  • Design, manufacturing and testing of a robotic system (TRR) for the removal of tubes from a Latina Magnox steam generator with subsequent melting and radiological characterization : Feasibility study and cost estimates of dismantling Latina


Two separate activities were undertaken and are described respectively in this report. The first activity was to assess the technical feasibility and the economic convenience of the melting and recycling of the low level radioactive steel coming from the dismantling of Magnox or gas/graphite type reactors. A robotic system was developed to cut and remove steam generator tubes at Latina power station, thus allowing the reduction of doses absorbed by operators during the tubes cutting campaign. The retrieved material was characterized radiochemically, melted and characterized again with a view to reuse. The second activity was to study the feasibility of the full dismantling of all four steam generators of Latina in terms of techniques to be used, related costs and time schedule. An analysis was performed to assess the cost effectiveness of melting the total steel masses that should come from the dismantling, the production of secondary and residual contaminated wastes and the way of reusing the produced material. The hypothesis of the construction of a new melting plant near the dismantling site was evaluated, as well as the possibility of a transportable one.
