The invention discloses a comprehensive monitoring system and method for nuclear power station chimney exhaust gas. The system comprises an aerosol detection subsystem, an iodine detection subsystem, a low-range inert gas detection subsystem, a high-range inert gas detection subsystem and a gas sampling subsystem. The gas sampling subsystem comprises a first gas sampling pipeline and a second gas sampling pipeline which are arranged in parallel, the aerosol detection subsystem and the iodine detection subsystem are sequentially arranged on the first gas sampling pipeline, and the low-range inert gas detection subsystem and the high-range inert gas detection subsystem are sequentially arranged on the second gas sampling pipeline. The system is reasonable in design and convenient to implement, can be effectively applied to comprehensive monitoring of the gas discharged from the chimney of the nuclear power station by combining with a monitoring method, realizes comprehensive monitoring of the activity of aerosol, iodine and inert gas, and is large in monitoring range, high in precision, good in use effect and convenient to popularize and use.
Description
technical field [0001] The invention belongs to the technical field of radiation monitoring, and in particular relates to a comprehensive monitoring system and method for gas emitted from a chimney of a nuclear power plant. Background technique [0002] In order to protect the nuclear power plant staff and public places from radioactive radiation, the nuclear power plant has set up a radiation monitoring system (hereinafter referred to as the KRT system), which is used to continuously monitor the suspended matter in the area and air of the nuclear power plant, as well as the process and discharge of the nuclear power plant. of radioactivity. [0003] The KRT system is composed of sampling system, detector, processing unit and centralized control cabinet, including dozens of measurement channels. By monitoring cooling water from the reactor, steam from the steam generator, air and aerosols in the containment, as well as air and aerosols in the control room, ventilation ducts...
