The HTR-10 reactor is an experimental Pebble Bed Reactor (PBR), where simulating the neutron flux is crucial due to the reactor's multiple advantages, including safety, high efficiency, and modularity. As a result, studying and researching such reactors is a significant focus for countries with nuclear technology, especially for commercialization. Since both the fuel and moderator are in the form of spherical pebbles and are randomly distributed in the core, accurately evaluating the neutron flux is vital. This evaluation involves calculating the minimum height required for the reactor’s criticality, based on the specific arrangement of fuel and moderator. In this study, a new method for arranging the fuel and moderator pellets, while maintaining a ratio of 43:57, has been proposed. The calculations were performed using the MCNP code. Helium gas was chosen as the coolant, and changes in reactivity due to the insertion of control rods were also calculated.
