Changes to the Computer Code and Data Collection

PSR-333/CHENDF 7.02

The National Nuclear Data Center, Brookhaven National Lab., Upton, New York, contributed a newly frozen version of this code system for handling ENDF/B-V and ENDF/B-VI data. Version 7.02 of the ENDF Utility Codes corrects all bugs reported to NNDC as of April 1, 2005, and supersedes all previous releases. It can process all ENDF-6 formats approved up to and including the November 2004 CSEWG meeting except for the Generalized R-Matrix resonance region format and the generalized format for covariances (file 30) and the new trial formats for resonance parameters and their covariances. The programs will also process ENDF-5 formatted files.

CHECKR format checking program

FIZCON procedures and simple physics checking program

INTER calculates selected cross sections and integrals

PSYCHE more complicated physics checking program

STANEF creates directory, adds tape label and converts numeric fields

The programs conform to the Fortran 95 standard and should operate on any computer with sufficient memory and a Fortran compiler conforming to this standard. The source files can be converted to run on various platforms by using the SETMDC code. Three codes CHECKR, STANEF, and INTER were actually ported from the 7.01 release without any change (therefore, they will identify themselves as 7.01 in the output).

NNDC provided executables that were created with Compaq Visual Fortran 6.6 for Windows and Lahey/Fujitsu Pro 6.2 for Linux. These are included in the package. The codes can be run in either batch or interactive mode.

The package is transmitted on a CD in a WinZip file which includes the source codes, executables, documentation and test cases. Reference: NNDC Informal report (May 31, 2005). Fortran 95; PC and workstations (P00333/MNYCP/05).

PSR-526/ERROR-J, Version 2.2

Sumitomo Atomic Energy Ind., LTD, Tokyo, Japan, and Japan Nuclear Cycle Development Institute, Ibaraki, Japan, contributed a newly frozen version of ERRORJ. In the new Version 2.2 release non-diagonal elements of covariance matrices are calculated in the resonance energy region. An option for high-speed calculation is implemented and the perturbation amount is optimized in a sensitivity calculation. The effect of the resonance self-shielding on covariance of multigroup cross sections can be considered.

ERRORJ produces multigroup covariance matrices from ENDF/B-6 format and is based mainly on the methods of the ERRORR module in NJOY94.105. Thus all the functions of ERRORR are available in ERRORJ. which produces a COVFIL format file to store multigroup covariance data which is then converted to a COVERX format file by the conversion program NJOYCOVX. A COVERX format is proposed as a standard file of multigroup covariance data in the FORSS system.

ERRORJ was developed on HP 9000/735 and was tested on DEC and Sun Unix workstations. A Fortran 77 compiler is required to compile the codes; no executables are included with the package. RSICC tested ERRORJ 2.2 on the following systems: DEC alpha using Compaq Fortran V5.5 1877-48BBF and Sun Sparc Station under Solaris 6.9 with Sun WorkShop 6 2000/04/07 Fortran 77 5.2. The package is distributed on a CD in a GNU compressed Unix tar file which includes source code, data files for sample cases, test input and output. References: JNC TJ 9440 99 003 and JNC TJ 9440 99 003 (1999) [English translation]. Fortran 77; HP, DEC Alpha, and Sun SparcStation (P00526MNYCP01).


The IAEA Nuclear Data Section, Vienna, Austria, contributed an updated version of FENDL-2 termed FENDL-2.1. All evaluated nuclear data files from FENDL/E-2.1 were processed for fusion applications using the NJOY-99.90 code system to create new FENDL/MC-2.1 and FENDL/MG-2.1 libraries.

FENDL/MC-2.1 contains continuous energy data files in ACE format (output of NJOY module ACER) for MCNP calculations. All the files were created at 300K and probability tables (PT) were generated for those materials with unresolved resonance data.

FENDL/MG-2.1 contains neutron-photon coupled multigroup cross section data in GENDF and MATXS formats (output of the NJOY modules GROUPR, GAMINR and MATXSR). These data can be easily processed by the code TRANXS (PSR-317/TRANSX 2.15) for further use in deterministic transport codes such as DANTSYS, ANISN, DORT and TORT. The Vitamin-J energy structure was used for neutrons as well as photons to give 175 energy groups between 0.00001 eV and 19.64 MeV for neutrons, and 42 groups between 1 keV and 50 MeV for photons.

The use of isotopic evaluations for Cl, Ti, Mo and W increases the number of materials from 57 in FENDL-2.0 to 71 in FENDL-2.1.

The ACEDOP code (SIGACE package), which is included in the distribution, allows Doppler broadening of resolved resonances in the ACE-formatted files except for the energy region described by unresolved resonance representation in the original ENDF-formatted files. For the sake of completeness, NJOY inputs to generate ACE, MATXS and GENDF files are supplied on the CD. The ASCII data libraries can be used on any computer platform and are distributed in ZIP files. References: INDC(NDS)-467 (December 2004) and INDC(NDS)-451 (November 2003). (D00222MNYCP00)

SCALE Source Terms and Shielding Course

The SCALE Source Terms and Shielding Course covers SAS2 and ORIGEN-ARP (depletion/
source-term generation), SAS1/XSDRNPM (1-D neutron/gamma shielding), SAS4/MORSE-SGC (3-D Monte Carlo neutron/gamma shielding), and QADS/QAD-CGGP (3-D point kernel gamma shielding). The course will feature the use of SCALE Windows GUIs: OrigenArp for Windows, ORIGEN-S plotting utility PlotOPUS, and the ESPN shielding input processor for SAS4.

KENO V.a Criticality Safety Course

The SCALE KENO V.a Criticality Course focuses on KENO V.a and associated criticality analysis sequences in CSAS. KENO V.a is a widely used 3-D multigroup Monte Carlo criticality safety code that has been in use for 20 years. It is a fast, easy-to-use code that allows one to build complex geometry models using basic geometrical bodies of cuboids, spheres, cylinders, hemispheres, and hemicylinders. Two-dimensional color plots of the geometry model can be generated in KENO V.a or the model may be viewed using the KENO3D 3-D visualization tool.

TSUNAMI Sensitivity/Uncertainty for Criticality Safety Course

Sensitivity coefficients produced by TSUNAMI sequences predict the relative changes in a systems calculated k-eff value due to changes in the neutron cross-section data. TSUNAMI produces sensitivity data on a groupwise basis for each region defined in the system model. First-order perturbation theory is used to compute sensitivity coefficients from both cross-section and flux data. TSUNAMI folds sensitivity data with cross-section covariance data to calculate the uncertainty in the calculated k-eff value due to tabulated uncertainties in cross-section data. The applicability of benchmark experiments to the criticality validation of a given application can be assessed using S/U-based integral indices that can quantify system similarity. Attendees must have attended a KENO course or be experienced KENO users.

This two-day training course on neutron spectra unfolding will be held April 78, 2006, in Cape Town, South Africa. The training course is organized by the Neutron Radiation department of the Physikalisch-Technische Bundesanstalt (PTB), Braunschweig, Germany. Additional support is provided by EURADOS. The course is intended for those who do spectrometry in neutron or mixed neutron/photon fields and need to analyze their data using unfolding procedures; emphasis is on practical aspects of unfolding.

A series of lectures in the morning sessions will provide an introduction to unfolding as well as allow for discussions on the theory of unfolding. In the afternoon sessions participants will work on specific examples at PC-workplaces using the UMG software package provided by PTB (UMG: Unfolding with GRAVEL and MAXED, currently distributed by NEA as code package NEA-1665 and by RSICC as code package PSR-529). We will focus on Bonner sphere measurements for our discussion of few-channel unfolding, and on liquid scintillation spectrometer (NE213) measurements for our discussion of multi-channel unfolding.

The number of participants will be restricted due to the limited number of PC-workplaces available. Therefore, you should register as soon as possible. For on-line registration and further information please visit the website at: http://www.ptb.de/utc2006/. Contact: Burkhard Wiegel, PTB, email Burkhard.Wiegel@ptb.de The fee for the course is 800 Euro and includes a CD with a complete set of notes and unfolding software, as well as refreshments.
