    • A nuclear steam supply system utilizing gravity-driven natural circulation for primary coolant flow through a fluidly interconnected reactor vessel and a steam generating vessel. In one embodiment, the steam generating vessel includes a plurality of vertically stacked heat exchangers operable to convert a secondary coolant from a saturated liquid to superheated steam by utilizing heat gained by the primary coolant from a nuclear fuel core in the reactor vessel. The secondary coolant, may be working fluid associated with a Rankine power cycle turbine-generator set in some embodiments. The steam generating vessel and reactor vessel may each be comprised of vertically elongated shells, which in one embodiment are arranged in lateral adjacent relationship. In one embodiment, the reactor vessel and steam generating vessel are physically discrete self-supporting structures which may be physically Iocated in the same containment vessel.
    • 一种使用重力驱动的自然循环的初级冷却剂流经流体互连的反应堆容器和蒸汽发生容器的核蒸汽供应系统。 在一个实施例中,蒸汽发生容器包括多个垂直堆叠的热交换器,其可操作以通过利用来自反应堆容器中的核燃料芯的主要冷却剂所获得的热量将二次冷却剂从饱和液体转化为过热蒸汽。 在一些实施例中,二次冷却剂可以是与兰金动力循环涡轮发电机组相关联的工作流体。 蒸汽发生容器和反应堆容器可以各自包括垂直细长的外壳,在一个实施例中,它们以横向相邻的关系排列。 在一个实施例中,反应堆容器和蒸汽发生容器是物理上分离的自支撑结构,其可以物理地定位在相同的容纳容器中。
