The AP600 and AP1000 reactors feature an In-Containment Refueling Water Storage Tank (IRWST) positioned at the same elevation as the Reactor Pressure Vessel (RPV) hot leg nozzle. This design facilitates the collection of coolant from the sump following a postulated Loss of Coolant Accident (LOCA). Detailed mechanisms and processes for coolant collection are outlined in the referenced document, which provides essential insights into the system's operation.
