•Level of (energy) dependence the country accepts ?
•Concern towards environmental problems ?
•Concern towards a sustainable development ?Energetic independence vs years
TECHNICALTECHNICAL
•Technologies are safe and under perfect control
New types of reactor are in project, safer, with better yields and less wastes (EPR reactor, hybrid reactors, ..)
•Better knowledge of the behaviour of wastes, both in the matrices (concrete, glass) and in the environment

ADVANTAGESADVANTAGES
• Technologies safe and under perfect control
• Uranium abundant and well distributed over the world
• No rejects of green house gases
DRAWBACKSDRAWBACKS
• Management and future of nuclear wastes
• Nuclear reactors are big installations, not suitable to be dissiminated as small units

NUCLEAR ENERGY : overall balanceNUCLEAR ENERGY : overall balance
• OBJECTIVE
- The energetic needs will increase all over the world (water purification) while a shortage of fossil energies is foreseen
- The environnemental stakes are crucial.
- Multiple and interconnected factors
- No miraculous solutions
- Major political and courageous decisions are necessary
- Most serious and worrying problem
CONCLUSIONSCONCLUSIONS
•SUBJECTIVE- Renewable energies are to be developed but they cannot face the demand in terms of quantities and of power ; energy storage is a major concern.
- Energy economies are to be encouraged at all stages and better considered in urbanism, transportation, architecture, etc… within the general concern of sustainability but they will only slow down the increase.
- Fossil energies should be kept available to specific needs and to less developed countries (humanitarian parameter)
- The development of nuclear energy appears as a necessity nowadays to face the demand but it must be kept under severe, both internal and international, control
