Concerns for the safety of nuclear power production were greatly increased after the Chernobyl accident in 1986 , eventually leading to plans for its phase-out in certain countries . According to German Nuclear Phase-out regulations , Isar-I was to be shut down in 2011 , with operations in Isar-II continuing until 2021 . After the March 2011 Tōhoku earthquake and tsunami in Japan , however , the decision was made to expedite shutdown . Isar-I was closed as of 17 March 2011 for a three-month moratorium on nuclear power the result of that moratorium announced in the early hours of 30 May 2011 was that Isar-I would not return . Isar-II , being one of the strongest ( ca. 1,400 MW ) and most modern reactors in Germany , is supposed to run until the end of the phase-out ( 2022 )
