  1. Current Status and Challenging Issues of Nuclear Energy in Korea Park, Yong Taek President & CEO Korea Power Engineering Company, Inc. 18th World Energy Congress October 22, 2001, Buenos Aires, Argentina

  2. Need for Nuclear Energy (1) • Nuclear Energy in Korea • Energy security • Resolution of global warming problem

  3. 2000 1978 Nuclear 7.4% Nuclear 40.9% Hydro 5.7% Coal 36.6% Coal 3.0% Oil 83.9% Hydro 2.1% Oil 8.0% Gas 12.4% Need for Nuclear Energy (2) • The Energy Security • The lack of internal energy resources • Import almost all energy resources from abroad • Diversified energy supply has increased our energy security ( Electric power generation by energy sources )

  4. Need for Nuclear Energy (3) • The Global Warming Problem • Kyoto agreement on the Climate Change Treaty • requires the reduction of Greenhouse Gas emissions • Nuclear Energy is : • a feasible solution to global warming problem • important alternative to fossil fuel

  5. Current Status of NPPs in Korea (1) RUSSIA • Location of NPPs CHINA • 16In Operation • 4under Construction • 6 Planned • SEOUL • Ulchin #1,2,3 & 4 • Ulchin #5&6 PWR • Wolsong #1,2,3&4 PHWR • Yonggwang #1,2,3&4 • Yonggwang #5&6 PWR PWR • Kori #1,2,3&4 JAPAN

  6. Current Status of NPPs in Korea (2) • Trend of Capacity Factor 100% 90% Korea 80% Japan 70% USA World 60% Year ’90 ’92 ’94 ’96 ’98 ’00 Korea 79.3 84.5 87.4 87.5 90.2 90.4 World 65.7 67.3 70.2 72.9 73.9 76.4 ( Source : Nucleonics Week )

  7. Current Status of NPPs in Korea (3) • Trend of Unplanned Outages ( No / Unit - Year ) 4 USA 3 Korea 2 1 Japan Year ’90 ’92 ’94 ’96 ’98 ’99 ’00 Korea 2.0 1.7 0.9 0.9 0.4 0.9 0.5 0.4 0.3 0.1 0.2 0.2 0.2 - Japan 2.9 2.6 2.0 1.9 1.9 1.3 - USA ( Source : IAEA Power Reactor Information System )

  8. Current Status of NPPs in Korea (4) • Long Term Power Development Plan Nuclear X 103GWh Coal Oil 500 426,769GWh Gas 384,713GWh Hydro 400 190,125 (44.5%) 329,412GWh 153,156 (39.9%) 300 266,380GWh 126,364 (38.4%) Power Generation 108,964 (40.9%) 200 (34.9%) (7.2%) (36.6%) 100 (10.8%) (8.0%) (12.4%) (1.1%) (2.1%) 0 2005 2010 2015 2000 Year

  9. Technology Development in Korea (1) • Technology Development No.of Unit 28 APR 1400 New Project Shin Kori 3,4 Plan 24 KSNP+ Shin Wolsong 1,2 Shin Kori 1,2 20 Ulchin 5,6 KSNP Series Const. Yonggwang 5,6 16 Wolsong 2,3,4 Ulchin 3,4 Yonggwang 3,4 9 Opr. Non Turnkey Ulchin 1,2 Yonggwang 1,2 Kori 3,4 3 Turnkey Wolsong 1 Kori 2 Kori 1 ’70 ’75 ’78 ’81 ’84 ’87 ’90 ’93 ’96 ’99 ’02 ’05 ’08 ’11 ’15

  10. Technology Development in Korea (2) • KSNP Development • 1,000MWe, Pressurized Water Reactor (PWR) • Design life : 40 years • Incorporated reinforced safety requirements after Three Mile Island and Chernobyl accidents • Accident probability (CDF) : 1.0 x 10-5/yr • 4 units in operation and 4 units under construction

  11. Technology Development in Korea (3) • New Design Development Program • Improved economics, safety, and operability • KSNP+ • Same type PWR plant as KSNP • Improved safety and economics • 4 units to be in operation by 2010 • Advanced Power Reactor(APR) 1400 • 1,400MWe, Pressurized Water Reactor (PWR) • Safety improved (by 50%) • More competitive than coal power • 4 units to be in operation by 2014

  12. Challenges for Future Development(1) • Safety • Waste management • Public acceptance • Economic competitiveness

  13. Challenges for Future Development(2) • Safety • Technology development & back fitting experiences • Int’l cooperation for information exchanges • Adopted PSR(Periodic Safety Review) • To improve the safety of operating plants • PSR for the 9 operating plants to be carried out by 2006.

  14. Challenges for Future Development(3) • Waste Management • Faced with difficulties due to public opposition • Wait and see the future technology innovation • Spent nuclear fuels are temporarily stored at the site. • Seriously considering the construction of a centralized interim storage facility

  15. Challenges for Future Development(4) • Public Acceptance • Essential to the role of nuclear energy for sustainable development • To obtain public supports : • Transparency should be maintained • Information on the economic & environmental benefit should be communicated

  16. Challenges for Future Development(5) • Economic Competitiveness • Very important to sustain nuclear energy Nuclear will not succeed, if not competitive • Many studies and efforts being made world-wide • Need international cooperation for technology exchange

  17. Conclusions • Public acceptance is very important • No alternative large scale non-carbon power source is available • Nuclear energy will hold a firm position as a main source of electricity generation
