International safeguards for an automated MOX (mixed-oxide) fuel fabrication facility
This report presents details of our recent examination of international safeguards issue relevant to a state-of-the-art, mixed-oxide (MOX) fuel fabrication facility, located in the United States, which may be placed under International Atomic Energy Agency (IAEA) safeguards. The unique aspects of this study are: (1) recognition of a widespread industrial practice using a rather limited number of quality assurance measurements for the operator's materials accountancy system; (2) investigation of a bimonthly materials balance closing, which does not conform to timeliness goals of the IAEA but is dictated by the facility; and (3) consideration of the IAEA's need to optimize inspection resources. Assuming IAEA's accommodation of reasonable facility-specific limitations, we conclude that it is possible to achieve many of the IAEA safeguards goals, such as timely detection of both abrupt and protracted losses. However, likely constraints on IAEA inspection resources as well as limitations in present nondestructive assay techniques for verifying plutonium contents of large fuel assemblies would decrease the detection probabilities for several falsification strategies. 4 refs., 4 figs., 10 tabs.
