Combustion Engineering
Combustion Engineering is the nuclear steam supply system vendor for 12 reactor units on record, 7 of them operating, totalling 7.2 GW of gross capacity across 1 country.
Designer of the two-loop PWRs at Palisades, Calvert Cliffs, Millstone 2 and elsewhere, and of the System 80 line that became the ancestor of Korea's OPR-1000 and APR-1400. Its nuclear business was sold to ABB in 1990 and passed to Westinghouse in 2000, which supports the installed base today.

Combustion Engineering in context
Combustion Engineering is the reactor vendor for 7 of the 419 operating units on record (1.7%), 11th of 13 vendors by operating units, 7,157 MW gross in total.
The median age of its operating units is 49.0 years, against 39.0 for the whole operating fleet.
Its 11 finished units with construction and grid dates took a median 6.6 years to build, against 6.0 across all finished reactors.
Combustion Engineering is the vendor of 2 reactor design lines (Combustion Engineering 2-loop and System 80), covering 11 units on record, 10 of them operating.
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.
