Nuclear power station radiation distribution prediction system

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.
