Analysis of the distribution of hydrogen in the containment drywell CN Cofrentes

The development model of the containment CN Cofrentes by GOTHIC was carried out by introducing all geometric and Containment data structures, thus being able to model all the interior spaces and rooms that compose it. Thus we have obtained a detailed 3D model with sufficient accuracy to the global study of hydrogen management, allowing to take into account, when the distribution of hydrogen, both asymmetric containment as downloads mass and energy in it are made, allowing to simulate the distribution of steam and hydrogen present in the severe accident to determine the areas of greatest risk of deflagration or detonation during the evolution of the accident.
