  2. NUCLEARPOWER OVERVIEW: • Definition • Types of nuclear reactions • First commercial application • Mechanism & Brief History • Advantages and Disadvantages • Facts of Nuclear energy

  3. NUCLEARPOWER • Nuclear energy is made in power plants by splitting of nuclei of heavy atoms, such as Uranium. • This splitting of nuclei release a very large amount of energy. DEFINITION:

  4. NUCLEARPOWER • Fission of the nuclei of some heavy elements • Power station • Marine propulsion • Fussion of the nuclei of certain light elements • Uncontrolled release of power • (Hydrogen bomb) TYPES OF NUCLEAR REACTION:

  5. NUCLEARPOWER • UK CALDER POWER STATION (1956) • Gas cooled reactor in UK • PRESSURISED WATER REACTOR IN USA FIRST COMMERCIAL APPLICATION:

  6. NUCLEARPOWER • Nuclear energy created by mechanism called reactor. • The power source is heat produced by nuclear fission chain reaction which involves an element, struck by neutron and splitting. • This results to smaller atoms, radiations and more neutrons. Again it strikes other atoms, creating chain reaction • Reactions is controlled by neutron moderators, which depending on design of reactor MECHANISM:

  8. NUCLEARPOWER • Nuclear power is both simple and complex. • Fission neutrons produce great heat. • Heat placed in water makes steam. • Steams accelerates a turbines which turn powers a generator to make ELECTRICITY. BRIEF HISTORY:

  9. NUCLEARPOWER • According to International Atomic energy Agency, there were 437 nuclear power plants. • The five countries most reliant on nuclear energy are France, Lithuania, Belgium, Slovakia and Ukarine. • India is in the 15th place of producing electricity (4,780 MW) – World production as 374, 411 MW. COUNTRIES INVOLVES IN NUCLEAR PLANTS:

  10. NUCLEARPOWER • Nuclear plants bring jobs and prosperity to a country • Its good for the economy. • Lots of energy is produced from small amount of Uranium • Does not emit carbon dioxide (Green house effect) • Little pollution. • Provides world with most of its electricity • Canada has easy access to Uranium ADVANTAGES:

  11. NUCLEARPOWER • Disposing of nuclear waste is very difficult. • Radioactive wastes takes years to be no longer hazardous • Waste to be stored very carefully for long time. • Storage is a huge problem, since it’s a radioactive. • Very expensive. • Uranium is not renewable leads to environmental problems. DISADVANTAGES:

  12. NUCLEARPOWER • Energy supply security. • Enhances technology exports. • Electricity price stability. • Intellectual capital gains. • Improved competitively and productivity. • Direct effects on resources. • Currency appreciation and enhanced economic growth. FACTS OF NUCLEAR ENERGY:
