The document discusses several topics related to nuclear energy including: 1) Nuclear energy is a prominent energy source in Europe, accounting for 31% of produced electricity, and has very low greenhouse gas emissions compared to fossil fuels. 2) Safety procedures and international cooperation have improved nuclear safety significantly, with the probability of core damage decreased by a factor of 10 to 100. 3) Funds set aside during plant operation can cover decommissioning costs, which amount to only 5% of the total generation costs due to technological and financial factors.

8. Some points on Nuclear Safety New Operating Procedures and advanced HMI have improved operator response in any Plant condition, including the most severe ones International cooperation : WANO , IAEA , WENRA ensures sharing of best practices and that there are no operators or plants with sub-standard performances Over 11.000 reactor*years of Nuclear industry operating experience Operational Nuclear Safety Some principles of Nuclear Safety Culture (WANO): Everyone is personally responsible for nuclear safety Leaders demonstrates commitment to safety Trust permeates the organization Decision-making reflects safety first A questioning attitude is cultivated Nuclear safety undergoes constant examination All Nuclear Operators adhere to commitment of “ strong nuclear safety culture ” and to the personal and collective responsibility for the Nuclear safety (WANO) Technological innovation through research and engineering Significant safety enhancement of the Nuclear Plants currently under construction : probability of Core Damage Frequency – CDF – decreased by a factor of 10 to 100 Even in case of accident event, consequences are confined within the Plant boundaries and exclusion zone. Target is to have no significant effects on neighboring population and human activities. Technology

9. Some points on Nuclear Decommissioning Decommissioning funds are created during Plant operation Several NPPs have been decommissioned and brought green field : Big Rock Point, Maine Yankee, Saxton, Trojan, Yankee Rowe in USA, Greisfswald in Germany Costs are now predictable with good accuracy (350-600 €/kW, including waste disposal) Due to the financial lever and the time lag between Plant shut-down and de-commissioning phase to finance costs, decommissioning component only amounts to 5% of the nuclear generation cost Reactors currently under construction are designed also for the decommissioning phase Improved reactor design and technological development are expected to significantly lower decommissioning costs

10. Deep geological repository is the available technical solution for final disposal of HL wastes At least one repository is under construction ( Finland ) and other are under authorization or development Quantities to be disposed are small Alternative strategies are considered by the different Countries in order to take into account technological developments in the fuel cycle and NPP’s (permanent disposal, temporary storage for full recycle) Funds for final disposal of HL wastes are created during Plant operation Due to the small quantities of HL wastes, financial lever and the time lag between Plant shut-down and final disposal of HL wastes, final disposal repository only amounts to 3 % of the generation cost Radwaste for 8 billion kWh produced (1 year production of 1000 MWe NPP) (1.700.000 households): 300 m 3 of low and intermediate level waste (cube of 6.7 m side) 30 tonnes of HL solid waste (~20 m 3 ; 28 to 75 m 3 after encapsulation) If generated by fossil fuels: 1.5 billion m3 NG or 2.5 million tons of coal consumed 2.6 to 5.4 million tons of CO2 emitted Some points on Nuclear Radioactive wastes
