RPE / RPA interventions RPE / RPA interventions

At each relevant step of the opening scenario and detectors At each relevant step of the opening scenario and detectors activities, RPE / RP will intervene to do RP measurements and collect activities, RPE / RP will intervene to do RP measurements and collect dust for analysis.dust for analysis.

RPE will be in charged to measure, trace and assist transport of all RPE will be in charged to measure, trace and assist transport of all material coming from the radioactive waste area.material coming from the radioactive waste area.

Note that additional persons from the intervening teams and from Note that additional persons from the intervening teams and from safety team will be trained to perform RP measurement and safety team will be trained to perform RP measurement and traceability for the material coming from the conventional area.traceability for the material coming from the conventional area.

Reminder : all material exiting the radioactive and operational zones Reminder : all material exiting the radioactive and operational zones shall not exit the Toroid area, shall be transported via crane to the shall not exit the Toroid area, shall be transported via crane to the radioactive buffer zone on surface, shall be removed and transported radioactive buffer zone on surface, shall be removed and transported under RPE supervisionunder RPE supervision
