FC: Nuclear Energy | science
3: Nuclear energy is what powers 16% of the world's energy. It generates carbon free electricity and is similar to the way fossil fuel facilities generate power. Energy releases in nuclear fissions when the nuclei of atoms are split. The main fuel in nuclear fission to give energy is uranium. Uranium nuclei can be easily split by shooting neutrons at them. Multiple neutrons are released when an uranium nucleus is split. This is called a chain reaction.

5: An atomic bomb is made up of nuclear fission which releases a great amount of energy. The nuclear force hold all the atoms together. The element used in the atomic bomb is called uranium-235 and it is hard for the nuclear force to hold it all together. It does not split, which does not make their capacity larger but does make it explode. When the uranium splits it gives off a form of energy in heat called gamma radiation. That is the most powerful form of radioactivity.
6: Nuclear energy is made up of carbon dioxide which helps the environment but high levels of carbon dioxide is emitted when they are building and running nuclear power plants and since uranium is the main fuel of nuclear energy, to get uranium you have to mine it and mining just destroys the environment. So it all comes back to this, nuclear energy helps the environment but also destroys it.
7: Nuclear power is a very dangerous method and is used in forms of weapons like the atomic bomb but not many people die while working with nuclear energy, as shown in the picture above. If you get exposed to nuclear radiation you could have nausea,vomiting,headache and some loss of white blood cells. More intense radiation could give you diseases such as leukemia (cancer of the blood), lung cancer, thyroid cancer, breast cancer, and cancers of other organs can appear due to the radiation received.
8: In the atomic bomb America used to attack Japan, when it was falling for 43 seconds, a timed mechanism started and a uranium bullet shot at a uranium target which started a nuclear chain reaction which released a great amount of energy and exploded. First there was a massive fireball 300m wide which created a huge flash. Any area of skin exposed to the flash became very hot. The fireball was 4000 degrees Celsius. It also sent out radiations such as gamma rays. Next a half a second later came a shock wave which turned everything to bits a pieces. The shock wave moved at the speed of sound. In the end the atomic bomb killed from 90,000–166,000 people and that is a real life event that happened and that is the power of nuclear energy .
10: Nuclear energy cannot be disposed or recycled. The most dangerous type of waste are nuclear fuel rods, radiation-contaminated material and uranium mill residue. One way to dispose nuclear waste is to keep it in a storage for a long time for it to become harmless, it takes 10,000 years. Another method to dispose nuclear energy is by cooling the wastes underwater for several years, sealing them in glass, and storing them concrete bunkers aboveground. In 1957, at Russia's Ural Mountains, away from Moscow, at a dump site, they buried nuclear waste and it exploded and killed dozens of people.

20: As long as I live, I'll hear waterfalls and birds and winds sing. I'll interpret the rocks, learn the language of flood, storm, and the avalanche. I'll acquaint myself with the glaciers and wild gardens, and get as near the heart of the world as I can. -John Muir
