Reactor safety experiments at the Marviken nuclear power station

The responce of reactor containments in severe loss-of-coolant accidents was studied in 25 non-nuclear experiments at the Marviken nuclear power station in Sweden. The experiments have demonstrated impressively the safety function and mode of action of the containment, as well as its conservative design. The experiments carried out in the original containment have shown the condensation phenomena of hot steam in cold water, already observed in model experiments, and were in good agreement with theoretical predictions.
