  1. NUCLEAR POWER: SECURE ENERGY for the 21st CENTURY Mike Corradini Nuclear Engineering & Engineering Physics Nuclear Power:Villain or Victim; M.Carbon, Pebble Beach Publishers (2002) Decision-Makers’ Forum: A Unified Strategy for Nuclear Energy (2004) Non-CO2-emitting Energy Sources for the Future

  2. Need for a Unified Energy Strategy Internationally: • Population continues to increase worldwide • Energy usage growing at similar rates (1-2%/yr*) • Electrical energy usage increasing faster (>3%/yr*) Nationally: • Abundant & secure energy is critical to our future • Continued & growing concern of fossil fuel emission • Alternative energy technologies must be considered Need to ensure energy security with bipartisan initiatives and executive priority for nuclear energy *EIA (2002) Non-CO2-emitting Energy Sources for the Future

  3. SUSTAINABILITY ISSUES Conditions for Sustainability: • Acceptable area usage • Minimal by-product streams • Economically feasible technology • Large supply of the energy resource • Neither the power source itself nor the technology to exploit it can be controlled by a few nations/regions (people/countries/regions) Non-CO2-emitting Energy Sources for the Future

  8. Top 10 Nuclear Countries (1999) • U.S. nuclear electricity generation is: • as large as France and Japan (#2 and #3) combined; and • larger than the other 7 nations in the top 10 combined billion kilowatt-hours Source: IAEA Non-CO2-emitting Energy Sources for the Future

  9. Record U.S.Nuclear Electricity Production (Billions of Kilowatt-hours) Source: EIA Non-CO2-emitting Energy Sources for the Future

  10. Industry Capacity FactorContinues at Record Level 86.8% in 1999 89.6% in 2000 90.7% in 2001 91.7% in 2002 Non-CO2-emitting Energy Sources for the Future

  12. Safety of Current Nuclear Plants • There has not been a loss of life in the US due to commercial nuclear plants (TMI released a small amount of radiation) • Chernobyl accident - a terrible accident with a bad design • These plants are now closed or redesigned for operation • Russian nuclear plant operations are being assisted by IAEA • Regional deregulation of the electricity industry introduces challenges to continue & enhance the safety of nuclear plants. • - Upgrades of power plant equipment and reliable replacement schedule • - Risk-informed decision making by the industry should be cost-effective US nuclear plants are now self-insured via Price-Anderson Act and we should renew Price-Anderson legislation for long-term Non-CO2-emitting Energy Sources for the Future

  13. Nuclear Power High Level Waste (HLW) • All nuclear fuel cycle waste (except HLW) has been safely and reliably disposed through DoE and NRC regulations; milling, enrichment, fabrication by-products as LLW • Since 1982, US law ‘defines’ spent nuclear fuel as a HLW, since reprocessing has not occurred since 1976 (Japan & Europe currently reprocess spent nuclear fuel for recycle) • Spent fuel is currently stored at ~105 nuclear power plant sites (~ 2000 mt/yr; total ~50,000 mt) & is planned to be stored/buried at one site in the US (Yucca Mtn) • All nuclear electricity is taxed at 1mill/kwhre for a HLW fund (~$0.8 billion/yr; total fund ~ $20 billion) Reassert criteria, achieve licensing & begin operation of Yucca Non-CO2-emitting Energy Sources for the Future

  16. Nuclear Safety Enhanced • Current nuclear power plants have high levels of safety: i.e., reliable operation, low occupational radioactivity dose to workers and with minimal risk and health effects from severe accidents. • Future nuclear reactor systems will meet and exceed safety performance of current reactors. • Decay heat removal, minimize transients and allow time for operator actions are the keys to successful safety performance. • Advanced LWR’s will be simplified, thus more economic and continue to minimize emissions Deploy advanced light-water reactor systems (GenIII) Non-CO2-emitting Energy Sources for the Future

  26.
