SATIF-10, CERN 2-4 June 2010 EURISOL-DS European Isotope Separation On-Line Radioactive Ion Beam Facility The main objectives of the EURISOL Design Study were: to show the reliability of the next-generation European ISOL Radioactive Ion Beam (RIB) facility as well as the consistence of it’s key elements: driver accelerator, target/ion-source assembly, mass-selection system and instrumentation; to find the possible cross-interest of the scientific and research areas with other actual European projects and existing laboratory infrastructures; to come out with the key technologies and the engineering solutions which need to evolve in order to progress on such kind of projects;

SATIF-10, CERN 2-4 June 2010 CONCLUSIONS Activation – the key parameter for: Future maintenance of the facility and each sector of it Evaluation of the facility waste production (Type and quantity) Geometry – needs particular attention on this case because: Main element of the system, extraction tubes, are the source of the direct neutron leak Due to the necessity of exchanging/replacing various elements of the system from time to time and to the requirements of the high safety level, the geometry becomes more complicated Dose - determination of this value is fundamental for: Decision on choice of the access type for the different parts/sectors of the facility Shielding requirements Conditioning/restrictions on the operation and maintenance of the facility Project supported by the European Commission under the FP6 “Research Infrastructure Action- Structuring the European Research Area” EURISOL-DS Project Contract no. 515768 RIDS. Part of the work has also been supported by the Portuguese Foundation for the Science and Technology (FCT) in the framework of the projects CERN/FP/83586/2008 and POCI/FP/81951/2007
