PILOT REPROCESSING

AND REFABRICATION PLANT

(ENEA - Trisaia Center)

FN

INDUSTRIAL FUEL FABRICATION PLANT

(Bosco Marengo - AL)

  • PILOT FUEL FABRICATION PLANT
  • OPEC
  • POST IRRADIATION EXAMINATION FACILITY
  • (ENEA -Casaccia Center)
slide2

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
slide3

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

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

  • 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

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
