Active dismantling · Germany · Immediate dismantling

Krümmel, a 1,346 MWe BWR on the Elbe that last produced power in 2009, finally received its decommissioning and dismantling permit on 20 June 2025 after a ten-year licensing process. Vattenfall has started cutting the reactor internals; the plant has been fuel-free since end-2019.
