    • A gravitational settling bed for removal of particulate impurities in a nuclear steam generator is provided to remove sludge from a bleed stream of recirculated water and to transfer the bleed stream to a low speed region in a pressure vessel. A gravitational settling bed for removal of particulate impurities in a nuclear steam generator includes a low speed region and a bleed stream transfer device. The low speed region is formed inside a recirculation type steam generator and includes a first separator deck plate(34), an upper plate(124), and a reinforcing outer circumferential ring(122). The upper plate is positioned on the first separator deck plate. The reinforcing outer circumferential ring is adjacent to the first separator deck plate and an outer circumference of the upper plate. The bleed stream transfer device transfers a bleed stream of recirculated water generated in the recirculation type steam generator.
    • 提供用于去除核蒸汽发生器中的颗粒杂质的重力沉降床以从再循环水的排放流中除去污泥并将排出流转移到压力容器中的低速区域。 用于去除核蒸汽发生器中的颗粒杂质的重力沉降床包括低速区域和排气流输送装置。 低速区域形成在再循环型蒸汽发生器内部,并且包括第一分离器甲板板(34),上板(124)和加强外周环(122)。 上板位于第一分离器板上。 加强外周环与第一分离器甲板板和上板的外周相邻。 排放流转移装置传送在再循环型蒸汽发生器中产生的再循环水的排放流。
