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 [23, 4].

The current official release is version 11.1, released in December 2020.
