Pressure suppressing arrangement
Abstract
Abstract A NUCLEAR STEAM GENERATING PLANT IS DISCLOSED WHICH IS ENCLOSED WITHIN A CONTAINMENT STRUCTURE WHICH EMPLOYS THE MELTING OF A SOLID MATERIAL SUCH AS ICE FOR PRESSURE SUPPRESSION AND HEAT ABSORPTION PURPOSES. AN ANNULAR DIFFUSER SECTION IS SITUATED BENEATH AN ANNULAR SOLID MATERIAL CONTAINING COMPARTMENT TO PROHIBIT EXCESS COOLANT ESCAPING FROM THE REACTOR AFTER AN ACCIDENT FROM OVERLOADING AND CHANNELING THROUGH VERTICAL SECTIONS OF THE MELTABLE SOLID. THE DIFFUSER SECTION COMPRISES A PLURALITY OF LIQUID TRAPS WHICH ACT AS VALVES, I.E., EACH TRAP FILLS WITH LIQUID AND IS ESSENTIALLY SEALED AFTER A RATED LOAD OF ESCAPING COOLANT HAS MELTED A PORTION OF THE VERTICAL SECTION OF SOLID MATERIAL ABOVE IT TO ENSURE THE EXPOSURE OF OTHER SECTIONS OF SOLID MATERIAL TO THE ESCAPING COOLANT.
