2. Hydropower Quiz: Label and write out the function of the missing parts Name:___________

3. Nuclear Power (AKA Atomic Power) Where does it come from: Heat which converts water to steam. Steam is then used to drive the turbines which drives the generator. Electric energy comes the. The heat comes from the energy of the radioactive decay of uranium. (From Science 10) Summarize: Radioactive decay  Heat produces  Steam spins  Turbine spins produces heat steam turbine generator

4. Nuclear Power (AKA Atomic Power) Where does it come from: Heat and electric energy comes from the nuclear energy harnessed during the radioactive decay of uranium. (From Science 10) Summarize: Radioactive decay  Heat produces  Steam spins  Turbine spins produces heat steam turbine generator Ways nuclear power is used: -Warfare (Nuclear bomb) -Power plants for household and industrial energy -On ships, submarines and other isolated areas (Icebreakers) -Possible uses in space exploration in the future

5. Who Uses it? Mainly used: US, Europe (France), India, East Asia (10% of the worlds energy)

6. Lifecycle Lifecycle of Nuclear Power: 1)Mining uranium 2)Uranium ore is compacted and stablized into a form called yellowcake

7. Lifecycle Lifecycle of Nuclear Power: 1)Mining uranium 2)Uranium ore is compacted and stablized into a form called yellowcake 3)Yellow cake is safer to transport then ore 4)Yellowcake must be converted to Uranium hexafluoride

8. Lifecycle Lifecycle of Nuclear Power: 1)Mining uranium 2)Uranium ore is compacted and stablized into a form called yellowcake 3)Yellow cake is safer to transport then ore 4)Yellowcake must be converted to Uranium hexafluoride 5)This form of uranium is used to generate power 6)After 6 years the uranium must be placed into a waste system for 5 years and then into long term radioactive waste storage

11. Nuclear Power Plant N

12. Parts of the Nuclear Power Plant

13. Pros Produces no emissions

14. Pros Produces no emissions: – Smoke leaving the stacks is actually water vapor There is a large supply of uranium available

15. Cons Uranium is only useful for 6 years Must be stored for long period of time – 5 years pool storage (too hot for dry storage) – Long term dry storage Nuclear disasters: -Chernobyl (1986) -Fukushima (2011)

16. Cons Nuclear Explosions Three nuclear explosions Chernobyl disasterChernobyl disaster (1986), Fukushima Daiichi nuclear disasterFukushima Daiichi nuclear disaster (2011) Three Mile Island accidentThree Mile Island accident (1979) Waste products – Toxic (radioactive) – Breakdown slowly – Need to be secured

17. Assignment Nuclear Disaster Research Next class: Cons of nuclear power Zero Hour: Disaster at Chernobyl (Discovery Channel) (2004)
