The US strategy to dispose of all spent nuclear fuels (SNFs) and high-level wastes in engineered geologic repositories has a sometimes-overlooked consequence, namely, the need to maintain domestic and international safeguards in perpetuity. The current International Atomic Energy Agency (IAEA) criterion for spent fuel from safeguarded reactors is to maintain containment and surveillance only. Some scenarios require quantitative estimations of fissile materials to deter certain types of diversions, but limitations of available technologies would make it difficult to make such requirements mandatory. However, a new state system entering the IAEA safeguards regime has to have some verification. The time between reactor discharge and geologic disposal may be 25 to 100 yr. Therefore, safeguards during surface storage will be enormously expensive, but it is possible to design simple and less expensive safeguards systems for retrievable storage locations. Management of SNF in perpetuity is very difficult from all other nuclear materials management, and consideration should be given to modifying current IAEA goals to meet the unique requirements of long-term SNF management. In the context of a recent US Department of Energy effort to develop a research and development plan, this paper proposes safeguards concepts for the US spent-fuel management system. 4 refs.
