100th Licensing Agreement signed for INL Software RELAP5-3D
Idaho National Laboratory’s Reactor Excursion and Leak Analysis Program5-3D (RELAP5-3D) reached a milestone this week when it signed its 100th active license agreement. The RELAP5-3D code is used primarily for analysis of potential accidents and transients in water-cooled nuclear power plants, and for analysis of advanced reactor systems.
Since it was first introduced in 1996, RELAP5-3D has become one of the most widely licensed software products within DOE. Use of the code has grown steadily, nearly doubling in the last five years, and continued growth is expected. Licensees, both international and domestic, include universities, government agencies, nuclear steam supply system providers and utilities with operating power plants.
RELAP5-3D sustains itself primarily with membership fees from the International RELAP Users Group (IRUG), which provides funding to continually upgrade and maintain this safety analysis code.
