核电厂辐射监测系统总体结构优化过程及改进方案

Overall Structure Optimization Process and Improvement Scheme of NPP Radiation Monitoring System

核电厂辐射监测系统用于对电厂工艺、流出物及工作场所的辐射监测,确保电厂的安全运行及保护工作人员和周围群众的健康。计算机技术的快速发展,为电厂辐射监测系统实现全数字化创造了条件。从岭澳核电一期、岭澳核电二期到宁德核电,电厂辐射监测系统总体结构发生了巨大的变化。本文针对核电厂辐射监测系统在优化过程中遇到的技术问题及改进方案进行分析讨论。

The radiation monitoring system of a NPP is use for its main processes,effluents and workplaces,to ensure its safe operation and protection of worker and public health. The development of computer has created a condition for realizing digitization of radiation monitoring system in NPPs. The overall structure of this system has changed dramatically,evidenced from the development of Ling ＇Ao nuclear power Phase I,II and Ningde NPP. The technical problems encountered in the optimization of nuclear power plant radiation monitoring system and the improvement scheme is analyzed and discussed.
