Improve Transuranian Wastes Measurements by Non-Destructive Passive Neutron Assay Using a Matrix Correction Method by Neutron Transmission

We address the problem of coefficient calibration choice in transuraniuan wastes measurement by non-destructive passive neutron assay. The well-known matrix correction method by neutron transmission, provides an appealing solution and is adapted to our waste issue. The numerical calibration of our assay device and the setting of all parameters needed for the transposition in-situ are realised with MCNP. The results obtained with these modelling are experimentally validated in considering different types of test drums.
