Abstract

The Institute for Cryogenic and Isotope Separation Rm. Valcea, through its tradition of developing hydrogen isotope separation technologies, is concerned with the development of these technologies in order to ensure the efficient management of the tritium isotope, respectively, of tritiated water generated by nuclear reactors and beyond. A technological installation, which is under development, is defined as an advanced modular system based on the development of tritium separation technologies through the combined electrolysis and catalytic exchange (CECE) process coupled with an isotopic permeation cascade.The current stage of the installation development, which is for the CECE isotopic separation process, allows for operation in three modes: (1) a CECE module with two liquid-phase catalytic exchange (LPCE) columns in series and an electrolysis cell, (2) two CECE modules, with the second module being supplied with water from the LPCE column bottom, or (3) two CECE modules, with water directly from the electrolyzer of the first CECE module.To represent the CECE isotopic separation process, a mathematical model was previously developed, with the results intercompared with the experimental ones. The mathematical model representing isotopic separation in the advanced modular CECE system has been upgraded to reflect its specific technological configuration and the three operating modes. Subsequently, the theoretical predictions generated by the model will be validated against experimental data.This paper presents the calculation scheme corresponding to the operation of the CECE modular system. Due to the nonstationary regime of the process, where isotopic concentrations in the liquid, vapor, and gas phases fluctuate over time, reaching the target concentration requires a significant duration. Consequently, following the initial verification of the CECE mathematical model, we performed a preliminary theoretical analysis. This approach minimized the experimental iterations and associated costs while providing a strategic framework for optimizing the installation's performance and validating theoretical data.This paper presents a parametric analysis of the isotopic separation process, indicating the operating range for maximizing the tritium concentration while respecting the gas decontamination requirements at the exit of the technological installation.
