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?

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

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

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

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

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

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

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

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