Revision, extension and validation of the original RIPL-1 Starter File to produce a consistent RIPL-2 library of recommended input parameters. Electronic Starter File (known as Reference Input Parameter Library-1) was developed and made available to users throughout the world in 1997 (compilation) 1998-2003: RIPL-2 database (http://www-nds.iaea.org/RIPL-2/)http://www-nds.iaea.org/RIPL-2/ Main goal: Energy applications, E<20MeV

RIPL-4 hopefully will contain SMMC level densities The RIPL-3 database represents considerable advancements in the adoption and use of evaluated and highly credible nuclear data both for energy and non-energy applications One of the most significant database developments have involved important advances in the evolution of a complete and consistent set of input parameters for the calculation of a wide range of nuclear reactions. Efforts will continue to develop this database further, and monitor all studies that impact and could possibly improve their contents.
