摘要

PPROBLEM TO BE SOLVED: To operate stably in all patterns of operation by reducing the physical quantities of ventilation and air-conditioning installations for a turbine building in a nuclear power plant adopting a boiling water reactor. PSOLUTION: In the ventilation and air-conditioning installations which has a structure where air is introduced from the outdoors of the turbine building 1 into a space 25 on an operation floor where a turbine 2 and a generator are installed by opening louvers 5a and 5b, the atmosphere in the space 25 on the operation floor is exhausted to the outdoors of the turbine building 1 by exhaust fans 6a, 6b and 6c, outside air is supplied by air blowers 16a, 16b and 16c for the ventilation below the operation floor and the atmosphere below it is exhausted from an exhaust stack 23 through a filter 20 by air-exhaust ventilators 22a, 22b and 22c, a duct 19 which partially exhausts the atmosphere in the space 25 on the operation floor from the exhaust stack 23 by the air-exhaust ventilators 22a, 22b and 22c that exhausts the whole turbine building 1 through the filter 20 during normal operation, under abnormal conditions and during periodical inspections is placed.

要解决的问题：通过减少采用沸水反应堆的核电站涡轮机建筑物的通风和空调设施的物理量，可以在所有运行模式下稳定运行。

解决方案：在通风和空调设备中，其结构是将空气从涡轮机房1的室外引入到操作地板上的空间25中，通过打开百叶窗5a来安装涡轮机2和发电机。在图5和图5b中，操作层的空间25中的大气通过排气风扇6a，6b和6c被排放到涡轮机建筑物1的室外，外部空气由鼓风机16a，16b和16c供给以用于在操作下方进行通风。地板和其下方的大气通过排气通风机22a，22b和22c通过过滤器20从排气烟囱23排出，管道19通过以下方式从排气烟囱23部分排出操作地板上空间25中的大气：在正常运转中，在异常条件下以及在定期检查期间，通过过滤器20排出整个涡轮机建筑物1的排气通风机22a，22b和22c被放置。
