RESERVKYLSYSTEM FOR VETSKEINSPRUTNING I EN TRYCKVATTENREAKTORS HERD

摘要

The pressure vessel of a reactor such as a PWR is provided with nozzles for the emergency injection of coolant into at least one water-box placed above the reactor core and rigidly fixed to the pressure vessel. Sprinkler-tubes placed within the fuel assemblies in parallel relation to the fuel pins are each connected to the water-box by means of a rectilinear tube.
