RSICC will be moving into a new building about one block west of our
current location August 8th! We will be packing the full week before
and unpacking the full week after. Our computers are being moved, so the
website will be down for a day or so. We hope to be established with full
communications the week of August 18th. We ask your patience during
the move. We will update the website when everything is back up and running.
Roger Carter, 74, died on June 29, 2003 in Richland, Washington. Roger was a long time, active, and very valued member of the Nuclear Criticality Safety community. A list of his accomplishments and activities is too long to include here. Somewhat newer members might recognize his name as a member of the Criticality Safety Benchmark Evaluation Working Group and one of the authors of an older handbook, ARH-600. He attended the University of Oklahoma and Oklahoma State (A&M) receiving a Masters degree in Nuclear Physics in 1952 and from there was recruited by Hanford to work at the various reactors in Criticality Safety. He retired in March of 1989. Affiliations include membership in the American Nuclear Society, obtaining emeritus status. He was recognized as an authority and coauthored a criticality safety handbook. After retirement he became a consultant for Mohr & Associates in Richland and was sent to work for Lockheed Martin in Oak Ridge, Tennessee from 1989 to 1997. He returned to consult for Mohr & Associates until he was unable to work due to illness. He was preceded in death by one daughter. He is survived by his wife, Bobbi, and three sons.
Changes to the Computer Code and Data Collection
One newly frozen package and one modified version were added to the computer code collection this month. One new data package was also added.
Oak Ridge National Laboratory, Oak Ridge, Tennessee, contributed a newly frozen version of this multilevel multichannel R-matrix code. SAMMY was first released in 1980 for use in analysis of neutron-induced cross section data at the Oak Ridge Electron Linear Accelerator. SAMMY has evolved to the point where it is now in use around the world for analysis of many different types of data. With the incorporation of charged-particle capabilities, SAMMY is no longer limited to incident neutrons, but can also be used for incident protons or alpha particles (etc.); likewise, Coulomb exit channels can be included. Corrections for a wide variety of experimental conditions are available in the code: Doppler- and resolution broadening, multiple-scattering corrections for capture or reaction yields, normalizations and backgrounds, to name but a few. The fitting procedure is Bayes' method, and data and parameter covariance matrices are properly treated within the code. Pre- and post-processing capabilities are also available, including (but not limited to) connections with the Evaluated Nuclear Data Files. Though originally designed for use in the resolved resonance region, SAMMY also includes a treatment for data analysis in the unresolved resonance region. See the SAMMY home page http://www-rsicc.ornl.gov/RIAS/Sammy.htm and links from there to the SAMMY users' group.
SAMMY runs on IBM RS/6000, DEC Alpha computers under both Open/VMS and OSF1 operating systems, Sun UltraSparc, PC under RedHat Linux, and on PC running Windows using Compaq Visual Fortran. The package includes PC executables created on a Dell Dimension 4100 under Windows 2000 with Compaq Visual Fortran Professional Edition 6.6.B, so Windows users do not require a compiler. All Unix, Linux and VMS systems require a Fortran compiler to create executables. SAMMY runs on DEC Alpha under both OSF1 and OpenVMS. At RSICC, SAMMY-M6 was tested on the following machines:
IBM RS/6000 Model 270 running AIX 4.3.3 with XLF 7.1 and XLC 4.4
The package is distributed on CD which contains the referenced document
in PDF format and a compressed Unix tar file with the source code, Windows
executable files, tutorials, Unix and VMS scripts, and test cases. WinZIP
8.0 or newer is required to expand this file under Windows. Reference:
ORNL/TM-9179/R6 (May 2003). Fortran; DEC Alpha (Unix and VMS), IBM RS/6000,
SUN, PC (P00158MNYCP09).
Los Alamos National Laboratory contributed a modified version of this automated, multi-step Monte Carlo burnup code system to calculate coupled neutronic/isotopic results for nuclear systems. Monteburns is a fully automated tool that links the Monte Carlo transport code MCNP with the radioactive decay and burnup code ORIGEN2 or CINDER90. Some minor changes were made, but no new features were added in this release. Monteburns produces a large number of criticality and burnup results based on various material feed/removal specifications, power(s), and time intervals. The principle function is to transfer one-group cross-section and flux values from MCNP to ORIGEN2, and then transfer the resulting material compositions (after irradiation and/or decay) from ORIGEN2 back to MCNP in a repeated, cyclic fashion (a simple predictor-corrector method is used during this process).
Along with other minor improvements in MONTEBURNS Version 2, the option was added to use CINDER90 instead of ORIGEN2 as the depletion/decay part of the system. CINDER90 is a multi-group depletion code developed at LANL and is not currently available from RSICC. This MONTEBURNS release was tested with various combinations of CCC-715/MCNPX 2.4.0, CCC-710/MCNP5, CCC-700/MCNP4C, CCC-371/ORIGEN2.2, ORIGEN2.1 and CINDER90. Perl is required software and is not included in this distribution. MCNP, ORIGEN2, and CINDER90 are not included.
The code runs on Sun Solaris, HP Unix, and Windows NT or Linux systems.
Note that it does not run under Windows95 or 98. Although it has not yet
been fully tested and debugged on other systems, it was designed to work
on any PC or Unix machine and on a VMS system. The main part of the code
was written in Fortran 77; but the interface between MCNP, ORIGEN2, and
MONTEBURNS is a Perl script that runs the codes and processes intermediate
data. Reports: LA-UR-99-4999 (September 1999). Fortran 77 and Perl; Sun,
HP and PC Windows NT systems (P00455MNYCP02).
Lawrence Livermore National Laboratory, Livermore, California, contributed POINT 2003, a temperature-dependent, linearly interpolable, tabulated cross section library based on ENDF/B-VI, Release 8.
As distributed, the original evaluated data include cross sections represented in the form of a combination of resonance parameters and/or tabulated energy dependent cross sections, nominally at 0 Kelvin temperature. For use in applications, these ENDF/B-VI, Release 8 data were processed into the form of temperature-dependent cross sections at eight temperatures between 0 and 2100 Kelvin, in steps of 300 Kelvin. At each temperature the cross sections are tabulated and linearly interpolable in energy.
POINT2003 contains all of the evaluations in the ENDF/B-VI general purpose library, which contains evaluations for 328 materials (isotopes or naturally occurring elemental mixtures of isotopes). No special purpose ENDF/B-VI libraries, such as fission products, thermal scattering, or photon interaction data are included.
The majority of these evaluations are complete, in the sense that they include all cross sections over the energy range 10-5 eV to at least 20 MeV. However, the following are only partial evaluations that either only contain single reactions and no total cross section (Mg24, K41, Ti46, Ti47, Ti48, Ti50 and Ni59), or do not include energy-dependent cross sections above the resonance region (Ar40, Mo92, Mo98, Mo100, In115, Sn120, Sn122 and Sn124). The PSR-351/PREPRO2002 code system was used to process the ENDF/B data. Any codes which treat the ENDF/B-VI format can be used as data retrieval programs.
In this library each evaluation is stored as a separate file. The entire
library is in the computer independent ENDF/B-VI character format, which
allows the data to be easily transported between computers. The data are
approximately 1.6 gigabyte in size and are distributed on three CD's. Reference:
UCRL-ID-12776-Rev-2 (May 22, 2003). ASCII data; PC or workstation (D00218MNYCP00).
As years have gone by many different codes and applications have been sent to RSICC for stewardship. We currently have over 1700 analytical code and data packages and distribute as many each year to 73 countries in the world. To help 'categorize' each package, we have developed a database of 'Subject Categories' to attach applications to the packages at RSICC. Doing so requires investigation into each code package, user feedback from end use statements, and extensive RSICC staff experience and analysis so that we can deliver useful information each month on the 30 different categories we have identified thus far. Links to the package abstracts are embedded into the WWW version of the RSICC Newsletter. Feedback from our Newsletter community is very valuable so please direct your comments and/or suggestions to PDC@ORNL.GOV. Many packages in the RSICC code collection are in this subject category. A few are highlighted here for your review. This month's code focus is Nuclear Data Post-processor, Graphic Display, Curve Fitting.
RSICC attempts to keep its users/contributors advised of conferences, courses, and symposia in the field of radiation protection, transport, and shielding through this section of the newsletter. Should you be involved in the planning/organization of such events, feel free to send your announcements and calls for papers via email to FINCHSY@ornl.gov with "conferences" in the subject line by the 20th of each month. Please include the announcement in its native format as an attachment to the message. If the meeting is on a website, please include the url.

MCNPX is the LANL all-particle, all-energy (eV-TeV) Monte Carlo transport code based on MCNP4C, LAHET, CEM, etc. MCNPX has been in active development since 1995, sponsored by the particle accelerator community. It has now become an accepted tool for a broad range of applications by nuclear engineers, physicists, and scientists. The MCNPX development effort has expanded the use of the Los Alamos tools to applications such as APT, waste transmutation, accelerator shielding and health physics, particle beam cancer therapy, space shielding and cosmic ray analysis, single event effects in semiconductors, radiography, and more detailed analysis of the effects of light and heavy ions in matter. In addition, the entire functionality of MCNP4C is retained. New variance reduction and data analysis techniques, many adapted from high energy accelerator methodologies, have also been added, such as the extensive 'mesh tally' capability which allows up to 3-d plotting of particle tracks, fluence and fluence-derived quantities, energy deposition, next event estimator generation contributions and particle sources.
The workshops include hands-on instruction, generally on PC Windows machines. Subject to participant export approval for the MCNPX beta test team, participants will be able to access the Fortran-90 version of MCNPX 2.4, the LA150 (150 MeV) cross-section data for over 40 isotopes for incident neutrons and protons, and 12 for photonuclear interactions, and a notebook of viewgraphs.
Follow-up consultation for class participants will be provided.
Classes are taught by experienced MCNPX code developers and instructors.
