核电循环冷却水一氯胺反应动力学规律

摘要

Desinfection of cooling water system of nuclear plant is the research focus for nuclear power sys- tems. With the circulating cooling water module from Dampierre nuclear plant in France, we study the kinetic of consumption of monoehloramine as a desinfeet and determine that the consumption of monochloramine with raw water is the first-order kinetic reaction, and the rate constant is 0. 002 min - 1. The analysis of consumption of monochloramine with Fe3 ＋ added in shows that, the Fe3＋ has no significant effect on the consumption of monochloramine. The results can provide technical support and guidance for the design and management of nu- clear power plants in China.%核电站循环冷却水系统的消毒是核电水系统的研究重点．以法国丹皮尔核电站冷却塔模型为研究对象，进行一氯胺消毒剂的消耗动力学研究，确定以天然原水为循环水介质的一氯胺消耗动力学符合一级反应的动力学模型，其反应速率常数为0．002min^-1；以人工模拟投加Fe^3＋进行一氯胺消耗分析表明，Fe^3＋对一氯胺的消耗无显著影响．
