Development of safeguards system simulator

Suzuki, Mitsutoshi; Ihara, Hitoshi

It is increasingly important to evaluate a cost-effective performance for the safeguards system. In order to design an advanced safeguards system, we have initiated the development of a safeguards system simulator. The simulator is composed of several interrelated cores and a separate core is planned to develop. The NMA core is a NRTA code that has been improved on an objective-driven processor. A multivariate and multi-scale core with a wavelet technique has been developed to provide an algorithm of process monitoring. In addition, a multiple optimization core has been developed with a fuzzy-linear-programming technique to investigate the cost-effective performance of the conceptual safeguards system. It is shown that a combination of flow-meter and non-destructive assay can be applied to the system in a cost-effective manner.
