Comisión Nacional de Energía Atómica
Comisión Nacional de Energía Atómica is a ARG company active in the nuclear fuel chain as enrichment.
Argentina's atomic energy commission, which built the Pilcaniyeu enrichment plant in secret under the military government in the 1980s and declared it afterwards. The plant has been restarted and stopped repeatedly and is not operating.

Enriched uranium from this company feeds fuel fabrication, and from there 373 operating reactors across these types. Heavy water reactors are absent because they run on natural uranium and skip enrichment entirely.

| Pressurised water reactor | 309 |
| Boiling water reactor | 45 |
| Gas-cooled reactor | 9 |
| Light water graphite reactor | 7 |
| Fast reactor | 2 |

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.
