  1. Korea & the World (8)Nuclear Power for Alternate Energy 2010. 4. 27 bkkim9@gmail.com 김 병 구

  2. This Week in Brief • 4월22일 지구의 날, 전국 ‘불 끄기’ 행사 성황 • 세계 농업식량 안보기금 출범 • 10억$ 기금, 한국 5천만$ 출연 • 미 GM사 파산 1년 만에 구제금융 조기상환 • 러 흑해 함대 우크라이나 주둔 기간 연장 • 한.중, 한.터키 FTA 협상 본격화 • 태국 반정부 시위 격화

  3. Energy Alternatives • PositiveNegative Wind Carbon free, fuelLow density, unsteady Tide Carbon free, fuel Site, economy Solar Carbon free, fuel Low density, economy NuclearCarbon free, economy Radwaste,proliferation Mega scale

  4. Understanding Nuclear • Double faces of the atom • Military: Hiroshima/Nagasaki, NK • Peaceful: nuclear power, medical, agriculture, etc. • Electricity from nuclear power plants • Single largest peaceful application • 440 NPPs in operation worldwide today • Only 30 countries with high-tech infrastructure • Delivering ~ 17% of world’s electricity

  5. Brief History • 1895 X-ray invention by Roentgen • 1932 Einstein, Theory of RelativityE=mC*2 • 1942 First nuclear fission by FermiCP-1 • 1945 Hiroshima/Nagasaki atomic bombs • 1953 Eisenhawer, Atoms for Peace • 1956 First NPPCalder Hall (UK) • 1957 International Atomic Energy Agency (IAEA) created

  6. Brief History(2) • 1958 Korea, first Atomic Energy Law • 1970 Nuclear Nonproliferation Treaty • 1978 Korea, first NPP Kori-1 operation • 1980 Korea, NPP technical self-reliance • 1986 Chernobyl accident (USSR) • 2005 IAEA Nobel Peace Prize • 2009 Major nuclear arms reduction

  7. What is Nuclear Power? • Turbine/generator by heat from uranium • Burn uranium fuel instead of fossil fuel • Energy density 1,000,000 times higher than fossil • Fuel cost only 20% of total generation cost • Nuclear fuel fabrication: high-tech, precision • Reactor manufacture: high pressure/temp • Safety philosophy: multiple redundancy • Waste disposal: small volume, toxic, long-term storage

  8. Nuclear Power Generation

  9. Nuclear Fuel Cycle? • Uranium ore refined– yellow cake • Uranium conversion, enrichment– 2% ~ 4% low enriched uranium (LEU) • Nuclear fuel burns in reactor (~ 3 years) • Spent nuclear fuel contains plutonium • Radwaste treatment and disposal • Named after the new solar stars Uranus (천왕성), Pluto(명왕성)

  10. The Nuclear Fuel Cycle - Closed Conversion Mining Enrichment Uranium Fuel fabrication Plutonium Waste Reprocessing Nuclear Power Plant

  11. Nuclear Power World Status • 30 countries operate 439NPPs (2007) • 1. USA 104units(19%) • 2. FRA 59 units(77%) • 3. JPN 55 units(28%) • 4. RUS 31units(16%) • 5. ROK 20units(35%) Nuclear electricity 15% of world total • New NPP constructions mainly in Asia • INA(6), RUS(6), CPR(5), ROK(8)

  12. Nuclear Power World Prospects • Nuclear renaissance in 40 years • Proven record of economy and safety • Climate change, low carbon green growth • Energy security from oil, natural gas • Double the NPP capacity by 2030 • Existing: life extension, new NPPs • New comers: Gulf Countries, TUR, BYE, KAZ, VIE, etc.

  13. Nuclear Power Status in Korea • 20 units in operation, 8 units under construction • Kori, Wolsung, Ulchin, Yonggwang • Localization rate85% in design, manufacturing, const. • Long term supply contract for uranium fuel • Base load production, nuclear share35% • Midnight electricity rate • Radwaste disposal site(Gyungju) • National infrastructure well developed • High quality, low cost electricity(2% of GDP) • Essential element of the high-tech economy
