BC: The environmental impact of Nuclear energy

FC: The environmental impact of Nuclear energy | By: Peggy

2: What is Nuclear energy? | Nuclear energy comes from power plants that helps produce electricity to our homes. The power plant uses steam to generate like a fossil fuel power plant. The only difference is that they use different methods to heat the water to make steam. In a nuclear power plant, they use uranium to take place of oil, coal or gas for the fuel to heat and produce steam. They both use turbines to generate electricity though.

4: How does Nuclear Energy work? | The workers split the uranium atoms into smaller particles and that causes a large amount of heat to be produced. This process is called the fission process. A reactor controls this and the core of it holds the uranium fuel. | The uranium are made into pellets and they would look like this.

5: The fission process takes place in the reactor core, which are controlled by control rods. They are specially made with materials that help absorb neutrons so it can control the fission process. The most important part of a nuclear plant is the reactor core. As a result, it is lined with steel and has walls several feet thick. This helps to protect whatever is inside and prevents disturbance from outside. | These are control rods at a nuclear reactor.

6: Juragua Nuclear Power Plant | The Juragua power plant was the name of a power plant in Cuba. This included two nuclear power reactors. It was powered by pressurized water reactors. Inside of that, it had two turbines that had thermal powered stored. It was also designed as a domed shaped structure because if there were to be any accidents, radioactive particles would not escape as easily.

7: All these pictures are the nuclear power plant in Cuba.

8: As seen on the map, the nuclear explosion happened around that area in Japan.

9: What are the short -term effects? | The explosion had many effects and some of them were short -term effects. The short -term effects are death. Many have died instantly. Families who have lived near the nuclear power plant have had injuries.

10: Japan | March 11 | What are the long -term effects? | The long -term effects of the nuclear explosions were that people who have not have injuries might have cancer later on in the future. The reason behind this is because of the contaminated food and water that came from the explosion. Studies also show that diseases like leukemia may occur but it would not be immediate and would start later on as a long term effect. | This is what happened to many elders and children fewer than 18. They got cancer from the radioactive power that was released.

11: Cancer may also occur in this area of the human body. These tragic things happen to innocent people who have nothing to do with the power plant.

12: How does this affect wildlife and people? | Diesel generators are used and when they are started, they make plumes of black smoke. This is also another cause of global warming that impacts the environment. Every power plant uses thermal discharge and to reduce the amount of leakage, the people are only allowed to release less than 400 gallons a day.

13: All nuclear power have an effect on living things. It can give damage and can be big or small. | These effects can happen anytime and anywhere.

14: Is this method safe? | People working at the power plant have always said that it would be safe enough to live near it. Accidents can happen but they have many ways to prevent them from happening. For example, the walls of the nuclear plant are made of hard material and are several feet thick. There are back up technologies in case the power goes out. There are also scientists that check regularly on the reactor core and if something is wrong, they can detect it. They find ways to prevent it from harming the environment.

15: What concerns are there with disposing? | One of the main concerns of disposing the nuclear waste is that it is not recyclable and that it is constantly going to the environment. One option that the people have thought of is storing it in a facility so it can decay without any disturbance. The only problem would be that it would take decades for it to decay and 10,000 years for it to become harmless to the environment and any living thing. | Right now, they store waste underwater cooling them for a few years and then seal it with glass. Lastly, they store them in concrete bunkers above ground.

16: To prevent the release of radioactivity uranium is made into pellets to seal in the material. The core is protected with 400 -ton steel. Even with all these safety precautions, a disaster happened that caused an explosion. | What happened in Japan Mar. 11, 2011? | On March 11, 2011, an earthquake and tsunami had hit Northern Japan. Three nuclear power plants had meltdowns when the earthquake had knocked all the power out. That had led to disabling the backup generators that kept the cooling systems working. That had also led to explosions that created radioactive gases to be released. 80,000 people living around the plant were made to leave and by July, more than 22,000 people died.

17: These were the explosions that happened in Japan.

18: "The entire ocean of Japan is affected by a nuclear explosion. | The nuclear power plant experienced a meltdown. | Also, many people have died in the tunnel when the explosion happened.
