摘　　要：10MW高温气冷堆的燃耗测量系统是采用非破坏性高纯锗γ谱仪在线监测来确定燃耗值,利用MCNP4A程序对测量系统的衰减因子进行计算,基于核燃料裂变核索的γ射线能谱分析,以137Cs和134Cs核素活度作为测量对象,并对燃耗测量结果进行讨论。The burnup value for burnup measurement system of 10MW high temperature gas-cooled reactor was determined at on-line monitor by mean of nondestructive high-pure germanium gamma spectroscopy, An attenuation factor of the measurement system was calculated using MCNP4A code. Based on analysis of gamma-ray spectra for nuclear fuel of radioactive fission products and measurement of ^137Cs and ^134Cs activities, results of the burnup measurement were discussed.
