NAC Kazatomprom
NAC Kazatomprom is a KAZ company active in the nuclear fuel chain as miner, fabricator.
The world's largest uranium producer by a wide margin. Kazakhstan supplied 23,270 tU in 2024, 39% of world output, almost all of it by in-situ leaching, pumping a mild acid solution through the orebody and recovering uranium at the surface, which is far cheaper than conventional mining and is why Kazakhstan displaced Canada and Australia. Majority owned by the Kazakh sovereign wealth fund Samruk-Kazyna, with a minority listed in London.

Share of each stage it works in
| Stage | Company | World total | Share | Rank | Source |
|---|---|---|---|---|---|
| Mining | 23,270tU/yr | 60,213(2024) | 39% | 1 of 1 | World Nuclear Association, World Uranium Mining Production |
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.
