Okay kiddo, do you remember the tsunami that hit Japan in 2011? Yes, that's right. Well, the tsunami caused a nuclear power plant in Fukushima to have an accident. Nuclear power plants use something called radioactive materials to produce electricity. However, if these materials are not kept in the right conditions, they can be very dangerous.
The accident caused these materials to escape from the power plant and spread out into the surrounding area. It was a very big problem because these materials can hurt people and the environment. So, a cleanup had to be done to make the area safer for everyone.
Cleaning up radioactive materials is not easy, and it takes a lot of time and effort. First, crews had to remove the contaminated soil, which is the stuff that covers the ground. They put it all in special bags and took it away to a place where it could be stored safely.
Next, they had to clean up the buildings and equipment around the power plant. They used special machines and workers who had special suits to protect them from the radioactive materials.
But that wasn’t enough. They also had to deal with the water that became contaminated because it was used to cool the power plant. So, they built a lot of tanks to store the contaminated water and then filtered it to remove most of the harmful materials.
The cleanup is still happening even though it’s been a while since the accident. The good news is that many areas in Fukushima have been made safe again for people to live and work in. You see, it’s not easy, but we are taking care of the problem step by step, and we will keep doing it until everything is back to normal.
