  1. Nuclear Powerand Climate Change Adriana Mugnatto-Hamu adriana@danforthgreens.ca416-273-8247 Climate Change Conference 20102010 August 14

  2. Problems Joshua highlightedwith nuclear power: • Long construction times • Declining ore grades

  3. Lifecycle CO2e of Electricity Sources g-CO2e/kWh Low Estimate High Estimate Reproduced with permission.http://stanford.edu/group/efmh/jacobson/renew_vs_nuclear.html

  4. Time Between Planning & Operation Nuclear: 10 - 19 y (life 40 y) Site permit: 3.5 - 6 y Construction permit approval and issue 2.5 - 4 y Construction time 4 - 9 years (Average today in China = 7.1 years) Hydroelectric: 8 - 16 y (life 80 y) Coal-CCS: 6 - 11 y (life 35 y) Geothermal: 3 - 6 y (life 35 y) Ethanol: 2 - 5 y (life 40 y) CSP: 2 - 5 y (life 30 y) Solar-PV: 2 - 5 y (life 30 y) Wave: 2 - 5 y (life 15 y) Tidal: 2 - 5 y (life 15 y) Wind: 2 - 5 y (life 30 y) Reproduced with permission.http://stanford.edu/group/efmh/jacobson/renew_vs_nuclear.html

  5. CO2e From Current Power Mixdue to Planning-to-Operation Delays, Relative to Wind g-CO2e/kWh Low Estimate High Estimate Reproduced with permission.http://stanford.edu/group/efmh/jacobson/renew_vs_nuclear.html

  6. Nuclear limitations for load shifting • no reactor on the planet can drop outputmore than 50% below the nominal • ability to vary outputdecreases over the fuel cycle • varying output by limiting the reaction increases risk ... • ... and decreases reactor lifespan • reducing output below the nominalfor significant amounts of timeincreases the cost of nuclear per kilowatt hour

  7. A coal plant must be running at capacity when it is replaced by a nuclear plant

  8. Nuclear reactors reduce emissions if • they replace existing reactorsat the end of their lives • or • they can be a small part of a suite of tactics to reduce many coal plants

  14. But what about… • Footprint • Transition • Reliability • Cost

  15. But what about… • Footprint • Transition • Reliability • Cost

  16. "The amounts of fuel and waste that must be dealt with at a nuclear reactor can be up to one million times smaller than the amounts of fuel and waste at an equivalent fossil-fuel power station."

  17. Area to Power 100% ofU.S. Onroad Vehicles Wind-BEV Footprint 1-2.8 km2 Turbine spacing 0.35-0.7% of US Nuclear-BEV 0.05-0.062% Footprint 33% of total; the rest is buffer Cellulosic E85 4.7-35.4% of US Geoth BEV 0.006-0.008% Solar PV-BEV 0.077-0.18% Corn E85 9.8-17.6% of US Reproduced with permission.http://stanford.edu/group/efmh/jacobson/renew_vs_nuclear.html

  20. The wind doesn't always blow and the sun doesn't always shinewhen you need them to • Nuclear output is steady

  21. Meeting peak demand • Solar power • Storage • Biofuels • Carbon capture • Hydro power • Load shifting
