The context is that all german reactors that aren't experimental or soviet are decommissioned on operators money without state financing.

The example of isar is particularly interesting - isar 2 is one of the latest that started decommissioning but is in much more advanced state vs others. Each operator does it as they wish. If you wait a bit more, rad levels drop so it's easier to decommission with less specialized equipment
