Welcome to the RELAP5-3D^© Homepage.  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). For more information, select one of the upper buttons on the left.

 

RELAP5-3D^© News

• Three reports describing the use of PVM (Parallel Virtual Machine) to couple RELAP5-3D^© to other simulation codes are now available. The first report describes the API Application Programming Interface) for the coupling system. The second report describes the PVMEXEC program that initiates and controls a coupled simulation, and the third report describes the implementation of the coupling API in RELAP5-3D^©. These reports are not intended to provide enough information for a programmer to alter a simulation code so that it can be coupled to RELAP5-3D^© using the PVM coupling system described in the reports.
• The Idaho National Laboratory (INL) host the 2006 RELAP5 International Users Seminar at the Holiday Inn Sunspree Resort, West Yellowstone,Montana on August 16-18,2006.
• A set of RELAP5-3D^© training videos has been prepared. To find out more, click here.
