Transcript of Nuclear Energy
Energy released by a nuclear reaction The Process Nuclear power plants use uranium, which is mined, processed, and then concentrated into fuel rods.
When the uranium atoms in the fuel rods are hit by other extremely tiny particles, they split apart. The number of tiny particles allowed to hit the fuel rods needs to be controlled, or they would cause a dangerous explosion.
The energy from a nuclear power plant heats water, which creates steam and causes a turbine to spin.
The spinning turbine turns a generator, which in turn produces electricity. The Formula Interesting Facts Nuclear power plants provide France with almost 80% of its electricity.
Many countries around the world use nuclear energy as a source of electricity. In the United States, a little less than 20% of electricity comes from nuclear energy.
The Fukushima Daiichi nuclear disaster is a series of equipment failures, nuclear meltdowns, and releases of radioactive materials at the Fukushima I Nuclear Power Plant, following the Thoku earthquake and tsunami on 11 March 2011.
Fission of an atom of uranium produces 10 million times the energy produced by the combustion of an atom of carbon from coal.
Around 6% of the world’s energy and 14% of the world’s electricity is produced by nuclear power. There are over 400 nuclear power reactors in use around the world.
Nuclear energy comes from mass-to-energy conversions that occur in the splitting of atoms. Albert Einstein’s famous mathematical formula E = mc2 explains this. The equation says: E [energy] equals m [mass] times c2 [c stands for the speed or velocity of light]. This means that it is mass multiplied by the square of the velocity of light.
In 1938, two German scientists, Otto Hahn and Fritz Strassman and physicist Lise Meitner of Austria, discovered that they could split the nucleus of a uranium atom by bombarding it with neutrons. As the uranium nucleus split, some of its mass was converted to heat energy. Advantages Disadvantages Bibliography Further Studies High School Courses Nuclear Energy and Science 10 THANK
YOU When the nucleus of an atom is split, it releases a huge amount of energy called nuclear energy. When struck by a tiny particle, Uranium-235 breaks apart and releases energy. Nuclear Energy: How It Works Videos Sustainable Energy Choices for the 21st Century In nuclear fission, atoms are split apart to form smaller atoms, releasing energy. Nuclear power plants use nuclear fission to produce electricity. Science 10

Chemical Engineering Nuclear power can come from the fission of uranium, plutonium or thorium or the fusion of hydrogen into helium. Today it is almost all uranium. Uranium plays a very important role in the production of energy through nuclear power.
Uranium is a silvery-white metallic chemical element in the actinide series of the periodic table, with symbol U and atomic number 92. A uranium atom has 92 protons and 92 electrons, of which 6 are valence electrons. Career Nuclear engineers:
develop and work with the technology that allows us to harness electrical power from nuclear reactions.
Some design power plants and equipment that transforms nuclear reactions into electricity
Many work in power plants, monitoring equipment and overseeing maintenance and repairs
Others work with nuclear fuels, ensuring they are produced, used, and disposed of safely
Some work in health care, designing diagnostic equipment such as x-ray machines
Earnings: $45,000 to $200,000 a year or more
Educations and training:
A bachelor’s degree in nuclear engineering or a related subject
A master’s degree or PhD is often required for senior and advanced research positions
Register as a Professional Engineer (P.Eng) Natural uranium has three isotopes: uranium-238, uranium-235, and uranium-234. Uranium isotopes are radioactive. The nuclei of radioactive elements are unstable,meaning they are transformed into other elements. Radioactive decay results in the emission of alpha or beta particles from the nucleus. The equation for nuclear fission: Nuclear energy is a clean, safe way to make electricity. It does not burn any fuel like coal so there are no pollutants released into the air. Lower carbon dioxide (and other greenhouse gases) released into the atmosphere in power generation.
Low operating costs .
Large power-generating capacity able to meet industrial and city needs
Existing and future nuclear waste can be reduced through waste recycling and reprocessing, similar to Japan and the EU The energy source for nuclear energy is Uranium. Uranium is a scarce resource, its supply is estimated to last only for the next 30 to 60 years depending on the actual demand.
Nuclear creates radioactive waste, even when fuel is recycled.
Working in a nuclear power plant can be dangerous for the health of the workers. Working in these types of plants has been connected to cancer and to high levels of radiation within the body. This topic relates to various chapters and concepts we covered in the science 10 course.
Mainly the unit 2, Chemical Reactions and Radioactivity, goes in depth and explains what nuclear energy is. Also gives us a better understanding of how it is formed and all the information associated with nuclear energy is included. Science 10 introduced the study of atoms which apply to nuclear energy because Uranium is a source of nuclear energy.
This topic relates to radioactivity because the daughter products are radioactive and are a significant waste disposal problem.
Science 10 includes a detailed study of the nuclear reactions, such as fission. This relates to the project because nuclear fission of uranium is the source of energy for all nuclear power generation used today.
CANDU reactors are also mentioned in the textbook and relate to nuclear energy because the CANDU ("Canada Deuterium Uranium") reactor is a Canadian-invented, pressurized heavy water reactor that produces nuclear power from nuclear fuel.

http://www.kids.esdb.bg/uranium.html I chose this topic because I wanted to explore a different method for producing power. I was interested in finding out a ''green'' energy source that will be less harmful to our environment. Also after learning some brief information on nuclear energy in class, I was interested in finding more information about the whole process. Nuclear energy has been one of the most controversial topics, therefore I wanted to learn about its pros and cons in depth. Vocabulary words associated with science 10 are in green Whys does Nuclear Energy concern us? Canada's energy sources We all use power in our daily lives, therefore everyone should be aware of all the power sources available.
We should consider this cheap, clean source of power that does not use fossil fuels or add greenhouse gases to the atmosphere because important energy sources such as crude oil, natural gas and coal will not last forever.
In Canada, hydro and nuclear are important sources of electricity, primary energy use continues to be dominated by fossil fuels, for transportation, heating and in industrial processes. Therefore nuclear energy should be used more often to decrease global warming.
As the human population increases, so does the demand for more energy. Nuclear energy has large power generating capacity to meet our needs. By: Jaspreet Kandola
