摘　　要：基于概率论和确定论分析方法建立了事故工况下场内工作人员辐射剂量控制的体系。针对典型三代压水堆核电厂,建立了事故工况下场内工作人员辐射风险分析的方法论,并采用典型事故进行验证。验证结果表明,对于选取的堆外放射性系统相关典型事故,建立的辐射风险控制体系和分析方法可很好地评估并控制事故工况下场内工作人员的辐射风险。该方法可进一步扩展至堆芯相关事故以及其他堆外放射性系统相关事故,从而提升压水堆核电厂辐射防护最优化水平。Based on deterministic and probability method,the occupational radiation dose control targets under accident conditions are established.According to the design of typical third generation pressurized water nuclear power plant,a method for analyzing the radiation risk of workers under accident conditions was established and verified by typical accidents.The verification results show that the established radiological risk control targets and analysis method can evaluate and control the radiological risk of the workers under the selected typical accident conditions related to the radioactive system outside the reactor core effectively.The established method can be further extended to accidents related to reactor core and other radioactive systems,thus improving the ALARP level of radiation protection for PWR nuclear power plant.
