Dose limit <0.1 mSv per year <0.1 mSv per event <50 mSv per event

Reduction of radioactivity release to as low levels as reasonably achievable, but ensure they do not exceed project release guideline for normal operation. Reduce probability of releases with the aim to decrease releases Ensure they do not exceed project release guideline for Reduce likelihood and

Safety goal incidents.

Operational State Normal operation: events and plant conditions that are planned and required for ITER’s normal operation, including some faults, events and conditions, which can occur as a result of the ITER’s experimental nature. Incident: deviation from normal operation, including event sequences or plant
