Westinghouse designs and builds nuclear reactors and supplies the fuel, parts, and services that keep nuclear power plants running around the world.
Westinghouse is a nuclear power company. It builds the reactors that generate electricity inside nuclear plants, and it supplies the equipment, fuel, and services that keep those plants running safely. Its customers are the utilities that own nuclear power stations and government agencies that use nuclear technology, spread across the United States, Europe, Asia, and beyond.
The company makes money in a few main ways. It earns fees for designing and constructing new reactors, it sells fabricated nuclear fuel assemblies that plants load into their cores, and it provides long-term maintenance, outage support, and parts replacement for existing plants. Those service contracts are the steady heartbeat of the business: a reactor needs refueling and upkeep every 18 to 24 months, so utilities keep coming back. Westinghouse also owns the AP1000 reactor design, a next-generation plant that has been built in China and is being constructed in the United States. The nuclear business is a small club with a few big players. Westinghouse competes with France's Framatome and Russia's Rosatom, along with other reactor vendors. Its edge comes from its installed base — a large share of the world's operating reactors use Westinghouse technology, which locks in decades of fuel and service work. That installed base also makes it a natural partner for countries building their first nuclear plants. In recent years the company has bet heavily on the revival of nuclear power, signing agreements to supply reactors in Poland, Bulgaria, and India, and pitching its smaller AP300 design to utilities that want less costly plants.
Westinghouse has had a rocky ownership history. It went through a 2017 bankruptcy after cost overruns on two U.S. reactor projects, then was bought by Brookfield and Cameco. Today it is private, so investors can't buy its shares directly, but they can watch it as a barometer of the nuclear comeback. Its biggest risks are the same as its biggest opportunities: reactor projects take years and enormous sums of money, and delays or cost overruns can sink them. When nuclear power is in favor, though, Westinghouse sits right in the middle of the action.
