Dismantling of cells 22, 23 and 24 for the fabrication of caesium and strontium sources at CE Saclay ORIS pilot facility

The cleaning an dismantling of the three hot cells in ORIS Industrie building are not very heavy operation. The surface of the work is reduced; so it is just possible to have only four or five operators at the same time. It is the reason for a long operation delay. The main technical difficulty of these operations consists in: - very high level of radioactivity measured on same apparatus (7000 rad on a press). They must be evacuated without disturbing the industrial production of ORIS Industrie. - putting of working area and the identification of relations between the different intervening parties
