Abstract: | The C5G7 MOX benchmark was proposed to test the ability of commercial transport codes to treat reactor core problems without spatial homogenization. The benchmark requires solutions in the form of normalized pin powers as well as the eigenvalue. In the work, the two-dimensional benchmark calculation using the TWODANT code within the DANTSYS code package has been performed with proper spatial and angular approximations. The TWODANT code solves the multigroup discrete ordinates form of the Boltzmann transport equation in two-dimensional geometry. The calculation results show a good agreement in comparison with the reference solution obtained from a seven-group MCNP calculation. In addition, sensitivity studies on mesh and angular refinements have been performed to produce a higher quality solution. In the results, it is found that in the TWODANT calculation the spatial approximation in a staircase form of the circular fuel pin with relatively high quadrature order of SN is a viable method for solving the2-D C5G7 benchmark. |
