Nuclear power

  1. 1.  Nuclear Fission is the process of splitting a atom’s nucleus by bombarding it with neutrons.
  2. 2.  This creates large quantities of energy which is carried by water to run turbine (similar to wind turbine) which turn produced electricity and connected to the grid. The notorious Uranium-235 needed for fusion. Every fission can produce 200 times more energy than the same amount of TNT.
  3. 3.  Carbon-free. So better than fossil fuels.  Cheap source of electricity  Most powerful energy source  Much more efficient than wind power.  New fusion will produce no waste at all.
  4. 4.  Radioactive waste can last for ages (thousands of years). These are mutagens meaning they can alter the DNA killing cells or giving cancer.  High security risk. Can be under terrorist threats.  Non-Renewable. Once used…that’s it.  System will fail if not looked after.
  5. 5.  We are growing up in an age where the word ‘nuclear’ or ‘Uranium’ makes an image of a giant explosion and green toxic waste, that is not it. It could be a way to reduce Global Warming.
  6. 6.  After being removed from the reactor, the waste is put into steel cylinder.  These are so strong they can withstand 50 mph crashes.  Then they are emptied into landfill. America sends their waste into a tunnel on a side of a mountain. They are able to store more.
  7. 7.  In 26th April 1986, a event in Ukraine left the world stunted. It was the largest nuclear catastrophe the world had ever seen. On the site, 2 workers were killed and many more firemen trying to fight the blaze. The government death toll was around 200 but many say it was much more. So what went wrong? Chernobyl Nuclear Disaster
  8. 8. On that day, tests were being carried out on the reactor and the amount of pressure it could handle. However, it was a soviet reactor and many assessments were different to the American ones. The bad care meant a graphite top which was not strong even broke open shooting the radioactive waste into the open air. Some were carried over by the wind to Russia and Europe.
  9. 9. This diagram shows the movement of the radioactive material. This was caesium-137 with iodine and barium. They are toxic as well and kill plants and just by inhaling it.The material half-live is 30 years which means they can last for 60 years which is a massive threat.
  10. 10.  This picture shows a deformed child when the mother was pregnant. They were not alone many lost their arm, legs and dysfunctional organs. It is predicted to take decade for the generation to recover.
  11. 11.  People thought nuclear power was at a end but new regulations mean chances of such devastations are at a minimum.  But it should be a lesson of what a beast nuclear energy can be if not treated well.  I am for nuclear power, because it is cleaner than fossil fuel and more efficient than wind and solar.  And yes it caused havoc in 1986, but we had problems from oil and gas as well such as the BP oil spill.  Accidents will happen. All we can do is reduce the chances of it.
