REVIVAL OF NUCLEAR ENERGY OPTION:  Jasmina Vujic Professor and Chair Department of Nuclear Engineering University of California, Berkeley The IEEE Oakland East Bay Chapters of Power Engineering Society and Nuclear Plasma Society and the Association of Energy Engineers (AEE) Berkeley, CA March 28, 2006 REVIVAL OF NUCLEAR ENERGY OPTION ACKNOWLEDGMENT:  ACKNOWLEDGMENT I would like to thank my colleagues for their suggestions and help with this presentations: Professor Per Peterson, Department of Nuclear Engineering John Kotek, Idaho National Laboratory Andrew D. Paterson, Environmental Business International SUSTAINABLE SOCIETY of the 21th Century?:  SUSTAINABLE SOCIETY of the 21th Century? We cannot have SUSTAINABLE SOCIETY without SUSTANIABLE ENERGY which is based on SUSTAINABLE NUCLEAR ENERGY! We need Nuclear Energy - to provide an abundant, reliable, affordable, clean, and secure source of energy for our nation and the world. Definition of SUSTAINABLE ENERGY: “A living harmony between the equitable availability of energy services to all people and the preservation of the earth for future generations.” MIT “Sustainable Energy - Choosing Among Options” Slide4:  Climate change due to natural causes (solar variations, volcanoes, etc.) Can we predict? Slide5:  Concentration of Greenhouse gases Slide6:  Greenland is melting Life-cycle analysis considers construction as well as fuel consumption:  Life-cycle analysis considers construction as well as fuel consumption Where does U.S. electricity comes from?:  Where does U.S. electricity comes from?

Why Is Nuclear Energy Important? :  Why Is Nuclear Energy Important? Nuclear energy enables: Air quality improvement Carbon emission reduction Waste reduction Proliferation risk reduction Increased energy security and independence Nuclear energy is affordable Currently operating U.S. nuclear power plants have achieved low operating costs and are attractive in today’s market We are designing new plants that can be built faster and at less cost than today’s reactors (less than $1500/kW) Source: Central Research Institute of Electric Power Industry, Japan 2000 Real Cost of Power Sources Affected by Capacity Factor :  Real Cost of Power Sources Affected by Capacity Factor Fuel costs, weather affect downtime of some sources, which impacts investment. Source: NETL, EPRI Example: An installed KW of wind is not the same as in installed KW of baseload coal and nuclear, which run many more hours regardless of weather. So, the cost per KWe must be adjusted for average capacity factor: red bar is “Effective Capacity”, adjusted for downtime.
