Robotized analysis of uranium and plutonium in fresh and spent nuclear fuels
At the European Institute for Transuranium Elements, robotised quantitative analysis of uranium and plutonium in fresh and spent nuclear samples is in use. The development of this technique was initiated mainly to reduce the occupational (finger) dose during the analysis. The possibility of unattended overnight analysis by robots is an additional benefit that can help cope with an increasing sample throughput. The more compact setup of the automats (the space needed when compared to manual operation is reduced by a factor of about 4) and the reduction in the analytical staff (one analyst with a robot can handle the same number of samples as six analysts, even before considering the unattended overnight operation) amortises the investment cost in 1 yr. The working schedule of a robot is determined by an expert system, which selects from a manual of analytical procedures according to the sample characteristics and which optimises the analysis conditions, such as sample size and spike type. The robot reads the identity of a sample from an attached barcode and receives its instruction from the expert system on request.
