This paper will focus on the calculations of the HTR-10’s first criticality. Continuous energy Monte Carlo transport code TRIPOLI-4.3, was used for getting the initial fuel loading of the HTR-10. The calculations have been performed on the basis of different treatment of the particles and the pebbles arrangement. The stochastic distribution of the particles in the fuel zone has been simulated, either using point-wise cross-sections associated with cubic or hexagonal lattices or using multi-group cross-sections provided by 1-D spherical transport calculation (APOLLO2 code). Different types of pebble arrangements have also been compared. Cross comparisons of the different hypotheses have been analysed including the impact of the libraries (JEF2 and ENDF/B-VI) and the estimation of the certain homogenisation effects. Therefore, this paper gives information related to the treatment of stochastic geometry in Pebble Bed Reactor (PBR) with the Monte Carlo method.
