"No country has yet encountered major problems in its nuclear fuel supply specifically because of commercial disruptions. However, past political constraints on supply may be part of the motivation for countries like Iran to seek enrichment capability. Thus far it is unclear what other countries might be on the fence about acquiring a full fuel cycle and could be swayed not to enrich if an effective assurance mechanism could address the simply political risk. It is important for IAEA to identify these countries and the assurances they would need so that the best supply assurance mechanism can be crafted. Anticipating nuclear needs—not just for enriched uranium but also for fabricated fuel, transport, spare parts, etc.—and deciding whether and how government should help satisfy such needs is the best way to ensure that the industry develops in ways that serve the public's interests."
