Nuclear Power:Our Misunderstood Friend
OverviewGrowing Demand for EnergyComparison of Nuclear with Other Forms of EnergyDisposal of WasteSafety of Nuclear Energy
Growing Demand for ElectricitySteady increase in demandImpact of electric drive vehicles on demandImpact of EGU MACT legislation on demand
Chevy VoltCan drive 35 miles before gasoline engine starts
Takes 10 hours to charge on a 120 volt line
Takes 4 hours to charge on a 240 volt line
EGU MACT legislation:Could close 20-30% of plants
Nuclear as compared with other technologies:How does it stack up?
WindBetter for the environment because it is renewableGenerates at a capacity of 20-40%Rate of Injury of Workers
SolarBetter for the environment because it is renewableCan only generate at a capacity of 20-40%Battery technology9
Nuclear vs. CoalNuclearAbout 19% of electricity generated by DTERadioactive wasteLess than 0.00001% fuel of coalHigh energy contentLess susceptible to fluctuationHigh initial cost
Coal80% of electricity generated by DTEEmissionsMining, transport, burningLow energy contentLarge fluctuations in cost of fuelHigh cost lies in fuel

*CCGT is a type of coal powered plant
Nuclear Power in France75% electricity from nuclear17% electricity from recycled nuclear powerGenerate 3 billion euro annually by selling to the rest of Europe

Chernobyl
What HappenedFailed ExperimentIgnored WarningsExplosionRunaway Nuclear Reactor
Effects of Chernobyl100,000 km2 of contaminationRise in Thyroid CancerTreatment 96% Effective.Could have been prevented.Liquidators and Acute Radiation SicknessFirefighters in the Plant.Cancer Rates in Highly Contaminated Group4000 Extra Cancer Deaths among 600,000 People.Cancer Rates of People in Contaminated Zones5000 Extra Cancer Deaths among 5 Million People

3 Mile Island
EffectsAverage Dose of Radiation1 millirem1/6th radiation produced by a chest x-rayMaximum Dose of RadiationLess than 100 milliremBackground Radiation 100 to 125 millirems per yearRadioactive IsotopesVery Low Levels DetectedRadiation ContainedContainment vessel was not breached
AftermathNRC given more control of power plantsHuman ErrorOperator training improved by lessons learned.2 Full Time inspectors at each site.Design ProblemsImproved controls and indicators.Piping system revamped.Component FailuresAuxiliary Coolant Systems.Automatic Shutdown.
