Due to the impact of natural factors such as earthquakes and tsunamis, a large amount of radioactive material leaked out because of chemical explosion in the Fukushima nuclear power plant.The nuclear leakage has reached the level of Chernobyl accident, and the level of Fukushima nuclear accident is seven. There are no casualties but nearly 100 cancer patients, causing a lot of economic losses. This accident also slowed down the development of nuclear power all over the world.
In this lecture, secondly, we will talk about the earthquake and tsunami to understand the Fukushima nuclear leakage, and learn the layout of the Fukushima nuclear power plant and the design of the primary circuit structure of the boiling water reactor. Then introduce the detailed process of this accident and compare this accident with TMI and Chernobyl. Finally, the impact of the nuclear leakage on the surrounding areas and the development of international nuclear energy is described.
