Published on 2 April 2021

Tripoli-4® is the fourth generation of the continuous-energy radiation transport Monte Carlo code developed by the Service d'Études des Réacteurs et de Mathématiques Appliquées (SERMA) at CEA/Saclay [1].

Tripoli-4® is devoted to shielding, reactor physics with depletion, criticality safety and nuclear instrumentation for both fission and fusion systems.

The code has been under development at CEA since the mid-60s, at the Fontenay-aux-Roses center first, then at the Saclay center. Version 4 has been developed starting from the mid 90s in C++, with a few parts in C and Fortran [2, 3, 4].

A concise description of the key features of the code is provided in the menu on the left.
