| Abstract: |
| The intelligent automatic monitoring system for seaborne γ radiation dose rate measurement for coastal nuclear power plant is an unattended radiation monitoring equipment， which can continuously measure the γ dose rate in seawater and air for long time and all weather operations through online networking. The gamma energy spectrum data in water is analyzed and the activity concentration is calculated， and the real time monitoring data is uploaded to the ground data service center through both the wireless communication link and Beidou short message. Normally， the system is an important supplement and improvement to the nuclear power plant supervisory monitoring system. In the case of major nuclear safety accidents or radioactive leakage， it can effectively solve the problems caused by traditional patrolling ships which the data acquisition may not be timely and continuously in addition to a high risk of personnel exposure， high cost of vessel usage with risk of radioactivity contamination， high costs for actions or operations. Under the extreme weather conditions， the unattended automatic monitoring system can provide realtime effective water and air γ dose rate measurements in addition to data of weather and seawater temperature for nuclear power plants. Thus， the system can effectively improve the monitoring capability of nuclear power plants under extreme meteorological conditions. It has certain positive significance for the overall safety and reliability of the coastal nuclear power plants． |
