Abstract
The ARIANNE (Advanced Reactor Investigative Analysis of Neutron Noise Experiments) project aims at testing and assessing the performances of the main neutron noise techniques (Feynman-alpha, Rossi-alpha, and Power Spectral Density) for estimating the kinetic parameters featuring the fast nuclear facility VENUS-F. Neutron noise techniques are very important to monitor the reactor kinetic features during its steady-state operation, ensuring its safe operation. While noise techniques are established methodologies in thermal reactors, their application to fast systems is quite scarce, demanding dedicated experimental efforts. Due to its simple geometry and low thermal power, VENUS-F is ideal for studying neutron kinetics with noise techniques.
The experimental campaign would be performed both in critical and slightly sub-critical configurations, exploiting fission chambers as neutron detectors. The experimental results obtained with the different techniques would be compared one to each other and against high-fidelity, Monte Carlo simulations of the experimental configurations. The project is expected to contribute to the general know-how of experimental techniques for Gen-IV fast reactors, providing specific insights regarding the range of applicability and associated needs of state-of-the-art neutron noise techniques applied to fast systems. In addition to the methodological outcomes, the experimental evaluation of the kinetic parameters featuring VENUS-F would be also valuable for the validation of numerical codes and nuclear data libraries applied to heavy-metal cooled fast reactors, like ALFRED and MYHRRA, contributing to the deployment of the Lead Fast Reactor technology.
