研究堆跟随燃料组件抗落棒冲击寿命考验研究

Anti-scram-strike Lifespan of Follow-Fuel-Assembly for Research Reactor

在跟随燃料组件抗落棒冲击荷载研究的基础上,对跟随燃料组件抗落棒冲击进行了寿命考验研究,其内容包括跟随燃料组件抗落棒冲击寿命考验前的完整性检查,300次抗落棒冲击寿命考验,以及寿命考验后的完整性检查。研究结果表明:控制棒可移动线圈驱动线上的跟随燃料组件设计和结构合理,使用寿命能够满足设计要求;跟随燃料组件在设计寿期内不影响整个驱动线的性能,其可靠性良好。

Based on the study of anti-scram-strike charge of follow-fuel-assembly for research reactor, the test for anti-scram-strike lifespan of follow-fuel-assembly was done including the full size check before test, anti-scram-strike lifespan test and the full size check after test. The results show that the design and structure of follow-fuel-assembly in the control rod drive line is reasonable and reliable, and its lifespan meets design demand; during the lifespan, follow-fuel-assembly has no effect on the performance of control rod drive line, and its reliability is excellent.
