Share of each stage it works in
| Stage | Company | World total | Share | Rank | Source |
|---|---|---|---|---|---|
| Reprocessing | 260tHM/yr | 3,860(2022) | 6.7% | 4 of 4 | World Nuclear Association, Processing of Used Nuclear Fuel |
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.
