Fuel supply exposure
The fuel families Argentina's operating reactors take, and the fabricators our sources document as able to make each. This is capability, not contracts: it does not say who actually supplies a given plant.
| Fuel family | Units | GW gross | Documented fabricators | Note |
|---|---|---|---|---|
| CANDU / PHWR bundles | 3 | 1.8 | Cameco Corporation, BWX Technologies, Nuclear Power Corporation of India, KEPCO Nuclear Fuel, China North Nuclear Fuel Company |
