Diamond detectors for neutron flux measurement during transient neutron flux changes
Popis výsledku v původním jazyce
The abstract discusses the development and testing of diamond-based detectors for precise neutron flux measurement, particularly during fast reactor transients. Accurate neutron flux measurement is essential for reactor operation and predicting behavior during rapid changes. Since 2017, these detectors have been developed in collaboration with CEA Saclay and are currently being tested at the VR-1 reactor. Diamond detectors, though rarely used in reactor cores, show promise for this application due to their ability to handle rapid flux changes. To achieve accurate measurements, advanced detection and data processing systems are required. Challenges include separating neutron-induced signals from noise and gamma radiation. Techniques like pulse shape analysis and subtractive gamma compensation are being tested to address these issues. The subtractive gamma compensation method is under experimental evaluation using diamond detectors at VR-1 and adjacent laboratories, with preliminary results anticipated by early 2021. This detection system is intended for use in a new experimental device focusing on rod SCRAM transients, currently under development at the Czech Technical University in Prague.
