摘要： A control rod guide frame comprises a self supporting stack of two or more columnar elements defining a central passage. The columnar elements may include mating features that mate at abutments between adjacent columnar elements of the stack. The control rod guide frame is suitably used in conjunction with a control rod drive mechanism (CRDM) operatively connected with at least one control rod, and a nuclear reactor core, in which the CRDM moves the at least one control rod into and out of the nuclear reactor core under guidance of the control rod guide frame. In another embodiment, a control rod guide frame comprises a stack of two or more columnar elements defining a central passage having a constant cross-section as a function of position along the central passage. In another embodiment, a control rod guide frame comprises an extruded columnar element providing continuous control rod guidance.

摘要： A pressurized water reactor (PWR) includes a vertical cylindrical pressure vessel having a lower portion containing a nuclear reactor core and a vessel head defining an internal pressurizer. A reactor coolant pump (RCP) mounted on the vessel head includes an impeller inside the pressure vessel, a pump motor outside the pressure vessel, and a vertical drive shaft connecting the motor and impeller. The drive shaft does not pass through the internal pressurizer. A central riser may be disposed concentrically inside the pressure vessel, and the RCP impels primary coolant downward into a downcomer annulus between the central riser and the pressure vessel. A steam generator may be disposed in the downcomer annulus and spaced apart from with the impeller by an outlet plenum. A manway may access the outlet plenum so tube plugging can be performed on the steam generator via access through the manway without removing the RCP.
摘要翻译：压水反应堆（PWR）包括垂直圆柱形压力容器，其具有包含核反应堆芯的下部和限定内部加压器的容器头。安装在容器头上的反应堆冷却剂泵（RCP）包括压力容器内的叶轮，压力容器外部的泵马达和连接马达和叶轮的垂直驱动轴。驱动轴不通过内部加压器。中心提升管可以同心地设置在压力容器内，并且RCP将主冷却剂向下推入中央提升管和压力容器之间的降液管环形空间。蒸汽发生器可以设置在降液管环中并且通过出口增压室与叶轮间隔开。通风道可以进入出风口，因此可以在蒸汽发生器上通过通道进行管堵塞，而不需要拆卸RCP。
