Nuclear reactor - contg cure, heat exchanger primary coolant and pump within reactor vessel

摘要

A nuclear reactor is of fully integrated construction. A central column carries a bottom support plate on a centre pivot. Multiple reactor cores in precise geometric spacing are mounted on the support plate - each with a heat exchanger above. The support plate and centre column are motor driven and can rotate the cores to the fuelling facility as required. The primary coolant pump is integral with the centre column and coolant flow is directed upwards through the fuel channels. A jacking system enables the reactor core/heat exchanger to be disengaged prior to rotation.
