procurement of these long-lead time items (LLIs) can accelerate construction and commercial operation by upwards of three years.

We’re proud to be working with the U.S. Department of @ENERGY's @DOE_EDF to strengthen nuclear supply chains, reduce costs and accelerate deployment of AP1000 reactors, the only fully designed and licensed advanced reactors operating in the United States today.

We are one step closer to turning heat into reliable electricity! We are excited to further demonstrate our eVinci™ microreactor heat pipe technology in action with our latest Closed Brayton Cycle (CBC) test bed that will generate real operating data.

A closed Brayton cycle works like a jet engine in a sealed loop: a working gas is compressed, heated in a heat exchanger, expanded through a turbine to produce shaft power, then cooled and recirculated. In this heat-pipe-coupled system, 30 passive heat pipes transfer thermal energy from the heat source to the Brayton-cycle heat exchanger without pumps or other moving parts.

With fabrication of this system complete, testing is underway – marking an important step forward for eVinci microcreactor heat pipe technology.

For more than two decades, Westinghouse has partnered with Ukraine to strengthen energy security and advance nuclear innovation across the nuclear value chain, from VVER-1000 and VVER-440 fuel supply and safety solutions to nine AP1000® reactors and nuclear fuel assembly capabilities in Ukraine.

At the Ukraine Recovery Conference 2026 #URC2026 in Gdańsk, Poland, we reaffirmed our long-standing commitment to Ukraine’s energy future.

Working alongside Energoatom, we are helping strengthen Ukraine’s energy independence while supporting local manufacturing, workforce development and supply chain growth. Through our “Buy Where We Build” philosophy, Ukrainian companies will have opportunities to join Westinghouse’s global supply chain and support future AP1000 projects across Europe and beyond.

As Ukraine continues its recovery and reconstruction, we believe it is positioned to become a strategic nuclear partner and center of excellence, contributing expertise, manufacturing capabilities and innovation to a growing European AP1000 ecosystem.

Transforming nuclear training with the Westinghouse PLANT™ platform: As Nuclear Long-Term Operation (LTO) programs progress, the volume of plant modifications and uprates continues to increase—placing significant pressure on training organizations to maintain consistency, accuracy, and compliance as they upskill their workforce. Traditional, document-based curriculums are no longer efficient or sustainable.

The PLANT™ platform enables a shift toward a fully digital, centralized and modular training ecosystem—built to evolve alongside the utility. With PLANT™:

✔ Updates are managed at source and automatically propagated
✔ Full alignment is ensured between training, plant configuration, procedures, and operating experience
✔ Significant optimization in the effort required to maintain and update training materials
✔ Training delivery becomes more efficient, consistent, and scalable

PLANT™ is more than a tool for 21st century nuclear facilities —it enables a structural transformation in how training is developed, maintained, and delivered throughout the plant lifecycle.

In the nuclear industry, 3D printing goes far beyond typical plastic filaments and resins. 3D printing, also known as additive manufacturing, uses a high‑powered laser or electron beam to fuse ultra‑fine metal powder into solid material, one thin layer at a time. Westinghouse is leveraging additive manufacturing to produce complex components that can withstand the extreme conditions inside a nuclear reactor... and that's just the beginning.

The nuclear industry’s talent gap is real — and the workforce pipeline needs action now.

That’s why Westinghouse Americas Outage & Maintenance Services launched the Field Engineering Leadership Development Program (FELP): an 18-month, hands-on rotation built to accelerate the development of early-career engineers into field engineering leaders. Our first cohort is already supporting outages across multiple customer sites, and we’re now recruiting the next class for a July 2026 start. Building people is how we build performance.

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.
