摘　　要：The uncertainty to nuclear data is an important part of the total uncertainty of keff calculation value.In order to analyze the nuclear data uncertainty of keff for CEFR,a general expression of sensitivity to an integral quantity was derived based on the generalize perturbation theory(GPT).Using this general expression,the specific calculation formula of the sensitivity of keff was given,and the
