  • Transcript

    • 1. NUCLEAR POWER Then and Now
    • 2. HOW IT ALL STARTED• In the year 1896 a man named Antoine Henri Becquerel discovered radioactivity in uranium but never made much of it until Einstein came up with the theory of Relativity, he concluded that mass(matter) and energy were two forms of the same thing. Therefore if we could transform mass into energy we can liberate huge amounts of energy itself.• In 1934 Otto Hahn and Fritz Strassman had achieved the goal of splitting an atom, the discovered nuclear fission they had finally transferred mass into energy just like Einstein said it was possible to do.
    • 3. THE MANHATTAN PROJECT• When nuclear fission was discovered and the government had been informed, they created the “Manhattan project” to produce an atomic bomb the government spent more than 2 billion dollars on facilities for the project as well as scientists, engineers, laboratories and building 37 installations in 19 states including Canada. The project was top secret and remained that was till the task was completed.
    • 4. NUCLEAR BOMBS:-• Atomic bomb: works by splitting large atomic nuclei (fission) such as uranium or more usually plutonium, this releases quite a lot of energy.• Hydrogen bomb: use an atomic bomb to ignite a nuclear fusion bomb - this is fusing hydrogen Isotopes together to form helium. This releases a lot more energy, especially as the neutrons released by the fusion part of the bomb makes the fission part more efficient.
    • 5. HOW NUCLEAR BOMB WORK:-
    • 6. VIDEO OF THE FIRST ATOMIC BOMB“LITTLE BOY”
    • 7. PICTURES OF HIROSHIMA BOMB SURVIVORS
    • 8. NUCLEAR POWER IS GOOD FOR THEENVIRONMENT• Nuclear power “Clean energy”• 1) Air Emissions: Nuclear power plants do not emit carbon dioxide, sulfur dioxide, or nitrogen oxides as part of the power generation process• 2) Water Resource Use: Nuclear power plants use large quantities of water for steam production and for cooling “Renewable”• 3) It produce 10x more electricity than normal ways.
    • 9. HARMFUL WASTE OF NUCLEAR• 1) Water Discharges: Heavy metals and salts build up in the water used in all power plant systems, including nuclear ones.• 2) radioactive waste: Every 18 to 24 months, nuclear power plants must shut down to remove and replace the "spent" uranium fuel.
    • 10. HOW NUCLEAR ENERGY WORKS
