In order to verify the accuracy of the shielded benchmark questions and further improve the standard benchmark question bank in China, this paper adopts MCNP fine modeling and calculation method to evaluate and verify the accuracy of 3 representative benchmark questions in the SINBAD shielded benchmark question bank. Combined with the experimental results of the literature, it is shown that the simulation results can provide the data verification support to other independent software within the allowable error range, and the verification result...
