摘　　要：工业水平的不断发展为屏蔽装置的研发提供了技术支持,能动式和模块化已成为核电厂屏蔽装置的研发和应用趋势。根据临时屏蔽装置中屏蔽材料或物质的形态,将屏蔽装置分为“半固定型”和“流态型”两类进行介绍;对比了不同屏蔽装置的防护效果,并简要分析了防护工程构建方式对节约安装人员集体剂量的贡献。The continuous development of the industrial level has provided technical support for the development of shielding devices. Modularization and energy driven mode have become the development and application trend of shielding devices in nuclear power plants. According to the form of the shielding materials in the temporary shielding devices, this paper divides them into " semi-fixed type ” and ufluidized type". The protective effects of different shielding devices are compared, and the contribution of the construction method of protection engineering to saving the collective dose of installers is briefly analyzed.
