Research on Radioactive Level Monitoring and Migration Analysis in Coal Utilization Process of Coal fired Power Plants in Shanxi Province
Given the large number of coal-fired power plants in Shanxi Province,the province is divided into three regions:northern Shanxi,southeastern Shanxi,and western Shanxi.Three coal-fired power plants that utilize local coal have been selected.Based on the characteristics of radioactive nuclides,the radioactive levels of raw coal and ash from internal combustion coal-fired power plants in different regions are monitored,including total alpha,total beta,and gamma nuclides.On the one hand,it can grasp the radioactive levels of raw coal and coal ash,and on the other hand,it can clarify the migration direction of radioactive nuclides after the combustion of raw coal.The results indicate that the radioactive levels of raw coal and coal ash in Shanxi Province are relatively low.During the combustion process of raw coal,radioactive nuclides emitting alpha,beta,and gamma rays migrate,and a large amount of nuclides deposit in the coal ash.
