Abstract
For the much detailed study of the beam transients on an Accelerator-Driven System (ADS), the 3-dimensional deterministic transport calculation mode for ADS dynamics calculation code is developed. The transport calculation mode is validated by the comparison with the benchmark problem published by OECD/NEA. The transport calculation and the diffusion calculation are compared by analyzing the ADS core with the use of the 3-dimensional deterministic transport calculation modes and the diffusion calculation mode equipped with ADS dynamic calculation code to reveal the effect of the transport calculation. As a result, the transport calculations show the larger fluxes than those by the diffusion calculation. The strong anisotropic fluxes are found to yield the significant effect on the flux calculations, and the influence of the anisotropy is increased by the abnormal beam condition. Therefore, the application of the transport calculation is very important for the precise evaluation of an ADS.
