Understanding nuclear

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


Brief history

Brief History

  • 1895X-ray invention by Roentgen

  • 1932Einstein, Theory of RelativityE=mC*2

  • 1942First nuclear fission by FermiCP-1

  • 1945Hiroshima/Nagasaki atomic bombs

  • 1953Eisenhawer, Atoms for Peace

  • 1956First NPPCalder Hall (UK)

  • 1957International Atomic Energy Agency

    (IAEA) created


Brief history 2

Brief History(2)

  • 1958Korea, first Atomic Energy Law

  • 1970Nuclear Nonproliferation Treaty

  • 1978Korea, first NPP Kori-1 operation

  • 1980Korea, NPP technical self-reliance

  • 1986Chernobyl accident (USSR)

  • 2005IAEA Nobel Peace Prize

  • 2009Major nuclear arms reduction


What is nuclear power

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


Nuclear power generation

Nuclear Power Generation


Nuclear fuel cycle

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)

Nuclear power world status

Nuclear Power World Status

  • 30 countries operate 439NPPs (2007)

    • 1. USA104units(19%)

    • 2. FRA59 units(77%)

    • 3. JPN55 units(28%)

    • 4. RUS31units(16%)

    • 5. ROK20units(35%)

      Nuclear electricity 15% of world total

  • New NPP constructions mainly in Asia

    • INA(6), RUS(6), CPR(5), ROK(8)


Nuclear power world prospects

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.


Nuclear power status in korea

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
