%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%

In 1995, updated ORIGEN-S cross-section libraries were created as part of a program to upgrade and standardize the computer codes and nuclear data employed for used fuel characterization.  This effort was funded through collaboration between Atomic Energy of Canada Limited and the Canadian Nuclear Power Utilities, under the CANDU Owners Group (COG).  The updated cross sections were generated using the WIMS-AECL lattice code and ENDF/B-V and -VI based data to provide cross section consistency with reactor physics codes.

APPLICATION OF THE DATA -

The libraries in this data collection are designed for characteriting used fuel from CANDU pressurized heavy water reactors.  Two libraries are provided:  one for the standard 28-element fuel bundle design, the other for the 37-element fuel bundle design.  Thelibraries were generated for typical reactor operating conditions.  The libraries are designed for use with the ORIGEN-S isotope generation and depletion code.

4. METHODS

The CANDU libraries are updated with cross sections from a variety of different sources.  Capture and fission cross sections were obtained from collapsed 89-group ENDF/B-V and -VI data from the WIMS-AECL lattice code.  Other reaction cross sections were obtained from the SCALE 27-group ENDF/B-IV data.  In all, cross sections for more than 200 important actinides and fission products were updated with burnup-dependent data.  The source of the nuclear decay data and cross sections not updated were the base ORIGEN-S libraries distributed with the SCALE 4.2 code package.

The burnup-dependent cross sections were generated using eight burnup intervals that extend up to a burnup of approximately 12000 MWd/MgU.  The cross sections for each interval are stored in positions on the ORIGEN-S library and are accessed by referencing the position number.  The burnup values associated with each position are listed below.  They are the same for both the 37-element and 28-element libraries.

11. HARDWARE REQUIREMENTS

The libraries are distributed in a card-image format for platform compatibility.  They must be converted to binary library format using the OSBICO utility of SCALE. (See example of input included in the REAME file).
