Short Notice Random Inspection (SNRI) regime at a low enriched uranium fuel fabrication plant in Spain

Full text: The safeguards criteria of the IAEA require that, in addition to an annual verification of the physical inventory taking of facility operators, a regime of randomised inspections be implemented at fuel fabrication plants, in order to achieve 100% verification coverage for domestic transfers on nuclear material. The advance notification period for such randomised inspections depends on the time that such material is available for verification, or commonly referred to as 'residence time'. In the case of this particular facility, the residence time is almost zero; therefore the SNRI scheme being developed is based on a very short inspection notification time to match the very short residence time, in order to achieve safeguards goals. The paper will address the implementation issues and activities to be performed together with a regional inspection authority. (author)
