Description
Remote techniques have been applied to some existing overhead travelling cranes in experimental areas in order to reduce radiation doses to personnel during decommissioning and repair operations.
The presentation will describe the work carried out by EN-HE in collaboration with EN-MEF and EN-STI for two cases (dismantling of a redundant facility and repair of heavy radioactive assemblies) - giving details of crane modifications, vision system arrangements, handling equipment design, operational procedures, and the resulting personnel radiation dose reductions.
The presentation will be completed by the example othe XTAX table repair
In 2012 a large-scale worksite took place in TCC2, a high radiation area at the CERN SPS. The objective was to repair 12 XTAX tables which play a key role in the safe and effective operation of the North experimental areas. In order to optimize the work procedures and reduce the collective dose received by the teams, remote controlled devices have been designed and manufactured purposely for this task. The paper describes the challenging situations encountered and the solutions implemented, and summarizes the lessons learnt from this experience, underlining that the handling of radioactive material in a particle accelerator through its entire life cycle must be carefully studied as from the design stage.
