Assessment of pilot unit configurations using neutron backscattering and OpenMC simulation
摘要
The objective of this work is to promote a nucleonic control system for a laboratory-scale pilot unit using the neutron backscattering technique, supported by OpenMC simulations. A reference scan showed that the four trays of the unit were in place and contained approximately the same amount of water. The diagnostic scan revealed a positive correlation between peak intensities and the components of the trays, according to their hydrogen content: gasoline > diesel > water > borated paraffin. The results provided by OpenMC simulations are in agreement with the experimental data, validating the measurements and the methodology developed using this technique.
