    • 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。

    • A nuclear reactor for generating electricity is disposed underground at the bottom of a vertical hole that can be drilled using conventional drilling technology. The primary coolant of the reactor core is the working fluid in a plurality of thermodynamically coupled heat pipes emplaced in the hole between the heat source at the bottom of the hole and heat exchange means near the surface of the earth. Additionally, the primary coolant (consisting of the working flud in the heat pipes in the reactor core) moderates neutrons and regulates their reactivity, thus keeping the power of the reactor substantially constant. At the end of its useful life, the reactor core may be abandoned in place. Isolation from the atmosphere in case of accident or for abandonment is provided by the operation of explosive closures and mechanical valves emplaced along the hole. This invention combines technology developed and tested for small, highly efficient, space-based nuclear electric power plants with the technology of fast-acting closure mechanisms developed and used for underground testing of nuclear weapons. This invention provides a nuclear power installation which is safe from the worst conceivable reactor accident, namely, the explosion of a nuclear weapon near the ground surface of a nuclear power reactor.
    • 用于发电的核反应堆位于可以使用常规钻井技术钻孔的垂直孔的底部的地下。 反应堆堆芯的主要冷却剂是位于孔底部的热源和靠近地球表面的热交换装置之间的孔中的多个热力学耦合的热管中的工作流体。 此外,主冷却剂(由反应堆堆芯中的热管中的工作流体组成)可缓和中子并调节其反应性,从而保持反应堆的功率基本恒定。 在其使用寿命结束时,反应堆堆芯可能被放弃到位。 在发生事故或放弃的情况下,大气中的隔离是通过沿着孔放置的爆炸封闭物和机械阀的操作提供的。 本发明结合了针对小型,高效率,基于空间的核电站开发和测试的技术,开发并用于核武器地下试验的快速闭合机制技术。 本发明提供了一种核能装置,它是从最可能想到的反应堆事故中安全的,即核动力堆反应堆地面附近的核武器爆炸。
