EPRI

The Electric Power Research Institute, Inc. (EPRI) was established in 1973 as an independent, nonprofit center for electricity and environmental research. EPRI sponsored development of RETRAN and VIPRE computer programs that are used to perform transient and steady-state thermal-hydraulic analysis of nuclear reactor systems and they remain the owner of these computer programs. They have licensed CSA with commercialization rights to sell "use licenses" and to organize the maintenance and support activities for the programs.

In cooperation with a number of RETRAN and VIPRE code users including utility, commercial, and research organizations, a RETRAN/VIPRE User Group (RVUG) has been organized to provide ongoing maintenance, support, and development for the RETRAN and VIPRE codes. CSA is the contractor that provides these services for the RVUG.
