Abstract

The invention is applied to the technical field of nuclear power and provides a nuclear power station radiation distribution prediction system. The nuclear power station radiation distribution prediction system comprises multiple sensor nodes, a gateway, a server base station and remote monitoring processing centers. The multiple sensor nodes gather acquired data to the server base station through the gateway, the server base station transmits the data to the remote monitoring processing centers, and the remote monitoring processing centers predict radiation distribution of a nuclear power station according to the data, wherein the prediction includes windless condition prediction on a nuclear radiation concentration C of time t with a space coordinate position (x,y,z) on the basis of an expression shown in the descriptions, P0 is a concentration of a radioactive gas leaked at a space coordinate origin when t=0, k is a diffusion coefficient, and m is the mass of the radioactive gas in a volume V. According to the invention, the prediction accuracy is effectively improved.

Description

technical field [0001] The invention belongs to the technical field of nuclear power, in particular to a prediction system for radiation distribution of nuclear power plants. Background technique [0002] Nuclear emergency preparedness and response is an effective measure to control and mitigate possible personal injury, property loss and environmental damage caused by nuclear radiation accidents, and is also an important means to effectively deal with nuclear terrorist attacks and ensure public safety. Therefore, it is necessary to establish a highly reliable Nuclear safety monitoring and nuclear radiation distribution prediction system to ensure nuclear safety. At present, in my country's nuclear power plants, the environmental gamma radiation continuous monitoring system is composed of a few fixed monitoring stations, which are distributed within ten kilometers around the nuclear power plant to continuously monitor the gamma radiation in the surrounding atmospheric enviro...
