Nuclear reactor element
专利汇可以提供Nuclear reactor element专利检索，专利查询，专利分析的服务。并且A nuclear reactor element includes a vertically operating, elongated tubular gas-coolant duct in which a bundle of reactor rods having metal casings is positioned, the duct having an adjustable flow choke in its upper end portion above the bundle of rods and the duct having a lower portion extending below the bundle. A plurality of such elements are operated in parallel in a gas-coolant breeder reactor with the flow chokes of each individually adjusted to obtain a uniform coolant temperature discharging through their lower portions. For emergency use the element has a static non-adjustable flow choke positioned in its lower portion by material which deforms and permits this static choke to fall, if heated by coolant heated by the reactor rod casings operating at excessively high temperatures. This static flow choke is designed so that the adjustable flow choke may be adjusted to provide a coolant flow for normal operation but which would provide for a somewhat larger flow passage in the absence of the choke. Therefore, if due to abnormal operation the static choke falls, a larger coolant flow passage is immediately established without requiring adjustment of the adjustable flow choke.，下面是Nuclear reactor element专利的具体信息内容。
