Nuclear power in Belgium
nuclearchain.net/countries/belgium/ · data: Global Energy Monitor (GNPT, August 2026), CC BY 4.0 · printed from the live page
Belgium operates 2 nuclear power reactors across 3 sites, with 2.2 GW of gross capacity. 6 units have been retired.
Operating fleet by type: PWR (2). Principal operators: Engie Electrabel, EDF Luminus, EDF Belgium.
Parliament voted in May 2025 to repeal the 2003 nuclear phase-out law, which had also banned new nuclear capacity. Doel 4 and Tihange 3 were already allowed to run to 2035, and the government plans to extend their licences to 2045. Policy position as read on 2026-11-03: World Nuclear Association, Nuclear Power in Belgium (page dated 2026-10-23).

Fuel supply exposure
The fuel families Belgium'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 | 2 | 2.2 | Westinghouse Electric Company, Framatome, KEPCO Nuclear Fuel, China National Nuclear Corporation, ENUSA Industrias Avanzadas, Mitsubishi Heavy Industries |
