Abstract

Nuclear energy, classified as a clean energy source, enjoys extensive application in numerous countries worldwide. In recent years, the growth rate of marine organisms has accelerated, resulting in the formation of large aggregations of marine organisms and other large congregations that have the potential to obstruct the cold source water intake system of nuclear power plants. The safety situation about the cold source is of significant concern. This paper presents a summary of water intake safety events at nuclear power plants around the world in recent years. It also analyzes the current status of comprehensive prevention and control technology for disaster-causing floating bodies at nuclear power plants’ water intakes. The analysis is based on the latest developments in global nuclear power technology. This study provides a comprehensive overview of the advancements in fine offshore monitoring and early warning systems, passive interception techniques for open channel dredging, the evolution of active defense measures, the development of composite water intake open channel structures, bubble curtain interception methods, cutting and grinding techniques, and the subsequent transportation of marine organisms. Nevertheless, shortcomings remain in the water intake safety of nuclear power plants. These include an inadequate design basis for water intake open channels and sewage interception networks, as well as deficiencies in marine organism early warning and monitoring equipment and layout. Furthermore, the issue of sea ice represents a novel challenge confronting the nuclear power industry in coastal regions situated at high latitudes. Therefore, it is essential to undertake research and implement improvements to the comprehensive technology used to prevent and control water intake safety in nuclear power plants. It is imperative to provide robust backing for the long-term advancement of nuclear power technology.
核电站进水口致灾浮体综合防治技术发展现状综述
核能作为一种清洁能源,在世界许多国家得到了广泛的应用。近年来,海洋生物的生长速度加快,形成了大型海洋生物群落和其他大型群落,有可能阻碍核电站冷源取水系统。冷源的安全状况是一个值得关注的问题。本文对近年来发生在世界各地的核电站取水安全事件进行了总结。分析了核电站进水口致灾浮体综合防治技术的现状。该分析基于全球核电技术的最新发展。本研究全面概述了精细近海监测和预警系统的进展、明渠疏浚的被动拦截技术、主动防御措施的演变、复合进水口明渠结构的发展、气泡幕拦截方法、切割和研磨技术以及随后的海洋生物运输。然而,核电站的进水安全仍存在不足。这些问题包括取水、明渠和污水截流网的设计基础不足,以及海洋生物早期预警和监测设备和布局的不足。此外,海冰问题是高纬度沿海地区核动力工业面临的一个新挑战。因此,有必要对核电站进水安全综合防治技术进行研究和改进。为核电技术的长期发展提供强有力的支持是当务之急。

期刊介绍: Annals of Nuclear Energy provides an international medium for the communication of original research, ideas and developments in all areas of the field of nuclear energy science and technology. Its scope embraces nuclear fuel reserves, fuel cycles and cost, materials, processing, system and component technology (fission only), design and optimization, direct conversion of nuclear energy sources, environmental control, reactor physics, heat transfer and fluid dynamics, structural analysis, fuel management, future developments, nuclear fuel and safety, nuclear aerosol, neutron physics, computer technology (both software and hardware), risk assessment, radioactive waste disposal and reactor thermal hydraulics. Papers submitted to Annals need to demonstrate a clear link to nuclear power generation/nuclear engineering. Papers which deal with pure nuclear physics, pure health physics, imaging, or attenuation and shielding properties of concretes and various geological materials are not within the scope of the journal. Also, papers that deal with policy or economics are not within the scope of the journal.
