Dear little one,
Have you ever seen a battery that has run out of power and cannot be used anymore? Well, when a nuclear power plant is too old or cannot be used safely anymore, it is closed down and it needs to be taken apart, cleaned up, and made safe for people and the environment – just like a big battery that has stopped working.
The Nuclear Decommissioning Authority (NDA) is like a team of grown-ups who are responsible for taking care of closed nuclear power plants in the United Kingdom. They make sure that the plants are taken apart safely, the leftover radioactive materials are managed properly, and the land is cleaned up and made safe again for people and animals.
They also make sure that the people who work on decommissioning the power plants are safe and that they use special clothes, tools, and equipment to avoid any exposure to radiation.
NDA is not one person, but a big organization with many teams of scientists, engineers, and experts who work together to manage decommissioning projects across the UK. They have policies, regulations, and goals to manage the power plants and reduce any risks related to radioactive materials.
So, just like when we close down something and clean it up to make it safe, the NDA works hard to protect people and the environment from any potential dangers posed by old nuclear power plants.
I hope that makes sense, little one. Stay curious!
