FC: Nuclear Energy | By: Sabrina Salehi

1: Nuclear energy is a part of energy that can be released by fusion or fission. | WHAT IS NUCLEAR ENERGY?

2: The process that powers the sun and stars is fusion

3: Fusion is... | the reaction in which two hydrogen atoms combine together/fuse to form a helium atom. While the process is happening, some of the hydrogen's mass is changed into energy. The simplest fusion reaction to occur is when combining deuterium (heavy hydrogen) with tritium (heavy heavy hydrogen) to make helium and a neutron. Deuterium is available in normal water. Tritium can be made by mixing the fusion neutron with a light metal lithium. Fusion may potentially be an unlimited energy source!


5: Fission is... | when heavy atom elements (i.e. uranium or plutonium) split to create lighter element atoms. Fission reactions happen in steps. Elements that are lighter than iron normally do not go through fission reactions because they need energy, not release energy. When atoms that are heavier than iron go through fission reactions, the energy is let out because the mass of the complete amount is less than what the starting mass was. The leftover extra mass is changed into energy.

6: WHAT IS THE DIFFERENCE BETWEEN FUSION AND FISSION? | Many people may mistaken fusion and fission for each other because of their similar processes. An easy way to remember the difference is by remembering fission as splitting and fusion as combining. Fission is when a large atom (i.e. uranium or plutonium) gets hit by a neutron to split it. Fusion is an opposite process. During the process of fusion, very small atoms (i.e. hydrogen) use a lot of pressure and heat to force them together into a larger one (i.e. helium).

8: Nuclear power plants are sort of like steam power plants that are fueled by radioactive elements (i.e. uranium). Fuels placed in a reactor allow the single atoms to split apart. This splitting process is fission. The energy is used to then heat the water until it evaporates into steam. After this, the steam pushes through turbines, which causes the coils of wire to make contact with a magnetic field. All of this will create an electric current. | How Do Nuclear Power Plants Work?

10: Darlington Nuclear Power Plant.

11: A Real Life Example of A Nuclear Power Plant | The Darlington Nuclear Power Station is on the north shore of Lake Ontario. This is in Clarington, Ontario. This power plant station consists of 4 “CANDU” nuclear reactors. The Darlington power plant provides about 20 percent of Ontario's electricity. This is enough to serve about two million people. Some say that this station is one of the most advanced nuclear generating systems in the world.

12: EXAMPLES OF NUCLEAR ENERGY | -Power Plants (I.e. Darlington & Pickering) -Submarines that function off of small nuclear reactors -Weapons (I.e. nuclear warheads) -Cancer Treatments (I.e. radiation treatment) -Food Processing (I.e. kills bacteria)

15: If any nuclear power plant or any nuclear energy accidents occur, the following impacts may be caused upon the environment

16: Short Term Effects on the Environment | There are no short term effects that impact the environment because once a threat occurs, it disturbs the environment forever.

17: Long Term Effects on the Environment | -if buried uranium gets exposed to heat=extreme world danger -mutated fish/sea-animals -radiation=cancer

18: Uranium Disposal | The uranium that needs to be disposed is buried deep into the ground. A dangerous threat may occur if the radioactive waste is ever exposed to lots of heat. If this happens, many people will get sick or die. Also, many animals and plant life will become affected.


22: Nuclear Energy Affects Humans by... | increasing the chance of getting cancer from the radioactive contact being dealt with. It also affects humans' tissues in their bodies

24: HOW DOES NUCLEAR ENERGY AFFECT WILD LIFE? | Nuclear energy can affect the wildlife by killing and creating diseases for plants. It can mutate fish and sea animals. Also, if any animals were to drink harmed water, they can become sick

26: HOW SAFE IS THE METHOD OF USING NUCLEAR ENERGY? | The method of using nuclear energy isn't quite safe. It is very dangerous and risky because of the harmful long term effects it can create on the environment. There are three main issues with nuclear energy being used; controlling the rate of reaction, managing the exposure to radioactive materials, and keeping the security of some of the materials being used.

27: Although many say this method is dangerous, there are some who believe that this method is very safe.


29: -if exposed to heat in burial sites, it will expose everyone to a major amount of radiation and will destroy many things on earth.

32: CHERNOBYL DISASTER (Chernobyl Nuclear Power Plant) | The Chernobyl disaster was when a nuclear accident happened at the Chernobyl Nuclear Power Plant in Ukraine. A fire and explosion released large amounts of radioactive waste into the environment. This spread all over Europe. This is arguably one of the worst nuclear power plant failures in history. This was classified as a level 7 on the International Nuclear Event Scale. The 2011 Fukushima Daiichi nuclear disaster in Japan was also a level 7 on the scale. The cost to try and fix this disaster ruined the Soviet economy.
