摘　　要：燃料组件破损直接影响了反应堆的安全运行,分析燃料组件破损原因是燃料组件研发改进的重要环节。通过破损燃料组件水下解体、破口位置定位、破口试样取样等关键技术的研究,建立了破损燃料组件热室检查方法。研究结果表明,该技术路线合理,检查方法可行,为热室条件下开展燃料元件破损检查提供了技术途径。Fuel assembly damage directly influences the safe operation of the reactor. Analyzing the cause of fuel assembly damage is the key process of the fuel assembly development and improvement. This paper established the thermal chamber inspection method for the damaged fuel assembly, by studying the key technologies such as underwater collapsing, localizing the break and taking crevasse samples of the fuel assembly. The study shows the technical route is rational, and the method is practicable, which have provided technical approaches to check the damaged fuel assembly in a hot cell.
