Abstract:
A PWR includes a secondary circuit that is normally fluidly isolated from the primary circuit. The secondary circuit includes secondary fluid in a steam generator. In response to detection of a core melt, the secondary circuit is placed in fluidic communication with the primary circuit, so that secondary fluid from the steam generator can flow into the primary circuit and then into the reactor vessel.
