This Week in Brief
• 한 . 중 . 일 , FTA 영토전쟁 치열– 주력 수출상품 유사 : 가전 , 자동차 , 선박 , 철강등– 기존 한 : 8 건 45 개국 , 일 : 22 개국 , 중 : 19 개국– 한 .EU, 한 . 미 FTA 비준 지연
• 원전 방사선 위험도 국민인식 과잉반응– 자연 , 의료 방사능 보다 미소– 사고 시 사망확률 자동차의 1/100, 화재 1/40– 수명단축 효과 : 흡연 , 과체중 보다 미소

Mega scale
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
• 1895 X-ray invention by Roentgen• 1932 Einstein, Theory of Relativity E=mC*2• 1942 First nuclear fission by Fermi CP-1• 1945 Hiroshima/Nagasaki atomic bombs• 1953 Eisenhawer, Atoms for Peace • 1956 First NPP Calder Hall (UK)• 1957 International Atomic Energy Agency
(IAEA) created
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 Korean NPP export to UAE
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 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
• 30 countries operate 439 NPPs (2010)– 1. USA 104 units (20%)– 2. FRA 58 units (75%)– 3. JPN 54 units (29%)– 4. RUS 32 units (18%)– 5. ROK 20 units (35%)Nuclear electricity 14% of world total
• New NPP constructions mainly in Asia– INA(24), RUS(12), CPR(63), ROK(11)
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: UAE Gulf Countries, TUR, BYE, KAZ,
VIE, etc.
Nuclear Power Status in Korea• 21 units in operation, 7 units under construction
– Kori, Wolsung, Ulchin, Yonggwang– Localization rate 85% in design, manufacturing, const.– Long term supply contract for uranium fuel
• Base load production, nuclear share 35%– Midnight electricity rate– Radwaste disposal site (Gyeongju)
• National infrastructure well developed– High quality, low cost electricity (2% of GDP)– Essential element of the high-tech economy

Great Nuclear Dilemma
• Risk of nuclear power overwhelming– Anti-nuclear sentiment– Nuclear renaissance ??, higher cost
• No viable alternate source of energy• Economy, carbon-free, 준국산에너지
- 2011: 21 NPPs, 34% electricity- 2030: 40 NPPs, 59%
• Korean PWR technology, proven safety- Emerging export market after UAE
맺는 말• 일본 원전 사고
– accident anyplace, accident everyplace
• 한국형 경수로 기술자립의 의미– 준국산 에너지 , 고부가가치 수출산업– UAE BNPP 건설로 국제경쟁력 실증 – 先 기술 , 後 협력 / 경쟁 - Nuclear Silk Road
• 안전성 강화 국제협력 방안– 중국 원자력 안전문화 정착 기회– 한중일 3 국 원자력 협력체제 구상 (NGO)
• ‘ 그래도 원자력이다’ - 긍지와 반성 , 위기는 기회
