Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of environmental pollution monitoring, in particular to a nuclear power plant environmental anomaly monitoring device. BACKGROUND

[0002] The nuclear power plant does not produce PM2.5 or PM10 under stable operation conditions, and does not produce toxic gases such as chlorine, ammonia and phosgene, and belongs to low-carbon and environmentally friendly clean energy. The nuclear power plant needs to use a small amount of toxic gases such as chlorine, ammonia and phosgene under special conditions. The nuclear power plant will emit a small amount of gaseous radionuclides under accident conditions.

[0003] In order to protect the public and regulate environmental pollution monitoring, the nuclear power plant is generally designed with online monitoring facilities for toxic gases and gaseous dust. The monitoring elements include environmental temperature and humidity, wind speed, wind direction, chlorine, ammonia, phosgene, PM2.5, PM10, environmental radiation dose rate, aerosol and iodine sampler, etc. Among them, the nuclear facility ventilation tower outlet is also designed with multiple real-time monitoring instruments for environmental radiation dose rate.

[0004] The Tianwan nuclear power plant is located in the Lianyun district of Lianyungang city in Jiangsu province, but the northern part of the Tianwan nuclear power plant base is adjacent to the iron ore bulk cargo operation area of Lianyungang port and the national petrochemical storage base, and the southern part borders the Lianyungang Xuwei petrochemical base and the cargo terminal. These petrochemical bases and cargo terminals are the main sources of chlorine, ammonia, phosgene, PM2.5 and PM10.

[0005] How to accurately measure the environmental pollution of the nuclear power plant, how to correctly identify the source of the pollution, and how to start the emergency environmental pollution response to ensure that the production process of the nuclear power plant meets the environmental requirements and the expectations of the public has always been the focus of research by the environmental emergency department of the nuclear power plant. The current scheme has the following problems:

[0006] 1. Although the environmental monitoring station inside the nuclear power plant is designed with pollution monitoring equipment for chlorine, ammonia, phosgene, PM2.5 and PM10, the environmental pollution monitoring data from the environmental pollution monitoring equipment of a single environmental monitoring station cannot accurately locate the source direction of the pollution, nor can it rule out the possibility of self-emission pollution.

[0007] 2. When the environmental monitoring station alarms, manual confirmation and judgment of the pollution level and the source of the pollution is time-consuming and labor-intensive, the response is lagging, and personnel must be on duty on site. SUMMARY
