Minimax Tests of Composite Null Hypotheses Applied to Nuclear Material Balances
Abstract: This report describes the application of minimax tests to the assessment of a nuclear material balance. The approach allows safeguards authorities and nuclear materials accountants to assess a balance taking realistic account of operating contingencies in facilities processing nuclear material. The contingencies handled are: false alarm risk (composite null hypothesis test size), the effect of measurement variability, unmeasured hold-up and uncorrected bias. The report describes the numerical solution for choosing the test acceptance region in terms of: the tolerance limits for hold-up and bias, the material balance measurement error standard deviation and the desired test size. The numerical method is easy to use. The method is applicable to balance closure under international safeguards as well to balance closure as part of the inventory control program in a process area.
Keywords: material balance test, uncorrected bias, hold-up.
