The area method is one of the subcriticality measurement techniques for the accelerator driven system (ADS).
In this study, uncertainty of a spatial correction factor, Bell factor, due to cross section data was quantified for MA loaded ADS core.
In order to discuss the spatial distribution of the uncertainty of Bell factor, we evaluated the sensitivity of the subcriticality and the area ratio.
