摘　　要：为验证中国工程试验堆(CENTER)燃料组件设计,在燃料组件正式定型前需开展组件辐照考验,CENTER燃料组件在高通量工程试验堆(HFETR)内采用随堆辐照方式进行辐照考验。根据CENTER燃料组件特点,开展了HFETR辐照考验CENTER燃料组件燃耗计算方法研究,确定了CENTER燃料组件辐照考验堆芯物理计算采用镶嵌耦合方法。结果表明,燃料组件平均燃耗计算值与测量值偏差为3.25%,满足辐照考验要求。CENTER fuel assembly irradiation test should be carried out before the fuel assembly is formally designed, and the CENTER fuel assembly would be irradiated in HFETR to complete the fuel burn-up test. To ensure the success of the irradiation test and meet the test requirements, the accuracy of power calculation and measurement of fuel assembly in the process of irradiation test should be studied. According to the characteristics of CENTER fuel assembly, the mosaic coupling method was studied and determined. The fuel assembly was irradiated in HFETR, and the test is conducted. The difference of the fuel burn-up between calculation and measurement is 3.25%, and the burnup of CENTER fuel assembly irradiation test meets the test requirements.
