Nuclear Power 1. Background to Nuclear Power In last six years has been a remarkable renewed interest in nuclear power. Why this has happened is awareness of global warming. Lecture look at impacts of renewed interest. World has lots of energy In Lecture 3: Big Three Hydrocarbons: coal  found in many countries; cheap to use. Dirtiest of carbon fuels natural gas  lots of it but expensive Petroleum concern of peak oil - Old idea - new importance - Difficult to predict - Contributor to green house gases These hydrocarbons used primarily in specific areas Petroleum drives transportation Coal produces electricity Western economies dependent on cheap energy - demand for electricity is increasing. U.S. demand will increase by about 20% within decade. Infrastructure to maintain search engines like Google Requires 5 gigawatts of power Equivalent to 50 large power plants Note: 1/3 of power used to cool equipment 1/3 lost in transmission Geopolitical Issues

- Producing countries - Consuming countries - Threats to shipping of energy Global Warming - public acceptance very recent - in 2000 most western countries were planning a phased withdrawal of nuclear power  - too expensive; too dangerous Until that time: 1. continue with coal burning power plants with cleaner technology (such as carbon  sequestering) 2. Increase use of natural gas 3. Develop alternative energy sources - Europe, not North America Within three years - complete turn around. Phase out coal and build nuclear This would solve electricity supply. Does not consider petroleum in transportation not its role as a source of greenhouse  gases Western countries still haven't started to build. One new plant in Finland Since 2000 several plants opened in Asia. 2. Nuclear Power
