摘要:

核电厂通风系统中的碘吸附器性能受到多种因素的影响,运行风量是其中之一。推导了碘吸附器净化系数、系统净化系数和泄漏率的关系,并在实验数据基础上,利用推导公式计算了系统的泄漏率,同时分析了风量对三者的影响。结果表明,在本文实验条件下,随运行风量的增大,系统净化系数增大、泄漏率减小。

Abstract:

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.
