摘要：1,093,725. Cooling reactors. EUROPEAN ATOMIC ENERGY COMMUNITY(EURATOM). March 15, 1965 [March 16, 1964; Jan. 29, 1965], No. 10876/65. Heading G6C.In a heavy water moderated reactor, the fuel elements are separated from the water bya sheath and a concentric outer pressure tube. A liquid organic coolant flows inside thesheath and the fuel element. The annular zone between the sheath and pressure tube isoccupied by both gas and coolant fluid. The gas is dissolved in the coolant and releasedunder the thermal conditions existing in the zone between the pressure tube and sheath.In one embodiment, to facilitate the gas release in this zone, the sheath is provided withholes spaced regularly along its length. A flow of coolant from the interior of the sheathtakes place and a mixture of gas and fluid is formed within the zone, the speed of flow ofwhich is limited by internal restrictions. In a further embodiment, the annular zone has aseparate supply of coolant saturated with an inert gas.
