FTR: The Isar 2 plant‘s fuel rods are almost depleted. From ordering new ones to actually getting them installed takes 12-18 months. Second: Isar 2 is out of certification. Re-certifying will take another 1-2 years. Third: the 25% co-owner of Isar 2, the city of Munich, has already declared to NOT agree, as has the 75% owner, Preussen-Elektra. And finally - this would need fundamental changes in the German laws for which a majority simply doesn’t exist.
Söder is in the middle of his re-election campaign. This is just another round of his useless populism.
(I live in Munich and have been observing this whole process of shutting down nuclear since it started 23 years ago)
If you want to learn more about the history and implementation of the shutdown decision and process: https://www.base.bund.de/EN/ns/nuclear-phase-out/nuclear-pha... is a good starting point. It’s from the German Federal Office for the safety of nuclear waste.
