In order to optimize the radiation shielding of natural uranium repository, taking the design limit of the external dose rate of the shielding of natural uranium repository as the reference control objective, and on the basis of analyzing the accuracy of existing shielding calculation methods, Microshield software is used to optimize the radiation shielding calculation method of natural uranium repository, especially the source term model. This method is based on the single storage barrel source model, the influence of uranium daughter and the superposition of several storage barrels is mainly considered. The calculation results are close to the actual monitoring results, and the calculation method is reliable, which can provide effective support for the radiation shielding design scheme of natural uranium repository.
