Simulation Research On Radioactive Gas Transfer Of Reactor

In this thesis, the transfer of radioactive gas released from PWR during normal operation is simulated, and the radioactive gas dose is also calculated in real time. It is significant for assessing the radioactivity level and ensuring the resident and environment safety around the nuclear power station.At first the thesis introduce the transfer process of the radioactive gas in PWR and relative equipment. On the basis of the radioactivity calculation method for the loop of PWR, the simulation model is set up for the transfer process of radioactive gas. Then the simulation program is compiled and debugged on platform ASCA, and the simulation result is also analyzed.The result of study shows that simulation model set up on the simulation platform can factually simulate the radioactive gas dose released from the reactor during normal operation.
