Radiolysis of Aqueous Ammonia Solutions: Mathematical Modeling
V. A. Grachev, А. Б. Сазонов
Abstract
Abstract A mathematical model has been developed for the radiolysis of an aqueous solution containing the VVER primary coolant components ammonia and boric acid. The test results show that the average deviation of the model calculation results from experimental data does not exceed 35% when processing about 250 experimental data points. This model correctly predicts the temporal evolution of the VVER coolant quality indicators (concentrations of H2, O2, and NH3) and can be used to analyze their behavior at various parameters of the VVER core (temperature, power, boron content, etc.).
