  Germany’s Unterweser completes removal of steam generators
  All four steam generators at Germany’s Unterweser nuclear power plant have been removed from the reactor building, plant owner PreussenElektra has announced. The single-unit pressurized water reactor was shut down in 2011 as part of Germany’s decision to phase out nuclear energy. Decommissioning and dismantlement of the reactor began soon after PreussenElektra was granted a permit for the work in February 2018.
