CLEANDEM, a Cyber physicaL Equipment for unmAnned Nuclear DEcommissioning Measurements

Résumé

Human intervention is still required nowadays for most operations conducted during the Dismantling & Decommissioning (D&D) steps, which cover a wide range of radiological conditions: from the harsh initial conditions, nearly identical to when operating, to the final decommissioning steps where radioactivity has been removed. The goal of the three years EU-funded CLEANDEM project (Horizon 2020 Euratom Nuclear Fission and Radiation Protection Research call), led by CEA List with the support of ARTTIC, is to deliver a unique platform which will support the end-users' operations, from the initial radiological assessment to the final characterization of the facility, while enabling their continuous monitoring during the D&D operations. Ten leading actors from four European countries' nuclear industry (CAEN, ORANO, ANSALDO, RINA, TECNALIA, SOGIN, AiNT) and research (CEA, INFN, ENEA), have joined their expertise and efforts in the CLEANDEM consortium to develop a mobile unmanned ground platform (UGV), equipped with upgraded highly-mature detection technologies for 3D-localized radiological measurements. These will complete the facilities' available data into a 3D and fully detailed Digital Twin of the surveyed area, thus improving the planning and traceability of the D&D operations. The project started in March 2021 with the end-users' and stakeholder' input collection by ORANO leading to the concepts of operations and technical specifications, starting point for the technical developments. The first developments concern the upgrade of radiological sensors with * the improvement of low-cost sensors for rapid neutron and gamma (INFN's developments on the MiniRadMeter gamma counters/spectrometers and gamma-blind MiniSiLiF neutron counters), and distributed dose rate mapping (CEA List's OSL optical fibers technology coupled to 3D shape-sensing to access narrow spaces). * Then, neutron/gamma detection and identification sensors improvements (CAEN's PSD Phoswich alpha/beta large surface contamination monitor, and CEA List's upgrade of coded-aperture Nanopix gamma imager for hotspot localization); * And, last: air and surface contamination monitoring (with ENEA's cryogenic system for radioactive radiocarbon dioxide monitoring 14CO2, and CEA List's pixelated plastic scintillators for beta/gamma surface contamination). Most of the sensors will be embedded on the RB-VOGUI unmanned platform equipped with a UR 5e robotic-arm upgraded by TECNALIA and ANSALDO, for remote and autonomous operations. All gathered data are then to be passed for the continuous update of the Digital Twin containing all available radiological information, developed by RINA-CSM. The use cases selected by SOGIN for in-situ demonstration at the EUREX Saluggia plant, based on the scenarios defined by end-users shall also be presented; as well as AiNT's development of the concept for the training programme targeted at the end-users network.
