    The EUROTRANS project is an integrated project in the 6th European Framework Program in the context of Partitioning and Transmutation (P&T). The objective of this project is the step-wise approach to a European
    Transmutation Demonstration. This project aims to deliver an advanced design of a small-scale Accelerator Driven System (ADS), XT-ADS, as well as the conceptual design of a European Facility for Industrial Transmutation, EFIT. The main objectives of the XT-ADS are: demonstration of the ADS concept, provide a test facility for transmutation and provide irradiation possibilities in conditions representative for EFIT operating conditions. The latter allows the use of the XT-ADS as a structural material testing facility as well as
    an aid for the fuel qualification for EFIT. The XT-ADS core is based on MOX fuel with relatively high Pucontent and is cooled using a Lead-Bismuth Eutectic (LBE). The combination of these two components results in a fast spectrum core. Using both stochastic and deterministic neutronic codes, a core is designed which can house up to eight experimental positions, the in-pile-positions, which are accessible through the cover of the reactor. This allows for retrieval during cycles but also the possibility to design dedicated irradiation loops. A five-step outward-to-inward reshuffling scheme allows a flexible operation of the machine.
