摘要/Abstract

摘要： 为克服传统临时屏蔽装置质量大、安装时间长、安装过程中人员受照剂量高等问题,基于辐射防护最优化原则,针对某核电厂不同结构的γ放射性管线热点,设计了模块化高分子基体柔性屏蔽、异型定制化及屏风式三类临时屏蔽装置。采用蒙特卡罗方法模拟,优化了各装置的屏蔽厚度设计。结果表明,在不同的应用场景下,三种屏蔽装置均表现出良好的屏蔽性能,现场实测结果进一步验证了这些装置的可靠性与安全性。本研究可为类似管线热点的屏蔽工作提供经验,并为临时屏蔽装置的优化设计提供参考。

Abstract: To overcome the problems of heavy weight, long installation time and high exposure dose during installation associated with conventional temporary shielding devices, three types of temporary shielding devices were designed based on the principle of optimization of radiation protection, targeting γ-radioactive pipeline hotspots of various configurations at a nuclear power plant. These include a modular flexible shield with a polymer matrix, a customized shielding device, and a screen-type shielding device.In this study, the Monte Carlo method was employed to simulate and achieve the optimal design of shielding thickness for each device.The results show that the three shielding devices all exhibit favorable shielding performance under different application scenarios. Field measurements further validate the reliability and safety of the shielding devices.This study can provide experience for the shielding of similar pipeline hotspots and a reference for the optimal design of temporary shielding devices.To address the drawbacks of excessive weight, lengthy installation periods and high occupational exposure doses during installation inherent to traditional temporary shielding structures, three novel temporary shielding devices are developed following radiation protection optimization principles. The devices are tailored for gamma-ray pipeline hot spots of diverse layouts in nuclear power plants, namely a polymer-matrix modular flexible shield, a special-shaped customized shielding unit and a screen-type shielding apparatus. In this work, Monte Carlo simulations are utilized to optimize the shielding thickness of each structure. The simulation results demonstrate that all three devices achieve excellent shielding effectiveness across various working conditions. On-site measurement data further verify the reliability and safety of the proposed shielding schemes. This research offers practical engineering experience for the treatment of analogous pipeline radiation hot spots and provides a reference for the optimized design of temporary radiation shielding equipment.
