Fuel supply exposure
The fuel families Spain'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 |
|---|---|---|---|---|
| PWR (square-lattice) fuel | 6 | 6.3 | Westinghouse Electric Company, Framatome, KEPCO Nuclear Fuel, China National Nuclear Corporation, ENUSA Industrias Avanzadas, Mitsubishi Heavy Industries | |
| BWR fuel | 1 | 1.1 | Global Nuclear Fuel, Westinghouse Electric Company, Framatome |
