Fuel supply exposure
The fuel families Bulgaria'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 |
|---|---|---|---|---|
| VVER (hexagonal) fuel | 2 | 2.1 | TVEL Fuel Company, Westinghouse Electric Company |
