SM/ADS-08 GUINEVERE: Construction of a Zero-Power Pb Fast ADS at Mol A. Billebaud, and the DM2 partners LPSC–CNRS–IN2P3/UJF/INPG, Grenoble , France Corresponding Author: billebaud@lpsc.in2p3.fr The GUINEVERE project is running since 2007 and is part of the EUROTRANS Integrated Project of the 6th EURATOM Framework Programme. It consists first in the construction of a lead fast ADS mock-up at SCK·CEN Mol (Belgium) for the purpose of ADS subcriticality monitoring experiments, and beyond in support to the design of a Transmutation Experimental Facility (MYRRHA/FASTEF). To do so the VENUS reactor (SCK·CEN) will be coupled with a new GENEPI neutron source under construction by CNRS (France). To accommodate this new source (a 250 keV deuteron accelerator) in a vertical coupling configuration, the VENUS building is being heightened. In parallel the reactor core is being modified to be loaded with fuel assemblies made of enriched Uranium and solid Lead moderator pins, and hold radial and axial Lead reflectors. A new safety and control rod system is also under development. The new GENEPI-3C neutron source is designed to be operated in pulsed mode but also in continuous
mode to investigate the current-to-flux reactivity indicator in representative conditions of
a powerful ADS. In this latter mode it will be also possible to make short beam interruptions at
a fixed frequency to have access to the neutron population decrease as a function of time. The
vertical beam line will have the distinctive feature to be retractile, allowing target changing or
complete removal (for critical configuration for example). The accelerator will be first completely
assembled at LPSC Grenoble for beam characterization before to be transferred in Mol.
We will present in this paper the status of this experimental facility assembling, and foreseen
experimental programmes in the framework of fast transmutation system studies. |
