Abstract: To improve the evaluation method, the EMPIRE was employed to analyze n+²³⁸U reaction up to 30 MeV. According to the special characteristics of neutron induced reaction of actinide nuclei, and chosing proper reaction mechanisms, the model parameters were adjusted and reasonable neutron reaction data were obtained based on the experimental data. Comparing the EMPIRE calculation results with the data of evaluations and measurements, it is found that EMPIRE can obtain reasonable results for n+²³⁸U reaction up to 30 MeV.
