The analysis presented in the paper is focused on the characterization of uncertainties induced by cross-section data in the correction factor calculation for the manganese sulphate bath technique. The manganese sulphate bath is the most common technique used for the determination of neutron source emission rate and is deployed in many metrology institutes around the world. Advances in computational methods and computational power, with the improvement of the nuclear data libraries, including more information about the cross-section data covariances, provide an opportunity for full characterisation of the contribution of the calculations to the final value and its uncertainty. In this paper, the super-sequence SAMPLER module of the SCALE6 system, that implements stochastic techniques is used to assess the uncertainties in computed results. Reaction rates on all nuclides of the manganese solution are computed in 200 cases for several solution concentrations. The results are evaluated by an auxiliary tool. Consideration of nuclear data uncertainty in calculations is a general trend that requires the attention of nuclear researchers and should draw attention in metrology. Additional uncertainty, calculated in a range from 0.5 to 1.5% (one-sigma) based on H/Mn ratio, can be introduced to the overall uncertainty through the calculation of the correction factor in according to the used nuclear data library and computational system.
