The ORIGEN2 computer code was developed by Oak Ridge National Laboratory (ORNL) in the late 1970s and made available to users worldwide in 1980 through the Radiation Shielding Information Center (RSIC). The purpose of ORIGEN2 is to calculate the buildup, decay, and processing of radioactive materials. Since 1980, more than 500 users have acquired the ORIGEN2 code from RSIC. ORIGEN2 is often the starting point for many analyses involving the shielding, criticality, safety, performance assessment, accident analysis, risk assessment, and design of reactors, transportation casks, reprocessing plants, and waste disposal facilities. An updated version of the ORIGEN2 code package has been prepared by ORNL. This new version of the ORIGEN2 package (called ORIGEN2, Version 2.1 (8-1-91)) includes revised ORIGEN2 cross-section libraries for standard- and extended-burnup pressurized-water and boiling-water reactors (PWRs and BWRs). These libraries were used in the preparation of Revision 1 of the Characteristic Data Base (CDB). The ORIGEN2 code has also been revised to include numerous maintenance fixes and to consolidate various hardware versions into a single source code capable of execution of both 80386/80486 PCs as well as most mainframe computers; these improvements are part of Version 2.1.
