Objective 3: Write the nuclear energy essay in 2 lessons. Criterion A will be used to assess this task.

Questions: 1. How nuclear energy is used to solve energy scarcity? Humans are running out of fossil fuels to make electricity, because the earth produces it slowly and naturally. Humans are using fossil fuels faster than it can be replaced. Experts say that the world's supply of petroleum could be used in decades. Some of our solution are nuclear energy, wind energy and solar energy. Wind and solar energy can't make enough for a lot of people. Nuclear energy makes a lot of nuclear waste which is bad for the environment.



2. How is nuclear energy produced?

when uranium is placed in fuel rods. The rods are placed in water tanks. When uranium is bombarded by neutrons it makes the uranium splits into groups called Krypton and Barium. When this happens it creates a chain reaction and produces a lot of heat which heats up the water and the water turns into steam. The steam allows the turbines to turn and it makes electricity.



a) What is nuclear fission? A nuclear fission is when a neutron bombards the uranium. The uranium splits apart into groups called krypton and barium. When the nuclei splits there is a lot of energy releases. Neutrons are the only atomic particles that are both easily accessible to cause a fission. Uranium can produce steady supply of energy. Every fission gives off more neutrons to bombard the uranium (this is a chain reaction)/.

b) How is nuclear energy used to generate electricity? In number 1 the uranium rods are heated up by nuclear fission which makes the water hot and into steam. In number 2 & 3 the steam activates the turbines In number 4 the turbines drive the generator that makes electricity And then they link to our homes.

3. What are the advantages, disadvantages and limitations of nuclear energy? I am making the table in pages. Generate a high amount of electrical energy in one single plant:

4. How does nuclear radiation affect the environment?

Nuclear energy doesn't use Carbon dioxide but it use's uranium.The process of finding uranium releases high amounts of carbon dioxide into the environment.

5. How does nuclear radiation affect health? Nuclear radiation affects our health by when there are small neutrons entering your body and it leaves some damaged and it can spread and take over your body. Some people's bodies are stronger than others so some might not have a bad case as others.

Nuclear Energy has it's up and downs to help reduce the use of fossil fuel.Humans are running out of fossil fuels to make electricity, because the earth produces it slowly and naturally. Humans are using fossil fuels faster than it can be replaced. Experts say that the world's supply of petroleum could be used in decades. Some of our solution are nuclear energy, wind energy and solar energy. Wind and solar energy can't make enough for a lot of people. Nuclear energy makes a lot of nuclear waste which is bad for the environment.

Nuclear Energy is produced when uranium is placed in fuel rods. The rods are placed in water tanks. When uranium is bombarded by neutrons it makes the uranium splits into groups called Krypton and Barium. When this happens it creates a chain reaction and produces a lot of heat which heats up the water and the water turns into steam. The steam allows the turbines to turn and it makes electricity. The dangerous part is that if this is not done right then a nuclear fission happens. A nuclear fission is when a neutron bombards the uranium. The uranium splits apart into groups called krypton and barium. When the nuclei splits there is a lot of energy releases. Neutrons are the only atomic particles that are both easily accessible to cause a fission. Uranium can produce steady supply of energy. Every fission gives off more neutrons to bombard the uranium (this is a chain reaction).

There are many advantages and disadvantages of using nuclear energy like that for radiation can cure cancer. Radiation can reduce the size of the tumors. People are treated by radiation oncologists. Radiation Oncologists put radioactive material in the body and it stays there for a long time and it kills the cancer cells. Nuclear energy doesn’t make carbon dioxide or sulfur dioxide. But nuclear waste remains radioactive for thousands for years. Another Advantages is that it generate a high amount of electrical energy in one single plant. The plant can make 3,942 Megawatts (MW) in 2010. A solar energy plant has 48 MW. So if there was a terrorist there would be more damage if they bombed the nuclear plant because there are more MWS. But the nuclear waste is very dangerous. And people have to look after it more many years ( 10'000 years according to USA. Environmental Protection Agency).

Radiation affects both the environment and human health. Nuclear energy doesn't use Carbon dioxide but it use's uranium.The process of finding uranium releases high amounts of carbon dioxide into the environment. Nuclear radiation affects our health by when there are small neutrons entering your body and it leaves some damaged and it can spread and take over your body. Some people's bodies are stronger than others so some might not have a bad case as others. The way we meausre radiation dosage is the rem, which stands for Roentgen Equivalent in man. It shows the amount of radiation needed to make damage of living tissue. A doese above 100 rems can cause nausea, vomiting, headache and some loss of white blood cells. Many people die from radiation,

Nuclear energy has its up and downs but we need to learn more about this so in cause if there is anything again in the world that happen to Japan we will know what yo do better next time.
