In order to provide this proof, the Mühleberg nuclear power plant arranged for model tests to be conducted by the Swiss Federal Institute of Technology (ETH), Zurich. These tests led to the finding that in specified extreme situations, gravel movements between the Wohlensee dam and the Mühleberg nuclear power plant could result in a blockage of the special emergency system water intake. A blockage of this sort could lead to core damage in case of an extreme flood.
