The scattering kernel, namely the energy and angle in which an emitted neutron is being scattered from nuclei with which it had interacted appears explicitly within the transport equation and hence emphasizes its huge importance for any reactor calculation. In particular, the growing attention on the final disposal restrictions calls for an exact analysis on the spent fuel inventory, where the scattering kernel can change significantly the nuclei inventory vector.

The objective of the work is to exchange the approximated scattering kernel treatment in the transport code MCNP by an accurate scattering kernel method known as DBRC.  By employing the burn up code CINDER, the modified nuclear vector of several burn up subassemblies will be calculated for various type of fuel-rods used in Light water reactor as well as in boiling water reactors.

This work permits the Student to gain a detailed insight into the state-of-art of computational reactor Physics, within an international project, in view of the planned nuclear waste repositories.
