| Summary / Abstract (Note) | The International Atomic Energy Agency uses a concept of “significant quantity” to establish accounting limits and to determine how much nuclear material can be unaccounted for before the construction of a nuclear device becomes possible. Under the current SQ values, some materials could potentially be under-regulated, while others have disproportionately tight accounting practices, thus interfering with optimal safeguards efficacy. This article compares the SQ values of various materials and reviews the categories adopted by a variety of national regulators to show similarities and differences of approaches. The article concludes by offering possible solutions to increase safeguards efficacy and reduce costs, while acknowledging potential drawbacks. All findings and conclusions are based on open-source publications and publicly available information. |
