    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 reactor system of a boiling water type atomic power plant including a reactor pressure vessel, a primary containment vessel containing the reactor pressure vessel, a main turbine, a main steam piping extending through the primary containment vessel between the reactor pressure vessel and the main turbine, and inside and outside main steam isolation valves provided on the main steam piping inside and outside the primary containment vessel, respectively. A closure valve is provided on the main steam piping at a position near the primary containment vessel and is adapted to quickly close in less than 3 seconds upon a break accident of the main steam piping. A volume of the reactor pressure vessel allotted for accommodating steam is correspondingly enlarged to allow the closure valve to quickly close upon a break accident of the main steam piping.

    摘要: An apparatus for mixing gaseous fuel and air for combustion, particularly premixing-type combustion in a gas turbine, has a conduit providing a passage for flow of the air with a reverse bend defined by opposed first and second wall portions that bound respectively the outside and the inside of said reverse bend as seen in a longitudinal section. The reverse bend establishes a flow region of air having a velocity gradient extending transversely across the conduit from a high velocity zone adjacent the first side wall portion at the outside of the reverse bend to a low velocity zone. Injection means for the gaseous fuel injects the fuel from the first side wall portion into the high velocity zone with a velocity component transverse to the air flow and in a direction towards the low velocity zone. Rapid and uniform mixing is obtained.
