文章对某单位的锆复合板反应器设备泄漏原因进行了分析,先后采用两种方法进行泄露修补。对比两次不同的返修方法,认为对安全运行多年的设备,其结构和应力分布已经固化,如果有泄漏,漏点不会很大,但因为设备冷态检查与最终使用工况有较大区别,返修完成前后应模拟工况进行热试,这样才能彻底找到漏点,一次性返修好。对这台设备的返修总结,为类似使用多年的设备返修提供经验, The paper analyzes the cause of leakage of a unit zirconium composite plate reactor equipment, has used two methods to leak repair. Contrast two different rework methods, that the safe operation of equipment for many years, the structure and stress distribution has been cured, if there is leakage, the leak will not be great, but because of equipment cold state inspection and the final use of a greater difference , Rework before and after the simulation should be carried out hot test conditions, so as to find the leak completely, one-time rework well. Rework on this equipment summary, similar to the use of many years of equipment repair experience,
