6 DD & R : Strategy Immediate and total dismantling of shutdown facility is recommended by French Safety authority, will be performed by CEA if possible/reasonable: safety control, operating, maintenance cost optimization, fall off operating staff,. Specific cases will follow deferred dismantling: short lived radio nuclides, technico economical optimum, End state : all nuclear material, wastes and dangerous substances evacuated If impossible: decommissioning with industrial or state constraints associated to localized hot spots, ICPE nucléaire. Solid and liquid waste : minimization, optimization of categorization (VLLW, LLW, LLW-LL, ILW-LL, HLW), on line evacuation Research of technico economical optimization (clean up stage, recycling, reuse, ) Pluri annual cost planning (accounting provisions, dedicated funds) 6

28 Nuclear waste Most part of waste is generated by DD & R programs Waste management costs represent ~ 30% of project cost MLAW FMA : Industrial route : CSM and CSA since beginning 90 Producers effort : no saturation, FA Pb recycling inside CEA FAVL : law : MSA standby process Perpetuate on site storages No graphite disposal. No graphite storages => Postpone D&D programs MAHAVL : DIS program & storages dimensioned using hypothesis in CIGEO commissioning in If postponed : 1. Programs continuation DIS & RCD + storages setting up? or 2. DIS & RCD programs postponed? 28
