Preliminary study on modeling the Dalat nuclear research reactor and generating the multi-group cross-section for three dimensional reactor kinetics calculations

In this paper, the Da Lat Nuclear Research Reactor (DNRR) core has been modeled by SCALE/TRITON code to generate two-group homogenized cross-sections for 3D kinetics calculations. In the calculation, plate-type model has been applied in selfshielding structure while the fuel assemblies have been grouped for the cross-section generation.
