Abstract:
A plant level framework has been developed for a nuclear recycling facility. A plant level model generally consists of multi-tiered models. The bottommost tier is a unit process model regarding electro-chemical phenomenon. The middle tier is an operation model regarding mechanical handling of the process equipment. The topmost tier is a systemic integration in the level of the plant. Even though a unit process model is fundamental to build higher tier models it takes time to make a model with high fidelity. Therefore, a different strategy for a plant level model building is suggested in this study. One of the important issues that nuclear recycling process must consider is dynamic material flow, which could be done with the help of a unit process model. However, from plant level aspect, it can be simply obtained from mass balance sheet rather than understanding of electro-chemical behavior during process time. A plant level framework was suggested to be able to include dynamic materi
al flow even without a unit process model. Thus, a more reliable unit process model can be added later selectively. The characteristic of the current framework was addressed and evaluated for further improvement. The current version of the plant-level-framework could provide many unforeseeable results which are difficult to obtain by intuition. Nevertheless, the next version will include more function to provide various analyses linked with other nuclear related codes.
