ABSTRACT
Nuclear energy is an environmentally friendly and powerful new clean energy source, and its related technologies and applications are rapidly developing around the world. However, nuclear safety is a very important issue in the process of safe use of nuclear energy. As an important tool in nuclear emergency response and rescue, radiation emergency robots play a very important role in helping rescuers to understand the accident site in advance and make scientific decisions. In this paper, the latest technologies and achievements in radiation accident emergency robots in recent years were described, including new shielding materials, radiation protection of camera elements, robotic communication, new nuclear emergency robots, parameter optimization of robotic arms, nuclear fuel assembly breakage and leakage monitoring robots, and quick-change devices for nuclear emergency handling robots.
ABSTRACT
The cold source system of a nuclear power plant, as important part of a nuclear power project, is of great significance to guarantee the safe operation of a nuclear power plant. In recent years, there have been some cases of marine organism blockage at cold source intake at coastal nuclear power plants in China, which has adversely affected the safety and economy of nuclear power plants. According to the research result of cold source safety in coastal nuclear power plants in China and in compliance with the requirements of nuclear safety regulatory control and the engineering practice experience, the causes of, and countermeasures against, marine organism blockage at cold source intake are analyzed to further improve the safety and economy of nuclear power plants.
