Due to the lack of sufficient in-line instrumentation, process control and process monitoring of a nuclear fuel reprocessing plant require an efficient analytical laboratory for the physical and chemical assay of the various process constituents and intermediate or final products. The demand for efficiency, reliability and short response time calls for the use of computer support in the laboratory, which is usually realized by laboratory information systems covering both levels: analytical instruments automation and laboratory organization. Within the frame of laboratory organization the selection of the appropriate analytical method, the definition of the analytical steps (including sample preparation, measurement procedure, evaluation, etc.) and scheduling the sequences in laboratory work is an inherently complex task. It depends on a variety of input informations and implies multiple decision steps, which often must be revised repeatedly during the analytical treatment because of unexpected analytical results
