Discussion on some critical issues in the emergency monitoring program of environmental radiation in nuclear power plant

As one of the supporting technical documents for the emergency plan, the emergency monitoring program for environmental radiation of nuclear power plant (NPP) is acted as a realistic guide for the emergency preparedness and response. In this paper, the critical issues in the formulation of the emergency monitoring program, including the monitoring scheme, the monitoring methodology, the capacities of facility and equipment, the monitoring response, the capacity maintainability, and the quality assurance, were analyzed and summarized. And technical suggestions for preliminary standardized specification were presented, which would provide a reference for the establishment of the emergency monitoring program for NPP and push forward the standardization progress.
