核电站主控室通风系统应急新风管线
摘要：
本发明涉及一种核电站主控室通风系统应急新风管线的结构设计。该应急新风管线包括设在核电站厂房屋顶不同位置的两个事故取风口，两个事故取风口分别通过隔离阀进行开启或关闭；所述的两个事故取风口之间通过风管连接，并共用同一条应急送风管线与应急事故风机相连，应急事故风机将室外新风引入主控室，应急送风管线上设有碘吸附器；所述的两个事故取风口的位置相对于反应堆安全壳呈相反方向布置。本发明降低了事故工况下主控室可居留性丧失的风险，提高了主控室通风系统的可靠性，安全性。
摘要（英）：

The invention relates to structural design of an emergency fresh air pipeline of a ventilation system of a main control room of a nuclear power station. The emergency fresh air pipeline comprises two accident air taking ports at different positions of a plant roof of the nuclear power station, and the two accident air taking ports are opened or closed through isolating valves respectively; the two accident air taking ports are connected by an air pipe and share one identical emergency air sending pipeline and are connected with an emergency accident air blower, the emergency accident air blower introduces fresh air from the outdoor into the main control room, and an iodine absorption device is arranged on the emergency air sending pipeline; and the two accident air taking ports are arranged in opposite directions relative to a reactor containment. The emergency fresh air pipeline disclosed by the invention reduces the risk of losing habitability of the main control room under the working condition of the accident, and improves the reliability and safety of the ventilation system of the main control room.
