1,047,179. Cooling reactors. EUROPEAN ATOMIC ENERGY COMMUNITY (EURATOM). April 10, 1964 [April 11, 1963], No. 14971/64. Heading G6C. In an organic liquid cooled, heavy water moderated, nuclear reactor, the coolant passes down each pressure tube over the fuel elements and leaves through a Venturi type nozzle; a reduction of coolant pressure is produced at the outlet proportional to the flow rate and this maintains the pressure at the outlets of all the pressure tubes at the same value so maintaining the free level of the coolant at a selected value. Thermal insulation between the pressure tubes and the associated colardria channels is effected by a gas atmosphere. Coolant penetrates partially into the gas space and the gas rests above the free surface. The atmospheres in all the channels are connected to a common external gas reservoir.
