The aim is to overcome resistance to change, a significant barrier that is endemic in the nuclear industry, and thus gain acceptance of this new approach. Field testing will show companies that the tool is fit for purpose and can deliver in real-world, user-facing projects with the performance needed for a wide range of application areas. We plan to do this by providing the SLCs undergoing characterisation activities with the use of a ViridiScope® on-site for a period of deployment with an ROV, commercial in-situ counting equipment, training and support to allow them to fully test and assess the sampling tool in an active operational environment with high levels of radioactivity. It will show that this technology can offer considerable advantage over conventional approaches, delivering characterisation rapidly, at least cost and with least effort.
