Introduction
• Decommissioning plan: contains info about inventory,
estimation of amounts of waste,…
→ strategy, total cost assessment
• Important factor : degree of activation
→ radiological characterization
• SCK•CEN, Decommissioning & Decontamination Unit
→ inventory of all metal components
→ radiological characterization of concrete structure
of cyclotron
→ decommissioning plan & safety report

1. Cyclotron
Cyclotron CGR type 520
→ polemagnet ᴓ 120 cm, 28 t
→ multiparticle :
• p+ (2,5 - 24 MeV)
• 2H (3 - 14,5 MeV)
• 3He (6 - 32 MeV)
• α (10 - 29 MeV)
Cyclotron
Mini-workshop “Radiological Characterization of Cyclotrons for Dismantling”, January 25th, 2016, BEL V, Anderlecht
→ Operational: 1977 – 2006
• 7-10h/day
• 40-45 weeks/year
→ 1977 – 1982 : 3 beamlines
→ 1982 : + 3 beamlines & hotlab
→ Used for research in
radiochemistry
