Dynamic Simulation of Uranyl Nitrate Crystallization Process

The paper addresses the dynamic modeling of the uranyl nitrate crystallization process. The paper is filling the gap of the current literature in the regeneration of nuclear fuel, improvement of the process understanding, and future needs in controllability and operability for safety purposes to obtain a final product of the process in the pure state. Basing on the existing kinetic studies on uranium crystallization, a novel mathematical model of the uranyl nitrate crystallization process is proposed describing the heat and mass transfer phenomena. Sensitivity analyses are provided for the prediction of the main outlet parameters of the crystallization process and to improve the process design for enhanced operational flexibility.
