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.
