摘　　要：从辐射源项调查分析、源项控制和辐射防护最优化支持系统等方面,介绍了田湾核电厂VVER机组降低辐射源项对工作人员集体剂量的具体控制措施。分析表明,通过对核电厂机组大修期间系统地开展辐射指数测量、辐射源项监测和数据分析、剂量评估,了解主要放射性核素产生途径,从而有针对性地优化工艺过程和关键作业方案,能够有效控制与减少辐射源项的产生,达到降低工作人员集体剂量的目的。This paper introduces the specific measures to reduce the collective dose of VVER unit of Tianwan nuclear power plant,from the aspects including radiation source investigation and analysis,source control and optimal support system for radiation protection.It demonstrates that during the overhaul of nuclear power plant,we can understand the main radionuclide production way by systematically carrying out the radiation index measurement,radiation source monitoring and data analysis,dose assessment.Thus we can optimize the process and key operation scheme,effectively control and reduce the radiation source,and achieve the target of reducing the staff collective dose.
