“华龙一号”核电厂的辐射防护最优化设计

辐射防护最优化是核电厂辐射防护设计中的关键问题之一。本文结合国际原子能机构(IAEA)提出的辐射防护最优化设计策略,围绕核电厂辐射防护最优化设计过程中的设计目标、设计内容与评估、确保持续改进等几个方面对华龙一号核电厂的辐射防护优化设计进行了概述,对华龙一号设计中涉及的辐射源项优化、辐射分区优化、事故后辐射防护设计优化、职业照射剂量评价、环境排放设计优化等方面开展的工作进行了介绍。辐射防护最优化原则在 “华龙一号”(HPR1000)的设计工作中得到了有效的贯彻与执行。

The design of radiation protection optimization for HPR1000

Optimization of radiation protection is the key issue in the radiation protection design of Nuclear Power Plants.Based on the optimization strategy for radiation protection described in IAEA Guidance,this paper gives a brief overview of the radiation protection optimization design for HPR1000 from the aspects of optimization design strategy,design goal,design content and evaluation,and ensuring continuous improvement.The optimization design contents of HPR1000 are introduced,including source terms,radiation zone,radiation protection after accident,dose assessment.The principle of radiation protection optimization has been effectively implemented in the design of HPR1000.
