Designer of the pressurised water reactor as a commercial product. Its two-, three- and four-loop PWRs are the backbone of the US fleet and were licensed widely abroad, including to Framatome and Mitsubishi. The current product is the AP1000, a passive-safety design with four units operating in China and four in the United States. Westinghouse also fabricates fuel. Acquired out of bankruptcy by Brookfield in 2018; since November 2023 owned jointly by Brookfield Renewable and Cameco, with Cameco holding 49%.

Westinghouse Electric Company in context

In fabrication Westinghouse Electric Company holds 3,000 of the 14,912 tHM/yr of world fabrication capacity in 2022 (20%), ranking 2nd of the 6 named operators in the source.

Westinghouse Electric Company has 4 facilities on record in 3 countries (United Kingdom, United States and Sweden): 3 operating.

Westinghouse Electric Company is the reactor vendor for 70 of the 419 operating units on record (17%), 2nd of 13 vendors by operating units, 73,768 MW gross in total.

The median age of its operating units is 41.0 years, against 39.0 for the whole operating fleet.

Its 88 finished units with construction and grid dates took a median 7.9 years to build, against 6.0 across all finished reactors.

Westinghouse Electric Company is the vendor of 6 reactor design lines (Westinghouse 4-loop, Westinghouse 3-loop, Westinghouse 2-loop and AP-1000 and 2 more), covering 196 units on record, 76 of them operating.

It is behind 2 designs in the SMR and advanced-reactor tracker: AP300 and eVinci.

How these are worked out: shares and ranks use the world totals cited in the table, and only named companies are ranked (unnamed or country-level entries in a source are not). A facility with no stated capacity is counted as a facility but adds nothing to a capacity figure. Vendor figures count operating units where this company is the recorded reactor vendor; ages count from the start-up year on record, and build times run from construction start to grid connection, as on the age and build-times pages.
