Spent Fuel Dissolver Predictive Modeling: Ⅰ. Application of the Adjoint Sensitivity Analysis Methodology for Nonlinear Systems with Operator-Type Responses

摘要

The dissolver produces feed stock for the chemical separation processes in an aqueous nuclear fuel reprocessing. In this work, we consider the compartmented rotary dissolver drum (Lewis and Weber) depicted in Figure 1, with the liquid flow diagram shown in Figure 2. This dissolver model was selected as a test case because of its potential applicability to investigate diversion activities associated with proliferation and international safeguards. It comprises eight active compartments; compartment 9 is used for rinsing.
