Effect of air flow rate on performances of iodine adsorber in ventilation system of nuclear power plants

The operating air flow rate is one of the influencing factors on the performance of iodine adsorber in the ventilation system of nuclear power plants. Derives the relationship among the purification coefficient of iodine adsorber, system purification coefficient and leakage rate. Based on the experimental data, calculates the leakage rate of the system by the derived formula, and analyses the influence of air flow rate on the three factors. The results show that under the conditions of this experiment, the system purification coefficient increases with the increase of air flow rate, while the leakage rate decreases.
