Abstract
Abstract A nuclear reactor system which includes a reactor pressure vessel having a core predominately made up of fuel elements that define coolant flow passageways within the core, is connected in primary coolant flow communication with a heat exchanger and provided with apparatus for circulating primary coolant around the exchanger to adjust the temperature to adjust the temperature of the coolant entering some of the fuel element passageways, thereby adjusting the average temperature of the coolant leaving the core.
