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.

Heat removal rates from containment spray droplets following a loss-of-coolant accident in a nuclear reactor have been calculated by three different droplet models: the complete mixing model, the model with internal circulation, and the rigid sphere. Irrespective of the model, the thermalization time is found to increase with increasing droplet size. It is noticed that the thermalization times predicted by the complete mixing and nonmixing models either underestimate or overestimate the value provided by the internal circulation model. It is concluded that the effect of internal circulation cannot be ignored in estimating heat removal rates from spray droplets.
