FC: NUCLEAR ENERGY
1: Nuclear energy, or nuclear power, is a source of energy that is made from a form of processed uranium. It is the source for approximately 13% of the worlds electricity.
3: Basically, humans mine uranium from the ground and form small pellets. They then take hundreds of these pellets and put them together to form rods. These rods are put together in groups of 200 or more, and then a process called "fission" occurs. A special particle called neutrons contain the characteristic to break and split uranium, and it does. Then after a bunch of rotating, boiling and condensing, water is used to cool the fuel that is made and the fuel is contained at a pressure 150 times greater than regular pressure. This creates electricity.
4: Some people say that nuclear energy as a form of electricity is both a blessing and a curse. A gram of uranium fuel pellets, which is what we get nuclear electricity from, is equivalent to about 1000 tons of coal;coal is estimated to produce about 85% of the worlds energy by 2030. This means that creating nuclear electricity requires much less natural fuels. Coal burning is one of the main contributors to global warming too, so nuclear energy does not only require less natural materials that we could possible run out of, but it is one of our only energy sources that does not kill the earth. Also, even though coal ash waste is much less then nuclear waste, coal is directly put into the environment while power plants use protectives to make sure that nothing hazardous enters the outside world. The only bad thing that can mainly come from nuclear power plants are rare explosions, which could cause the radioactive waste to enter the environment and cause many, many problems which the earth and people are usually protected from.
5: Short term effects on the environment are very severe . Nuclear accidents are basically like bombs the size of an entire city being dropped and blowing up everything in their path. Because of the chemicals and radiation, no living thing within a mile radius would be able to survive and the place where the accident occurs is untouchable for years. Long term effects are not as bad on the environment as they are on human health. The radiation levels continue to stay high and everything in a 30 miles radius( which is usually called the evacuation zone) is contaminated, preventing agriculture and any wildlife from residing there. Because it has only been a year since the latest nuclear disaster and a few decades from the one prior, no one knows what could happen to the environment affected by the nuclear explosion in the future.
7: The long term effects of nuclear disasters on human health are by far some of the worsts. Radiation, a complicated, dangerous element is basically released from nuclear power plants when these disasters occur, as well as the typical exploding buildings debris flying everywhere kind of thing. This radiation can go million of miles in all directions and affect hundreds of thousands of people. It crawls up your bodily systems and can cause things like cancer, diseases or just very negative side affects on both your body and the environment as a whole, such as infertility, anorexia, gonorrhea,bone marrow death, central nervous system death, down syndrome, acute radiation disease and many, many more. | The short term effects on humans, however, are equally as bad, because nuclear blasts release chemicals that take time to affect others. In the first few weeks of a nuclear explosion, majority of the people exposed within the first few dozen miles die of heat and extreme radiation exposure. People can also experience permanent hair loss, constant extreme blistering, inflammation of the lungs or lastly, a low sperm count or inability to produce mature eggs for at least 3 years. Others that are extremely close die from the blast itself, from flying parts of the power plant or from being in the midst of the explosion.
9: The concerns with disposing are the same with regular waste, except they have a few extra steps.Before putting the waste in landfills, they need to measure the level of radio activity. Waste on the medium and low side of radioactivity have to be stored for hours, days or even months, until the radioactivity has completely dispersed. Waste with high levels of radioactivity have to be stored for decades or even centuries before the radioactivity is gone. After the nuclear waste is rid of all radioactivity, chemicals and anything else that could contaminate the earth, it is put in landfills just like regular waste. | To assure that no waste enters the environment, waste is stored in something called "deep burial". These are caverns that are 1000-3000 feet deep. This is the first and foremost technique used for nuclear waste disposal. Another, less used and frowned upon way that is one of the main contribution to fights against nuclear electricity is space disposal.
10: I believe that this method cam be both extremely safe and extremely dangerous. What makes it safe is the amount of precautions taken when it is in use. Nuclear reactors are located in areas where if an accident occurred, it would do as little damage to people as possible. Also, there are more things protecting nuclear reactors than probably all electricity creators combined. The only dangerous things are the radiation and chemicals inside the reactors that could be a danger to the people working near and inside it. Though they wear a lot of protection and are extremely careful, everything around them is still dangerous and could kill them on the spot. The method itself though is safe since it really only contains water, steam and natural fuels, as well as forms of condensing, boiling and pressurizing.
13: With over 50 instant deaths and over 4000 people affected by cancer, the Chernobyl nuclear incident was by far one of the worst nuclear disasters in the entire world. It all started April 26th 1986. The Chernobyl nuclear power plant had overheated and had had an internal meltdown, resulting in an explosion. Everyone within a mile radius, including the people within the power plant had died from the explosion itself or from extreme radiation exposure. But this is only where the story of the radiation dispersion begins. To this day, the amount of radiation released from the power plant puzzles nuclear energy scientists all over the world. The radiation had spread all over Europe, with over 300, 000 people being evacuated from Ukraine, Belarus and Russia. Because the radiation had spread so far, hundreds of thousands of people have been diagnosed with cancer, down syndrome, acute radiation syndrome. Because so many people have been affected, their children have been too, resulting in birth defects and a slight increase in the mortality rate. Because of the Chernobyl Nuclear Disaster -There has been a 2% increase in cancer rates -There has been an increase in DNA mutations. -More than 428,000 Ukrainian children suffer from health problems. -There has been an increase in thyroid cancer rate -Russia had a debt of over 18 billion rubles, or over 500 million Canadian dollars
