核电站取水口海生物驱赶消杀技术研究

近年来,国内多座滨海核电站海生物频繁入侵,可能引发冷源取水口堵塞、核电站跳堆事故,严重影响核电站的安全可靠运行。本文对国内外核电站冷源防护技术进行了广泛调研,介绍了多种海生物驱赶消杀技术,分析了各种技术的作用原理,论述了各种技术的优缺点,给出了工程指导建议。结合核电站取水口立体纵深防护原则,提出了一种海生物驱赶消杀综合系统模型,为核电站改造以及新建核电站规划设计提供了参考。

Research on Marine Organism Expulsion and Elimination Nearby Water Intakes of Nuclear Power Plants

In recent years, multiple coastal nuclear power plants in China have been frequently invaded by marine organisms, which may lead to the blockage of cold water intak ing and the accident of the reactor of nuclear power plant jumping off, seriously affecting the safe and reliable operation of nuclear power plants. Cold source protection technology in plant at home and abroad is researched extensivly in this thesis. It introduces the various expulsion and elimination technologies of marine organism and analyzes the principle of different type of technologies. This paper discusses the advantages and disadvantages of various technologies, and engineering guidance advice is given. Based on the principle of three-dimensional deep protection of water intake of nuclear power plant, a comprehensive system model of marine organism expulsion and elimination is proposed, which provides a reference for the reconstruction of nuclear power plant and the planning and design of nuclear power plants.
