摘要： A method of operating a vapor generating system, including a once-through vapor generator, wherein wet vapor is generated in the upper portion of the load range and superheated vapor is generated in the lower portion of the load range is disclosed. Generated vapor is passed through an external and remote moisture separator. Superheated vapor is desuperheated by liquid injection as it passes from the vapor generator to the moisture separator.

摘要： A typical embodiment of an integral pressurized water nuclear reactor and straight-tube steam generator combination in accordance with the invention includes a generally cylindrical pressure vessel that is assembled from three segments which are bolted together at transverse joints to form a fluid and pressure tight unit that encloses the steam generator and the reactor. This novel construction permits primary to secondary coolant heat exchange and improved control rod drive mechanisms which can be exposed for full service access during reactor core refueling, maintenance and inspection.
摘要翻译： 根据本发明的整体式加压水核反应堆和直管式蒸汽发生器组合的典型实施例包括一个大致圆柱形的压力容器，该压力容器由三个部分组装，这三个部分在横向接头处螺栓固定在一起以形成流体和压力紧密的单元， 封闭蒸汽发生器和反应器。 这种新颖的结构允许主要的二次冷却剂热交换和改进的控制杆驱动机构，其可以在反应堆堆芯加油，维护和检查期间暴露于全面服务。
