RELAP5-3D is the latest in the RELAP5 code series developed at the Idaho National Laboratory (INL) for the analysis of transients and accidents in water-cooled nuclear power plants and related systems as well as the analysis of advanced reactor designs.

The RELAP5-3D code is an outgrowth of the one-dimensional RELAP5/MOD3 code developed at the INL.  The most prominent attribute that distinguishes RELAP5-3D from its predecessors is the fully integrated, multi-dimensional thermal-hydraulic and kinetic modeling capability.

RELAP5-3D is available from the INL through membership in the International RELAP5 Users Group (IRUG).

Release of RELAP5-3D Version 4.0.3

The RELAP5 Team is pleased to announce that RELAP5-3D Version 4.0.3 is now available.

The development of this version has been a multi-year effort and the entire RELAP5 Team of George Mesina, Nolan Andersons, Cliff Davis, Hope Forsmann, Paul Bayless, Peter Cebull, Aaron Epiney, and led by Jim Wolf are to be commended for their dedication and the technical achievements they have accomplished.

The many new features and capabilities that have been added to the code for this release along with the current licensing and royalty strategy will insure that RELAP5-3D will remain the world’s leading reactor systems safety analysis code for many years to come.
