    摘要: A natural circulation boiling water reactor system using free-surface steam separation incorporates a series of tubes near the inner wall of its reaction vessel extending from a downcomer to well-above the downcomer. These tubes allow steam bubbles which would otherwise be trapped within the downcomer to escape from the recirculating water toward the steam exit of the vessel. This lowers the volume of steam in the downcomer, lowering the water velocity required to maintain a given volume of water recirculation. The reduced water velocity results in less carryunder which results in smaller voids in the reactor core. The smaller voids provide longer fuel burnups and enhance reactor stability.

    摘要: A natural circulation type boiling light-water reactor comprises a pressure vessel, a reactor core disposed within said pressure vessel to heat light water so as to generate main steam, a steam outlet provided in a wall of said pressure vessel for drawing out the main steam therethrough to supply the same to a turbine system, and a steam path along which the main steam flows from the reactor core to the steam outlet. The reactor further comprises a steam guide for prolonging the steam path and/or a radially increased chimney for reducing the velocity of the main steam flowing through the steam path. These causes radioactive isotope .sup.16 N contained in the main steam to flow within the pressure vessel for a time period exceeding its own half-life, so that the inventory of .sup.16 N in the main steam directed towards the turbine system is reduced remarkably. In consequence, shield structures for piping and turbine systems can be reduced in size and weight.

    摘要: A boiling water reactor which comprises a reactor tank and a moderator tank located inside the reactor tank has a lid with a plurality of upstanding pipes opening into steam separators. The steam separators are secured together in groups, and each group is clamped to the lid. Each steam separator has a rising tube and each unit has a bell-shaped casing common to the group and surrounding the steam separators to provide a falling surface for the water separated in the unit. Deflection caps connected together in groups corresponding to the groups of steam separators are mounted above the open tops of the steam outlet tubes of the separators.

    摘要: In a nuclear reaction which includes a reactor tank with a lid and a steam treating unit including a moderator tank lid with steam separators attached to it and a steam drying unit arranged above the lid of the moderator tank, in order to clamp the steam treating unit members are secured in the lid of the reactor tank which exert a pressure on the steam treating unit and press it against the moderator tank when the lid is applied on the reactor tank. These members may be elastically deformable beams fixed on the ends to the reactor tank lid and arranged in a polygonal formation for exerting a clamping pressure during steam treating which is greater than the forces which may arise from a normal type of accident.

    摘要: A water-separator-superheater structure includes a horizontally disposed casing having a drum-shaped configuration into which wet steam is admitted at the bottom portion of the drum. The wet steam is caused to flow upwardly at an angle through a plurality of horizontally disposed wire netting mattresses arranged in superposed stepped relation which serve to separate out the moisture which drains off through the bottom of the casing, and the dried steam then passes through a tube type superheater to a discharge outlet. The tubes of the superheater between which the dried steam passes are disposed at a steeply inclined angle in order to promote self-draining.
