One of the research lines at SCKoCEN is focussed on the investigating experimental methods for the burnup determination of spent fuel elements. In the past a version of the so-called Fork Detector has been designed and built at SCKoCEN and is in use at the Belgian Nuclear Power Plant of Doel. The Fork Detector relies on passive neutron and gamma measurements for the assessment of the burnup...

As a part of light water reactor (LWR) spent fuel verification technology improvement, the IAEA developed a Fork Detector (FDET) in which neutron detectors were changed from fission chambers (FCs) to boron-10 (B-10) lined proportional counters in order to avoid the difficulties in the transportation and deployment of fission chambers containing fissile materials.
The validation experiment to...

The development of non-destructive assay (NDA) capabilities to improve partial defect verification of spent fuel assemblies is needed to improve the timely detection of the diversion of significant quantities of fissile material. This NDA capability is important to the implementation of integrated safeguards for spent fuel verification by the International Atomic Energy Agency (IAEA) and would...

The unattended gamma emission tomography (UGET) for spent nuclear fuel verification is an on-going project in the IAEA member states' support program. In line with the long term R&D plan of the IAEA Department of Safeguards, it is anticipated that this effort will help develop "more sensitive and less intrusive alternatives to existing NDA instruments to perform partial defect test on spent...

Gamma emission tomography (GET) for spent nuclear fuel verification is the subject for IAEA MSP project JNT1955. In line with IAEA Safeguards R&D plan 2012-2023, the aim of this effort is to “develop more sensitive and less intrusive alternatives to existing NDA instruments to perform partial defect test on spent fuel assembly prior to transfer to difficult to access storage". The current...

A new prototype instrument, hiRX (high resolution X-ray), offers a paradigm shift for plutonium assay in nuclear spent fuel. This new approach offers direct, active, nondestructive interrogation of nuclear spent fuel for plutonium content. This instrument is based upon technology known as monochromatic wavelength dispersive X-ray fluorescence (MWDXRF) which utilizes two doubly curved crystal...

Cadmium zinc telluride detectors (CdZnTe) have found a wide application in non-destructive assay measurements in the IAEA’s verification practice. It is because of their form factor, usability, sensitivity and good spectral characteristics that they are extensively used for fresh and spent fuel attribute test measurements. Until now, the series of CdZnTe detectors utilized in the IAEA have...
