Scarabée

Scarabée is a simplified lattice physics code for light water reactor (LWR) neutronics calculations. It currently has the following features:

• Resonance self-shielding according to Carlvik's 2-term rational approximation
• 1D Annular pin cell collision probabilities solver for fixed-source and k-eigenvalue problems
• 2D Method of characteristics solver for fixed-source and k-eigenvalue problems
• Finite difference diffusion solver for 1D, 2D, and 3D fixed-source and k-eigenvalue problems
• Nodal expansion method diffusion solver for 3D k-eigenvalue problems
• PWR lattice calculations with depletion

This project closely follows the methods outlined in Methods of Steady-State Reactor Physics in Nuclear Design by Stamm'ler and Abbate, and Lattice Physics Computations by Knott and Yamamoto, from the Handbook of Nuclear Engineering, edited by D. Cacuci, and Applied Reactor Physics by Hébert.

Scarabée uses a custom HDF5 formated nuclear data library which is easy and intuitive to understand. The data directory contains a helper library and scripts to generate a multi-group nuclear data library with the FRENDY nuclear data processing code. FRENDY is free/open-source software, and can be downloaded here. Currently, only FRENDY is supported, due to its advanced multi-group processing features.
