TAILIEUCHUNG - Recommendations for the selection of in situ measurement techniques for radiological characterization in nuclear/radiological installations under decommissioning and dismantling processes

In this paper, in-situ radiological characterisation by means of non-destructive techniques is studied and analysed in the context of the different constrained environments (identified as radioactivity, materials, accessibility and other hazards) that may be encountered in the nuclear facilities undergoing decommissioning and dismantling. | Progress in Nuclear Energy 137 2021 103761 Contents lists available at ScienceDirect Progress in Nuclear Energy journal homepage http locate pnucene Recommendations for the selection of in situ measurement techniques for radiological characterization in nuclear radiological installations under decommissioning and dismantling processes Khalil Amgarou a Frederic Aspe b Raquel Idoeta c Margarita Herranz c a Commissariat a l energie atomique et aux energies alternatives CEA DES DDSD DTPI STRD GRDT Marcoule BP 17171 30207 Bagnols sur C eze Cedex France b Onet Technologies Direction Technique 970 Chemin des agriculteurs 26701 Pierrelatte France c Nuclear Engineering and Fluid Mechanics Department University of the Basque Country UPV EHU Pza Ingeniero Torres Quevedo 1 48013 Bilbao Spain A R T I C L E I N F O A B S T R A C T Keywords In this paper in-situ radiological characterisation by means of non-destructive techniques is studied and analysed Nuclear installations in the context of the different constrained environments identified as radioactivity materials accessibility and Decommissioning and dismantling other hazards that may be encountered in the nuclear facilities undergoing decommissioning and dismantling. Constrained environments As a complement to a previous paper Aspe et al. 2020 the present one gives a global guidance to assist with the In-situ measurements decision making process regarding the selection of in-situ measurement techniques that could be applied in such constrained environments. In addition from the definition of the investigation objectives and for each one of the most common in-situ measurement techniques a brief description is given about the impact of the above constraints and how to integrate them onto the system definition including the experimental design the mechanical integration and the data management to properly define the best radiological characterization methodology. Moreover complementing this general view all .
