1. Warm-up #1 Provide at least 2 examples of non-renewable energy resources. – Write one advantage and one disadvantage for each. Provide at least 2 examples of renewable energy resources. – Write one advantage and one disadvantage for each. Nuclear energy is a ____________ resource. – What do you predict is an advantage or disadvantage of nuclear energy?

2. Nuclear Fusion Combining 2 atoms – Some mass changed into energy – Much more energy than fission Requirements – High speed collisions – High temperatures Occurs naturally – Sun/stars Limits to use – High temperatures – No container – Requires lots of energy

3. Enormous potential Future outlook – Uses: – Power cities – Transportation – Clean water Advantages Disadvantages

4. Nuclear Fission 1 atom split into 2 – Uranium 235 + neutron – Chain reaction – Water Generate electricity Where? – Reactors – Power plants – Aircraft carriers Issues – Waste – Control

5. SKETCH A NUCLEAR POWER PLANT DIAGRAM  Put your paper in landscape positon. Put name in upper right hand corner with the date.  TITLE: “NUCLEAR POWER PLANT: FROM FISSION TO ELECTRICITY”  You will need colored pencils: black, brown, red, orange, green, blue, purple are what I used.  Follow along step-by-step instructions

6. SKETCH & COLOR SHADE

7. LABEL REACTOR STEAM TURBINE GENERATOR TRANSFORMER CONDENSER POWER LINES BOILER Control Rods Fuel Rods

8. LABEL REACTOR STEAM TURBINE GENERATOR TRANSFORMER CONDENSER POWER LINES BOILER Control Rods Fuel Rods

9. ADD RODS, WATER PIPES & POWER LINES

10. 1. REACTOR: Produces heat via fission Containment dome Control & Fuel rods 2. BOILER Creates steam Cools plant Requires lots of H 2 O 3. TURBINE Steam turns the rotor blades 4. GENERATOR Powered by the Turbine 5. ELECTRICITY Produced by generator Water cooled and reused in CONDENSER SPENT FUEL Radioactive Storage issues/ideas Nuclear Power Plant: From FISSION to ELECTRICITY

11. Radioactive generation of electricity: Can you fill in the blanks? 1. NUCLEAR FISSION = creates HEAT 2. HEAT = creates STEAM 3. STEAM = spins the TURBINE 4. TURBINE = powers the GENERATOR 5. GENERATOR = produces ELECTRICITY generator fission turbine steam electricity heat

12. Nuclear Power Plant Reactor – Containment dome – Fuel rods – Control rods – Produces heat Moderator (boiler) – Heats other water – Creates steam Turns a turbine Powers a generator – Creates electricity Cooling Towers – Water cooled and reused Spent fuel – Radioactive – Storage issues

13. Nuclear Accidents Nuclear power has been used since the 1970s Scale – 1-7 – Incidents 1-3 – Accidents 4-7 14 ever – 2 level 7 » Chernobyl – Ukraine – 1986 » Fukishima – Japan – 2011
