RSICC CODE PACKAGE CCC-703

 

1.   NAME AND TITLE

ORIGEN-JENDL32:      Isotope Generation and Depletion Code with Libraries based on JENDL 3.2.

CCC-834/SCALE 6.2.1 with the latest version of ORIGEN is generally recommended for new ORIGEN users.

 

2.   CONTRIBUTORS

Tokai Research Establishment, Japan Atomic Energy Research Institute, Tokai-mura, Ibaraki-ken, and the O-arai Engineering Center, Japan Nuclear Cycle Development Institute, O-arai-machi, Ibaraki-ken, JAPAN, through the OECD NEA Data Bank in France.

 

3.   CODING LANGUAGE AND COMPUTER

Fortran 77; DEC Alpha, Sun, Linux (C00703MNYWS00).

 

4.   NATURE OF PROBLEM SOLVED

ORIGEN-JENDL32 includes a modified version of the CCC-371/ORIGEN2.1 code along with the libraries from that package plus new libraries, which are based on current reactor designs using the newest nuclear data file developed in Japan, JENDL-3.2. The new libraries contain not only one-group cross section data but also variable actinide cross sections and decay and fission yield data. Main objectives of the libraries are to calculate isotopic compositions averaged over whole fuel assemblies for the case of LWR and isotopic compositions averaged over a whole core for the case of FBR. Target fuel assemblies are PWR 17´17 type and BWR 8´8 or 9´9 type. Target core and blanket types of FBR are chosen from several considered specifications.  Evaluation of the LWR libraries was conducted by the analysis of latest post irradiation examinations carried out in Japan Atomic Energy Research Institute. The evaluation showed improved results of many isotopes. Evaluation of the FBR libraries was carried out by the comparison between new and old libraries of FBR. The calculated weights of several isotopes presented large differences.

ORIGEN is a computer code system for calculating the buildup, decay, and processing of radioactive materials. ORIGEN2.1 is a revised version of CCC-217/ORIGEN and incorporates updates of the reactor models, cross sections, fission product yields, decay data, and decay photon data, as well as the source code. ORIGEN2.1 includes libraries for standard and extended-burnup PWR and BWR calculations, which are documented in ORNL/TM-11018.  Note that new ORIGEN users are generally advised to request the CCC-834/SCALE 6.2.1 package, which contains ORIGEN and control modules to run it, in addition to a newer selection of data libraries.

 

5.   METHOD OF SOLUTION

ORIGEN uses a matrix exponential method to solve a large system of coupled, linear, first-order ordinary differential equations with constant coefficients.  See the Readme.txt file or the RSICC “tapelist” for a table which shows a list of libraries in the ORLIBJ32.

 

6.   RESTRICTIONS OR LIMITATIONS

No detailed documentation for guiding a novice user is provided.

 

7.   TYPICAL RUNNING TIME

In this package, the sample problems for 24 LWR libraries are archived. On Dell Dimension XPS T550 (equipped Pentium‑III 550MHz, 128 M‑byte memory) under Red Hat Linux 5.2(J), about 60 seconds is required to finish 24 sample problems.

8.   COMPUTER HARDWARE REQUIREMENTS

ORIGEN-JENDL32 runs on Sun, Compaq Alpha, and PC under Unix or Linux operating systems. To use the set of libraries, about 80 M byte free disk space will be required.

 

9.   COMPUTER SOFTWARE REQUIREMENTS

A Fortran 77 compiler is required to compile the code; no executables are included. The code was compiled at RSICC under Solaris 2.6, but test cases were not run.  The Japanese developers ran the code on several Unix systems:

Sun  Sparc under Sun OS4.1.4 and Solaris 2.5.1, 2.6 and 7

Dell PowerEdge 2300 PC Server under BSD/OS 4.0.1 and 4.1

Dell Dimension XPS T550 PC under Red Hat Linux 5.2(J)

Compaq Alpha under Tru64 UNIX V5.0
