now highly valued generating assets Planned lifetime of about 40 years; for many plants, 50 to 60 years now expected Investment in power uprating and preparing for extended operation 15 Vendors of Nuclear Power Plants in Operation Consolidation of NPP Vendors Since 1990 17 Main Current NPP Vendors & Designs Westinghouse (AP‐1000) AREVA (EPR, Atmea) Atomenergoprom (VVER‐1200, VVER‐1000) Mitsubishi Heavy Industries (APWR, Atmea) Doosan (APR‐1400) General Electric‐Hitachi (ABWR, ESBWR) Toshiba (ABWR) Atomic Energy of Canada Ltd (ACR, Candu‐6) CNNC, China Guangdong NPC (CPR‐1000) To come: CAP‐1400 (Chinese Gen III+ design) 18 Nuclear Power Plants Under Construction Location No. of units Net capacity (MW) Argentina 1 692 Brazil 1 1 245 Bulgaria 2 1 906 China 24 25 010 Finland 1 1 600 France 1 1 600 India 4 2 506 Iran 1 915 Japan 2 2 650 Korea 5 5 560 Pakistan 1 300 Russia 11 9 153 Slovak Republic 2 782 Chinese Taipei 2 2 600 Ukraine 2 1 900 United States 1 1 165 Total 61 59 584 19 Source: IAEA PRIS Nuclear Energy Technology Roadmap Prepared jointly by the Nuclear Energy Agency and the International Energy Agency ©OECD/IEA 2010 A Series of Roadmaps Covering the main low‐carbon energy technologies Based on a scenario to halve energy‐related CO2 emissions by 2050 (near decarbonisation of electricity) Assess current status of technology and set out specific technology targets to be achieved and by when Other barriers that need to be overcome (e.g. legal, regulatory, financial, public acceptance, etc.) Policy support required for R&D and for deployment Identification of roles & responsibilities, i.e. who needs to do what and when Looks to 2050, but focus on near‐term actions and milestones (next 10 years) 21 ETP 2010 BLUE Map: Nuclear Assumes 1 200 GWe of nuclear power by 2050 (up from 370 GWe today); 610 GWe in ETP Baseline 9 600 TWh/year of electricity, 24% of global total Need to add 25 GWe/year in 2020s, rising to 40 GWe/year in 2040s Allowing for life extension and larger units, could require 20‐25 new units per year High Nuclear case has 2 000 GWe nuclear by 2050, nearly 16 000 TWh, 38% of global electricity Model shows this would be cost‐effective (against CCS), but IEA doubts feasibility 22 Electricity Production by Source in Baseline & BLUE Map Scenarios 23 Growth in Nuclear Capacity in BLUE Map Scenario 24 Nuclear Roadmap Structure Status of Nuclear Energy Today Existing fleet;

fuel cycle capacities will also need to increase A great increase in highly qualified and skilled human resources will also be needed Progress needs to be made in building and operating facilities for the disposal of spent fuel & high‐level waste Safeguards and physical protection measures must be maintained and strengthened where necessary Generation IV reactor and fuel cycle technologies may offer improved sustainability, economics, proliferation‐ resistance, safety and reliability, starting before 2050 31 Key Actions for Next 10 Years Demonstrate the ability to build the latest nuclear plant designs on time and within budget Develop the industrial capacities and skilled human resources to support sustained growth in nuclear capacity Establish the required legal frameworks and institutions in countries where these do not yet exist Encourage the participation of private sector investors in nuclear power projects Make progress in implementing plans for permanent disposal of high‐level radioactive wastes Enhance public dialogue to inform stakeholders about the role of nuclear in energy strategy Expand the supply of nuclear fuel in line with increased nuclear generating capacity 32 The Nuclear Energy Roadmap was released on 16 June 2010 All roadmaps are available at: www.iea.org/roadmaps 33.
