Uncertainty Quantification of Multi-Component Isotope-Separation Cascade Model

Pagination or Media Count:
Monte Carlo uncertainty quantification UQ capability has been added to a code for modeling multi-component steady-state isotope-separation enrichment cascades to characterize the propagation of uncertainties in input data that define the cascade and the feed. Random samples of error for every computational input are drawn from its individual uncertainty distribution and added to the inputs, creating a set of enrichment cascade problems with perturbed inputs. The set of problems is solved using the verified code. The cascade outputs are then characterized using the empirical cumulative distribution. The uncertainty output data are analyzed to gain new insights into the behaviors of enrichment cascades. The UQ capability is an investigative tool that can be used to explore current and new questions of interest regarding enrichment.
