A METHOD OF HEATING A WORKING MEDIUM IN THE HEAT EXCHANGER OF A NUCLEAR REACTOR INSTALLATION COMPRISING THE STEPS OF (1) CIRCULATING A HEAT VEHICLE THROUGH THE REACTOR AND THE HEAT EXCHANGER AT A VARIABLE RATE OF FLOW, (2) CIRCULATING A WORKING MEDIUM AT VARIABLE FLOW RATES IN A PLURALITY OF PARALLEL COMPONENT FLOWS IN HEAT EXCHANGE RELATIONSHIP WITH THE HEAT VEHICHL IN A FLOW DIRECTION OPPOSITE TO THE FLOW DIRECTION OF THE HEAT VEHICLE INTHE EXCHANGER, AND (3) DISTRIBUTING THE WORING MEDIUM BETWEEN THE PARALLEL COMPONENT FLOWS AT VARIABLE RATES IN RESPONSE TO THE RATE OF FLOW OF THE HEAT VEHICHLE TO THE NUCLEAR REACTOR TO HAVE EACH PARALLEL COMPONENT FLOW IN A HEAT EXHCANGE RELATIONSHIP WITH THE HEAT VEHICLE OF THE SAME TEMPERATURE DROP WHEREBY THE TEMPERATURE DROP IN THE HEAT VEHICLE FLOW SHIFTS TOWARD THE ENTRY THEREOF INTO THE HEAT EXCHANGER UPON REDUCTION OF FLOW RATE OF THE WORKING MEDUM AS COMPARED TO THE TEMPERATURE CURVE FOR A UNIFORM REDUCTION OF ALL THE COMPONENT FLOWS.
