Future developments of safeguards analysis
Developments towards reduced uncertainties in measurements made for Safeguards purposes are leading to the convergence of measurement techniques in the field between operators and ECSAM laboratories. The question arises as to how independent the measurements are and, consequently, whether independent Safeguards measurements are really necessary for verification. The development of the analysis techniques for measuring the fissile material content of the dissolver solutions and the output material (uranium and plutonium as oxides or nitrates) is outlined and it is shown how pressures from two sides (the need for small measurement uncertainties and the increasing recognition of the role of traceability in the measurement chains) are presently forcing a convergence of techniques. Duplications occurs in the techniques used, the instruments employed (and their associated software) and the reference materials on which the measurement results are ultimately based. The problem is discussed with reference to present analytical problems and the techniques employed to overcome them and conclusions are made on the need to redeploy resources for more efficient use of facilities and personnel.
