摘要：

This paper investigates the applicability of the current OSCAR-4 code system to simulate the ETRR-2 reactor. Various modelling approaches are applied to this benchmark, in order to quantify the capability of neutronic modelling in OSCAR-4. In particular, the modelling of the control rod calibration experiments poses challenges to the traditional deterministic calculational path and alternatives are investigated to address these shortcomings. Results indicate that an improved homogenization approach directly impacts on the accuracy of the full core diffusion solution.
