Study on Monitoring Capacity of Noble Gas for Nuclear Power Plant Effluent

The content of nuclear power plant effluent especially the radioactive noble gas for monitoring gaseous monitoring is at low levels of radioactivity. For the nuclear power plants in operation, the monitoring results are below the limit of detection almostly, the monitoring capacity would determines the discharge evaluation level of the radioactive noble gases. The present situation of radioactive noble gas monitoring and discharge evaluation for a operating nuclear power plant efflutent in China were analyzed, comparing relevant suggestions of the EU with monitoring capability of radioactive noble gases inr China, Methods to solve the problems were proposed.
