    The EUROTRANS project is an integrated project in the 6th European Framework Program in the context of Partitioning and Transmutation. It 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. Since 1998, SCK•CEN has been designing a multipurpose ADS for R&D applications – MYRRHA. In its 2005 version, MYRRHA consists of a proton accelerator delivering a 350 MeV*5 mA beam to a windowless liquid Pb-Bi spallation target that in turn couples to a Pb-Bi cooled, sub-critical fast core of 50 MW thermal power. The EUROTRANS partners have accepted the SCK•CEN offer to use MYRRHA as a starting basis for the XT-ADS design. Instead of starting from a blank page, this allowed optimizing an existing design towards the XT-ADS needs within the limits of safety requirements. Many options have been revisited in 2005 – 2006 and the framework is now set up. In this paper we present the general configuration of the XT-ADS core and primary system, with a particular focus on the evolution from MYRRHA and the rationale behind.
