Dungeness B, a twin AGR station that last generated in September 2018, moved straight into defueling in June 2021 rather than restart. EDF is still removing fuel, and in March 2026 the ONR consulted on EDF's decommissioning scoping report; the site will later pass to the NDA.

Current state
| Status | Fuel removal |
| Country | United Kingdom |
| Location | Dungeness, Kent, England |
| Site | Dungeness |
| Units | Reactor 1, Reactor 2 |
| Unit count | 2 |
| Reactor types | AGR |
| Owner / licensee | EDF Energy |
| Strategy | Deferred (SAFSTOR) |
| Final shutdown | 2021-06 |
| Spent fuel | Defueling under way since 2021 (about 25% of one reactor's fuel removed as of December 2024). |
| Notable issue | Full site restoration expected to take nearly a century; neighbouring Magnox Dungeness A is separately decommissioned by NRS. |
Notes
final shutdown uses the June 2021 decision to end generation (last power was September 2018).
