After several months of effort and testing, RSICC graduate student, Ranjit Subramani has completed a long awaited and anticipated upgrade to the RSICC website. See http://www-rsicc.ornl.gov/rsicc.html. We are still trying to track down bad links, etc. If you encounter problems please contact firstname.lastname@example.org. Your comments are welcome.
Two new packages and two corrections were added to the computer code collection this month. One was a foreign contribution.
Oak Ridge National Laboratory, Oak Ridge, Tennessee, and Wisconsin Department of Natural Resources, Madison, Wisconsin, developed this integrated screening-level, soil compartment model designed to simultaneously model water transport, sediment transport, and pollutant fate. The package was updated with a minor correction to the source, and the executable was recreated with a newer compiler. SESOIL is a one-dimensional vertical transport model for the unsaturated soil zone. Only one compound at a time can be considered. The model is based on mass balance and equilibrium partitioning of the chemical between different phases (dissolved, sorbed, vapor, and pure). The SESOIL model was designed to perform long-term simulations of chemical transport and transformations in the soil and uses theoretically derived equations to represent water transport, sediment transport on the land surface, pollutant transformation, and migration of the pollutant to the atmosphere and groundwater. Climatic data, compartment geometry, and soil and chemical property data are the major components used in the equations.
SESOIL runs on IBM PC or compatible. The package includes a PC executable created on a Pentium 4 under Windows 2000 with the Compaq Visual Fortran Version 6.6 Update A compiler using default compiler options. The package is transmitted on CD in a self-extracting, compressed Windows file, which contains documentation, source code, sample input and output data, and a Windows executable. Reference: PUBL-SW-200-93 (Revision 1.6) (August 1994). Fortran 77; IBM PC and compatibles. (C00629IBMPC03).
Los Alamos National Laboratory, Los Alamos, New Mexico, contributed corrections for this general-purpose, Monte Carlo, N-Particle code system that can be used for neutron, photon, electron, or coupled neutron/photon/electron transport. The package was updated with document revisions, a patch file, the corrected source and new executables for Windows, Linux, and MAC OSX. The corrections fix the two major issues noted below and some installation issues.
1. Fixed error in surface area calculation that affects some surface area calculations and therefore affects surface tallies.
2. Fixed access violation error when using FIR5 tally with a F4 tally.
Appendix G of the MCNP5 report was revised to correct the mis-labeling of the fission product ZAID's for 235U, 239Pu, and others based on data from Lawrence Livermore National Laboratory (LLNL). The changes affect the neutron cross section Table G.2 pages G-21 through G-25.
The distribution masters were updated for RSICC package ID C00710MNYCP01. Users who received the initial MCNP5 release may download the patch and revised Appendix G pages from the RSICC announcement page or the developers' website: http://www-rsicc.ornl.gov/rsiccnew/announcements.htm
Patch & LA-UR-03-810: http://www-xdiv.lanl.gov/x5/MCNP/theresources.html
If you received the initial MCNP5 release and want the new executables, request them via email to email@example.com. We will send you all the updates (new executables, patch file, and the revised MCNP5 Volume 1 report) on a CD. You must include the complete mailing address to which you want the CD mailed. The updates are distributed in a 10MB Winzip file. If you prefer to receive the updates by email, note that in your email message.
The MCNP5 code package includes MCNP5DATA cross section data libraries and the Visual Editor (VISED). The Windows-based PC version of VISED can be used for interactively constructing & visualizing MCNP geometry. The package is distributed on two 80-min., 700MB CDs. One CD contains GNU compressed Unix tar files that can be read on Unix, Linux or MAC OSX. The other CD is for Windows users and installs the code and libraries in the same step-by-step automated fashion common to many Windows programs using InstallShield. Included are electronic reports, source codes, Linux, PC and MAC executables, data libraries, test problems, and installation scripts.

InDose runs only on personal computers. The Fortran 90 source is not included in this package. The included executables run under Windows or Linux. On Microsoft Windows machines, InDose was compiled by the author using Digital Fortran 5. RSICC tested the distributed executables on the following systems:
The package is transmitted on a CD which contains the executables, test cases, and data files in a GNU compressed tar file and in a self-extracting Windows file. No source files are included. Reference: SNRC 2979 (December 1999). Fortran 90; Personal Computer - Windows or Linux (C00720PC58600).
Pacific Northwest Laboratory, Richland, Washington, through the OECD NEA Data Bank, Issy-les-Moulineaux, France, contributed COBRA-SFS (Spent Fuel Storage), a code for thermal-hydraulic analysis of multi-assembly spent fuel storage and transportation systems. The code uses a lumped parameter finite difference approach to predict flow and temperature distributions in spent fuel storage systems and fuel assemblies under forced and natural convection heat transfer conditions. Derived from the COBRA family of codes, which were extensively evaluated against in-pile and out-of-pile data, COBRA-SFS retains all the important features of the COBRA codes for single phase fluid analysis, and extends the range application to include problems with two-dimensional radiative and three-dimensional conductive heat transfer. COBRA-SFS has been used to analyze various single- and multi-assembly spent fuel storage systems containing unconsolidated and consolidated fuel rods with a variety of fill media, including air, helium and vacuum.
The source files are included in this package; however, no executables are included. A Fortran 77 compiler is required on all computers. Hewlett-Packard and SGI require one subroutine in C, for the elapsed time calculation. COBRA-SFS has run on SGI R8000/R10000, IBM/ps2, INTELx86, IBM/unix, Sun SPARCstation, DEC stations, Cray with COS operating system, Cray with UNICOS system, HP-9000 workstation, and APPLE MAC-II/MPW workstation. Operating systems include: SGI IRIX 6.X, Sun OS, IBM aix, DEC VMS, Cray UNICOS, INTEL with Microsoft Windows(TM) /NT/95, Hewlett-Packard HP-UX 9.05, and MacIntosh OS 7.0. INTEL PCs need something equivalent to Microsoft's Power Fortran. COBRA-SFS Cycle3 was tested at RSICC on a Sun UltraSparc60 running SunOS 5.6 using f77 5.0, on a DEC 500 Alpha running Digital unix version 4.0D with f77 5.1-8, and on a Pentium II running Windows 95b with Digital Visual Fortran Compiler Version 6.0A. The package is transmitted as a Unix tar file and a self-extracting DOS file on a CD. The distribution files contain source files, an information file, test case input and output.

Monthly Code Focus
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. December's code focus is Fuel Cycle & Waste Management.
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.
Every attempt is made to ensure that the links provided in the Conference and Calendar sections of this newsletter are correct and live. However, the very nature of the web creates the possibility that the
links may become unavailable. In that case, please call or mail the contact provided. Below is a condensed list of the conferences only listed chronologically. More details (if available) are listed alphabetically following the table.
This workshop will be held at McGill University, Montreal, Canada, from May 3-5, 2004, and aims to bring together medical physicists and researchers to discuss development, clinical implementation and clinical evaluation of Monte Carlo treatment planning techniques in radiotherapy. The meeting will have both invited speakers and proffered contributions and is designed to have plenty of opportunity for informal and in-depth discussions.

The 1st International Symposium on Radionuclide Therapy and Radiopharmaceutical Dosimetry will take place in conjunction with the annual European Association of Nuclear Medicine (EANM) congress in Helsinki, Finland, September 4-8, 2004.
The format of the meeting has evolved from a series of seven interesting and important radiopharmaceutical and dosimetry symposia held approximately every 5 years since 1970, with distribution of published proceedings. The last meeting ("7th International Radiopharmaceutical Dosimetry Symposium") was held in Nashville, TN, USA in 2002.
As a separate track within the EANM congress this symposium will aim to bring together all disciplines concerned with radiopharmaceutical dosimetry and radionuclide therapy stimulating interdisciplinary scientific discussion.
The decisions of the scientific committee and the set-up of the program for Helsinki will be coordinated by the EANM Task Group on Dosimetry and EANM Therapy Committee. All organisational matters will be handled by the EANM.
A call for abstracts (also electronic) will go out in a few months, with authors notified of outcome in approximately May 2004. Contributors will be asked either to bring an electronic version of their manuscript to the meeting in September 2004 or to submit it within two months after the meeting; early plans are to have extended peer-reviewed abstracts published as a supplement to a journal.

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. More information on code versions and capabilities is available at MCNPX Workshops web site http://mcnpxworkshops .com.
