摘　　要：介绍了压水堆核电厂辐射控制的总体思路,并根据国内外大量现场实践经验,从机组辐射源项控制、各类放射性去污技术的开发和应用、辐射屏蔽的设计和安装,以及辐射热点的去除和管理等方面提出了具体的优化及改进措施。辐射控制是一项系统工程,每一种辐射降低技术都具有其独特优势同时也有着一定的局限性,因此有必要根据机组特点,将各类技术进行策略性组合,以实现对辐射场的持续管控和综合治理。This paper introduces the general idea of reducing the radiation field in pressurized water reactor nuclear power plant.Based on a number of field practice experience at home and abroad,some specific optimization and improvement measures are put forward,from radiation source term control for reactor unit,the development and application of various radioactive decontamination technology,radiation shielding design and installation,as well as radiation hot spot removal and management.Reducing radiation field is a kind of system engineering,because each kind of radiation field reduction technology has its unique advantages but also has certain limitations.Therefore it is necessary to combine all kinds of technology strategically according to the characteristics of reactor unit,in order to achieve continuous control and comprehensive treatment of radiation field.
