Nuclear Power as a Basis for Future Electricity Generation in the World Professor Igor Pioro Faculty of Energy Systems & Nuclear Science University of Ontario Institute of Technology Canada [email protected] 1 Sources for Electrical Energy Generation It is well known that the electrical power generation is the key industry for advances in any other industries, agriculture and level of living. In general, electrical energy can be produced by: 1) non-renewable sources such as coal, natural gas, oil, and nuclear; and 2) renewable sources such as hydro, wind, solar, biomass, geothermal and marine. However, the main sources for electrical-energy production are: 1) thermal - primary coal and secondary natural gas; 2) nuclear and 3) hydro. The rest of the sources might have visible impact just in some countries. In addition, the renewable sources such as wind and solar are not really reliable sources for industrial power generation, because they depend on Mother nature plus relative costs of electrical energy generated by these and some other renewable sources with exception of large hydro-electric power plants can be significantly higher than those generated by non- renewable sources. 2 Electrical energy consumption per capita in selected countries No. Country Watts per person Year HDI* (2010) 1 Norway 2812 2005 1 (very high) 2 Finland 1918 2005 16 (very high) 3 Canada 1910 2005 8 (very high) 4 USA 1460 2011 4 (very high) 5 Japan 868 2005 11 (very high) 6 France 851 2005 14 (very high) 7 Germany 822 2009 10 (very high) 8 Russia 785 2010 65 ( high) 9 European Union 700 2005 - 10 Italy 603 2005 23 (very high) 11 Ukraine 446 2005 69 ( high) 12 China 364 2009 89 ( medium) 13 India 51 2005 119 ( medium) * HDI – Human Development Index by United Nations; The HDI is a comparative measure of life expectancy, literacy, education and standards for living worldwide. It is used to distinguish whether the country is a developed, a developing or an under-developed country, and also to measure the impact of economic policies on quality of life. Countries fall into four broad human development categories, each of which comprises ~42 3 countries: Very high – 42 countries; high – 43; medium – 42; and low – 42.

The plant equipped with 550 MWel × 10 coal- fired steam generators‒turbines + 70 MWel × 4 gas-fired steam generators‒turbines and is the world's largest emitter of carbon dioxide with over 40 million tons per year (Source: Wikipedia). 7 Genesee Power Plant (Alberta, Canada) (EPCOR coal-fired power plant) Three generating units: • Units G1 & G2 – each 381 MW net/410 MW gross (built in 1989 and 1994, respectively) • Unit G3 (the only one in Canada supercritical-pressure coal-fired power plant) – 450 MWel net/490 MWel gross, i.e., internal needs are 40 MWel or 8.2% from gross ($695 M unit recently completed in 2005). Operating design parameters for G3: • Typical net annual production – 3,745 GWh. • Requires 1.8 million t of coal annually, therefore, large surface mine adjacent to plant. • Ash production ~41 tonnes per hour = ~360,000 tonnes annually. • (for comparison: Fuel load into: 1300-MWel PWR – 115 t (3.2% enrichment); 1330- MWel BWR – 170 t (1.9% enrichment)). G3 Supercritical Boiler Technology • Furnace temperatures of supercritical-pressure boiler reaches 1,400°C. • G3 boiler produces steam at 26 MPa - ~50% higher than G1 & G2. Hitachi turbine information: 495 MW, TCDF-40, 3600 rpm, steam primary: 24.1 MPa & 566/566°C (reheat) Genesee Cooling Pond • Artificial pond covering 735 hectares (1 hectare 100 m × 100 m) = 7.35 km2. • Contains 34 million m3 of water. • Can provide cooling water for up to four 400-MWel units (1,600 MWel combined). • Water level in pond maintained by pumping water from North Saskatchewan River.
