Abstract

A code called UNÌC is currently under development at Argonne National Laboratory (ANL). The aim of the code is to provide a neutronic solver with the same geometrical flexibility of Monte Carlo codes and without the approximations (homogenization and energy condensation) associated with the common multi-step approach currently used. Moreover, UNÌC will offer the capability of multi-resolution in phase space. At the moment, two methodologies are implemented: a second order spherical harmonics (P N) form of the transport equation and the first order method of characteristics.
