A PROCESS FOR REGULATING THE TEMPERATURE IN REACTORS BY INDIRECT HEAT EXCHANGE WITH PRESSURIZED WATER WHICH COMPRISES: CIRCULATING WATER FROM A FULL STORAGE VESSEL THROUGH THE EXTERNAL JACKET OF A REACTOR AND BACK TO SAID STORAGE VESSEL; HEATING AND COOLING SAID WATER TO A DESIRED TEMPERATURE WITHIN SAID STORAGE VESSEL; MAINTAINING A PRESSURE IN SAID STORAGE VESSEL WHICH IS HIGHER THAN THE SATURATION VAPOR PRESSURE CORRESPONDING TO THE MAXIMUM ATTAINABLE TEMPERATURE OF THE WATER IN THE CIRCULATING SYSTEM, SAID PRESSURE BEING MAINTAINED BY FORCING A GAS CUSHION INTO AN AUXILIARY VESSEL WHICH IS PARTIALLY FILLED WITH WATER, SAID AUXILIARY VESSEL BEING ARRANGED ABOVE SAID STORAGE VESSEL AND BEING CONNECTED TO THE HIGHEST POINT OF SAID STORAGE VESSEL BY A NARROW CONDUIT, SAID NARROW CONDUIT BEING SUCH THAT THE WATER PASSING FROM SAID STORAGE VESSEL THROUGH SAID REACTOR JACKET DOES NOT CIRCULATE THROUGH SAID AUXILIARY VESSEL; AND MAINTAINING THE WATER IN SAID AUXILIARY VESSEL AT A TEMPERATURE LOWER THAN THE TEMPERATURE OF THE WATER IN SAID STORAGE VESSEL.
