N2 - The investigation of experimental methods for safeguarding spent fuel elements is one of the
research areas at the Belgian Nuclear Research Centre SCK•CEN. A version of the so-called Fork
Detector has been designed at SCK•CEN and is in use at the Belgian Nuclear Power Plant of Doel
for burnup determination purposes. The Fork Detector relies on passive neutron and gamma
measurements for the assessment of the burnup and safeguards verification activities. In order to
better evaluate and understand the method and in view to extend its capabilities, an effort to model
the Fork detector was made with the code MCNPX. A validation of the model was done in the
past using spent fuel measurement data. This paper reports about the measurements carried out at
the Laboratory for Nuclear Calibrations (LNK) of SCK•CEN with a 252Cf source calibrated
according to ISO 8529 standards. The experimental data are presented and compared with
simulations. In the simulations, not only was the detector modeled but also the measurement room
was taken into account based on the available design information. The results of this comparison
exercise are also presented in this paper.
