    • A pressure-tube nuclear reactor can include an outer shell having an interior to contain a moderator at a first pressure and a coolant plenum to receive the coolant fluid at a second pressure, the second pressure being greater than the first pressure. The reactor also includes a plurality of pressure tubes. Each pressure tube is received within and extends through a corresponding shell tube and is configured to releasably retain at least one fuel bundle. A first end of each pressure tube being coupled to the plenum tubesheet in fluid communication with the plenum chamber and a second end of each pressure tube fluidly connected to a coolant conduit to enable the coolant fluid to flow between the coolant plenum and each pressure tube and to flow from the nuclear reactor for further processing.
    • 压力管核反应堆可以包括具有内部的外壳,所述外壳具有在第一压力下的减速器和用于在第二压力下接收冷却剂流体的冷却剂室,所述第二压力大于所述第一压力。 反应器还包括多个压力管。 每个压力管被容纳在相应的壳管内并延伸通过相应的外壳管,并被构造成可释放地保持至少一个燃料束。 每个压力管的第一端连接到与增压室流体连通的增压管板,并且每个压力管的第二端流体连接到冷却剂管道,以使得冷却剂流体能够在冷却剂室和每个压力管之间流动, 从核反应堆流出进一步处理。
