Dynamic response of PWR vessel during a blowdown
Abstract
This paper presents a study of the behaviour of a 1300 PWR structures during the acoustical period of a blowdown accident, caused by a sudden break of the cold pipe at the outlet of the pump. The calculation gives displacements and pressures for many points of the vessel. Besides it gives the reaction forces in internal supports and also the loading level reached in the support device of the vessel.
