Transcript of Nuclear Energy

By: Kaitlyn Nuclear Energy What is Nuclear Energy? Nuclear energy is energy in the core of an atom. Atoms are tiny particles that make up every object in the universe. There is enormous energy in the ties that hold atoms together. How do you Make Nuclear Energy? Nuclear energy can be released from atoms in two ways: nuclear fusion and nuclear fission.

In nuclear fusion, energy is released when atoms are combined or fused together to form a larger atom. This is how the sun produces energy.

In nuclear fission, atoms are split apart to form smaller atoms, releasing energy. Nuclear power plants use nuclear fission to produce electricity. How do we use Nuclear Energy? Nuclear energy can be used to make electricity. The military often use nuclear reactors to power their submarines and aircraft carriers. Which Countries use Nuclear Energy? Thirteen percent of the world’s electricity comes from nuclear power plants.
Nuclear energy is being used in more than 30 countries around the world, and even powers Mars rovers. Advantages and Disadvantages History and Future of Nuclear Energy How Fission Splits the Uranium Atom The sun is basically a giant ball of hydrogen gas undergoing fusion into helium gas and giving off huge amounts of energy in the process Nuclear Powered Submarine How Nuclear Energy is Used to Make Electricity In electric power plants, the reactors supply the heat to turn water into steam, which drives the turbine-generators. The electricity is shipped through transmission lines to homes and other customers. Pickering Nuclear Power Plant Advantages No greenhouse gasses: 1 pellet of uranium produces the same amount of energy as 126 gallons of oil and it does not produce 1 ounce of CO2
Reduces dependence on foreign oils and natural gas
Although the initial cost of building nuclear plants is high, the running costs are relatively low
This technology is already available and it does not have to be developed first
It is possible to generate a high amount of electrical energy in one single plant. Disadvantages Radioactive waste: Nuclear power plants produce 2,000 metric tons of radioactive waste every year
Nuclear power plant accidents include the Chernobyl disaster (1986), Fukushima Daiichi nuclear disaster (2011), and the Three Mile Island accident (1979).
Nuclear power plants as well as nuclear waste could be preferred targets for terrorist attacks
Uranium is a rare resource, its supply is estimated to last only for the next 30 to 60 years History of Nuclear Energy in Ontario The first Canadian nuclear reactor was built in Chalk River Laboratories and in 1945.
The first part of the Pickering nuclear power plant became operational in around 1972.
The first half of the Bruce nuclear power plant became operational in around 1978.
Four nuclear reactors were built at the Darlington nuclear power plant in 1992.
More reactors were added to Pickering and Bruce in later projects Future of Nuclear Energy in Canada The Federal Budget and other recent developments appear to show greater enthusiasm for nuclear power generation at the federal level and in Ontario.
This is happening because the government is trying to find a way to reduce greenhouse gasses while keeping a reliable energy supply. History of Nuclear Energy in Other Provinces In 1971, the 250 MW Gentilly-1 reactor came into operation in Quebec.
In 1983, New Brunswick was Canada’s third province to produce electricity using nuclear energy. Thank You for Watching my Presentation Are There any Questions? Here is Where I got my Information http://www.dosomething.org/tipsandtools/11-facts-about-nuclear-energy#
