Irradiation Rig Design and Preliminary Dosimetry Results for CORANI Phase 1 at HANARO Reactor

The CORANI (KAERI/CEA COllaboration for Research reactor Application of Neutron dosimetry and Instrumentations) project is a collaborative effort between KAERI and CEA aimed at validating advanced neutron instrumentation and dosimetry techniques at the High-Flux Advanced Neutron Application Reactor (HANARO). The Phase 1 campaign focuses on neutron field characterization using self-powered neutron detectors and fission chambers, complemented by activation-foil dosimetry. This paper presents the feasibility study results for CORANI Phase 1 to confirm the reliability of the adopted methodologies and provide a solid basis for experimental conditions and irradiation rigs. The preliminary results demonstrate well agreement between the two different measurement systems and confirm the operational parameters for the forthcoming Phase 1 campaign scheduled for the fourth quarter of 2025.
