    摘要： 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 located in the same containment vessel.

    摘要： This invention relates to steam generators, and more particularly to horizontal steam generators for nuclear power plants with a water-water energetic reactor (VVER). We claim a horizontal nuclear power plant steam generator comprising a cylindrical vessel, two elliptical bottoms, at least one feed water supply and steam removal connection pipe, an inlet header and an outlet header, a heat-exchange tube bundle connected to the same, wherein number Ntb of heat-exchange tubes in the bundle is selected depending on outer diameter dtb of the heat exchange tubes as follows:
    if dtb ≤ 14 mm: 1.944 ⋅ 10 6 π 4 ⋅ dtb 5 + 0.8 2 ≤ Ntb ≤ 1.211 ⋅ 10 6 π ⋅ dtb
    if dtb > 14 mm: 1.944 ⋅ 10 6 π 4 ⋅ dtb 5 + 0.8 2 ≤ Ntb ≤ 1.111 ⋅ 10 7 π ⋅ 4 ⋅ dtb 5 + 0.2 2 and the gap between the adjacent heat-exchange tubes in the vertical direction does not exceed the vertical spacing between the heat-exchange tubes in the bundle.
    The technical result of the invention is an increased heat transfer efficiency in the steam generator with a limited number and maximum length of heat exchange tubes, which allows to use tubes employed in the industry.
