The radiological conditions at the end of operation can be predicted based on the planned phases of operation and transition phases between them, the expected distribution of activated materials and their dose rates as well as the amounts of bulk Be and dust, and tritium distribution around the plant. Actual operation will of course lead to somewhat different conditions, but the present decommissioning plans are indicative of what will be required.

Summary of ITER Decommissioning Phases

Phase	Activity	Description	Duration
1	De-activation	Removal of mobilizable tritium and dust from the machine using available techniques & equipment. Removal and deactivation of coolants. Classification and packaging of active, contaminated and toxic material. Removal of all the in-vessel components. OPTION 1: removal of ex-vessel components (if not done in phase 2)	~ 5 years
THE ITER FACILITY IS HANDED OVER TO AN ORGANIZATION AT THE HOST COUNTRY RESPONSIBLE FOR THE COMPLETION OF DECOMMISSIONING
Radioactivity decay period		The vacuum vessel radioactivity is left to decay to a level which allows extraction of vessel sectors into the tokamak building (during phase 2) for size reduction & disposal. No site activities are required except security and monitoring.	A few decades.
2	Final Dismantling & Disposal	removal of vacuum vessel sectors and their size reduction by remote/semi-remote operations OPTION 2: removal of ex-vessel components (if not done in phase 1) classification & packaging of active, contaminated and toxic material	~ 6 years
