Coupling of SI thermochemical cycle models to thermic

Implementing a nuclear reactor hydrogen production scheme requires robust models of chemical plant and reactor thermal hydraulic behavior and response. Efforts have been conducted in both the transient modeling of the Sulfur Iodine (SI) and Hybird Sulfur (HyS) thermo-chemical cycles. A simplified transient model of the Sulfur-Iodine (SI) cycle is coupled to a THERMIX thermal hydraulic model of the Pebble Bed Modular Reactor 268 (PBMR 268) and a point kinetics model. A control volume approach is used in analysis of the chemical plant. A steady state solution of the SI cycle model and THERMIX model is attained. A transient is initiated via reactivity insertion in a simple point kinetics model. Results from a nuclear reactor driven transient are presented, as well as suggestions for future work regarding chemical plant induced transients
