Abstract

•Sector-shaped scintillation detectors based neutron coincidence counter described.•Suitability for neutron coincidence counting explored via MCNPX.•Performance of the system studied considering different thicknesses of scintillators.

A simulation based on the Monte Carlo method is described which has been performed using MCNPX 2.6.0, to model the geometry of a sector-shaped liquid scintillation detector in response to coincident neutron events. The detection of neutrons from a mixed-oxide (MOX) fuel pellet has been simulated for different thicknesses of scintillators. A layer of lead has been used to reduce the gamma-ray fluence reaching the scintillator and, the effect of lead for neutron detection has also been estimated by considering different thicknesses of lead layers.
