RELAP5-3D is the latest in the RELAP5 code series developed at 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 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 INL through membership in the International RELAP5 Users Group (IRUG).The code is currently configured to run on both Linux and Windows. Operating systems and compilers supported are:
Linux: OpenSUSE: 42.2 (x86_64)
Windows: Windows 7, SP1
Intel compiler designation
On Linux: Version 16.0.4
On Windows: Composer XE 2013, SP1, Update 2
