  1. NUCLEAR FUEL CYCLE PLANTS OF ENEA AND FN TO BE DECOMMISSIONED EUREX PILOT REPROCESSING PLANT (ENEA - Saluggia Center) ITREC PILOT REPROCESSING AND REFABRICATION PLANT (ENEA - Trisaia Center) FN INDUSTRIAL FUEL FABRICATION PLANT (Bosco Marengo - AL) • PLUTONIUN • PILOT FUEL FABRICATION PLANT • OPEC • POST IRRADIATION EXAMINATION FACILITY • (ENEA -Casaccia Center)

  2. ITREC: pilot reprocessing and refabrication plant (U-Th fuel cycle) (ENEA - Trisaia Centre) • Main past activities: • 1975 -1978: reprocessing of Elk River • spent fuel (U-Th) • 1983 -1990: development and testing • of centrifugal contactors • 1995 - 2000: solidification of liquid • radioactive waste • Main decommissioning milestones: • (Ministry of Industry strategic guidelines) • within 2010: management of all radioactive • waste produced during the past activities • within 2016: decontamination and dismantling • of the plant, management of the resulting • material, free release of the site • Main decommissioning issues: • solidification of U-Th highly radioactive solution (reprocessing “final product”) • dry storage of residual spent fuel in dual purpose casks • decontamination and dismantling of equipment and hot cells

  3. OPEC : post irradiation examination facility (ENEA - Casaccia Centre) • Main past activities: • 1962-1990 : post-irradiation examination • of metal uranium and uranium • oxide spent fuels (up to 2000 Ci - 74 TBq) • 1992-1998 : spent fuel scraps encapsulation, • hot cells decontamination • Main decommissioning milestones: • (Ministry of Industry strategic guidelines) • within 2010 : safe management of all radioactive • waste and nuclear material produced during • the past activities • within 2016 : decontamination and dismantling • of the plant, safe management of the resulting • material, free release of the site • Main decommissioning issues: • removal of spent fuel scraps • management of residual radioactive waste • final decontamination and dismantling

  4. PLUTONIUM: pilot fuel fabrication plant (ENEA - Casaccia Centre) • Main past activities: • 1968-1974: process development (sol-gel) • 1977-1980: fuel fabrication for AECL • Chalk River reactor • 1990-1996: liquid radioactive • waste management • Main decommissioning milestones: • (Ministry of Industry strategic guidelines) • within 2010 : management of all radioactive • waste and nuclear material produced during • the past activities • within 2016 : decontamination and dismantling • of the plant, safe management of the resulting • material, free release of the site • Main decommissioning issues: • removal of residual nuclear material • decontamination and dismantling of glove-boxes • management of residual radioactive waste

  5. EUREX: pilot reprocessing plant (ENEA - Saluggia Centre) • Main past activities: • 1970-1975 : MTR (HEU) spent fuel reprocessing • 1980-1983 : CANDU spent fuel reprocessing • 1988-1991 : Pu nitrate-oxide conversion • (via sol-gel) • Main decommissioning milestones: • (Ministry of Industry strategic guidelines) • within 2010 : safe management of all radioactive waste • produced during the past activities • within 2016 : decontamination and dismantling of the • plant, safe management of the resulting material, • free release of the site • Main decommissioning issues: • solidification of all liquid radioactive waste • dry storage of residual spent fuel in dual purpose casks • decontamination and dismantling of equipment and hot cells

  6. FN: industrial fuel fabrication plant (ENEA - Bosco Marengo) • Main past activities: • 1973-1995 : fabrication of fuel assemblies for • Italian and foreign LWR • 1996-2001 : preparatory works • for decommissioning • Main decommissioning milestones: • (Ministry of Industry strategic guidelines) • within 2004 : decontamination and dismantling • of equipment, safe management of the • resulting material • within 2011 : controlled temporary storage • "in situ" of radioactive waste, transfer to the national • repository, free release of the site • Main decommissioning issues: • residual nuclear material removal • decontamination and dismantling of equipment and buildings
