Abstract
An advanced neutron detection system for highly localized in-core measurements developed in the Laboratory for Reactor Physics and System Behaviour (LRS) at École polytechnique fédérale de Lausanne (EPFL) it is used to characterize the neutron flux of the SUR 100 zero-power reactor of the Institut für Kernenergetik und Energiesysteme (IKE) operated at the University of Stuttgart. The small size of its experimental channels requires the use of miniature detectors for a proper characterization of the neutron flux profiles, not achievable with conventional detection techniques. An experimental campaign is carried out in the IKE laboratory by means of an academic collaboration established with the EPFL-LRS.
Miniature neutron detectors are disposed in different arrangements in order to achieve high spatial resolution measurements of the neutron flux profiles in the experimental channels of the reactor
