No. 388 March 1997

No one has learned the meaning of life until he has surrendered his ego to the service of his fellow man---Beran Wolfe

The Ecstasy of the Web and the Agony of Email

Last month this editor was challenged to perform an experiment. Assignment: notify subscribers with email when the current newsletter is posted to the web and ask for a response. The message was sent to 1625 subscribers. Of that number 908 replied; 315 were refused; and 402 yielded no response, which I interpret to mean that someone somewhere received the message. I spent approximately 13 days abusing my carpel tunnel to evaluate, investigate, and respond to all those messages.

The purpose was twofold. First, to let our regular readers know that the newsletter is available at our web site. Second, to check the accuracy of the email list. The registration form, which we periodically ask you to complete, is our primary source of information. Since the form is often completed by hand and faxed, the email address can be misinterpreted.

I don't expect to repeat this process again, so those with access to the web may wish to check occasionally for the most current issue. Several of you suggested that the newsletter be sent as an attachment. That won't happen for several reasons that make it impractical. It would tie up our local email server; not every email system can or is set up to receive attachments; and many users could not read the software version that would be attached.

At some point in the future, those with access to the world-wide web will be asked to drop their subscription for a hard copy of the newsletter. This will result in a considerable savings in reproduction and postal expenses. Our subscribers will benefit in several ways. New and revised codes and data libraries announced are linked to the abstracts, and I will include the uniform resource locator (url) for conferences and seminars if it is provided by the author.

I thank all those who took the time to respond.

CHANGES TO THE COMPUTER CODE COLLECTION

Two new codes systems were added to the code collection and an existing code package was modified.

CCC-547/DANTSYS 3.0

OP SYS: Unix Language: C, Fortran 77 Computers: Cray, WS Format: tar

Los Alamos National Laboratory contributed modifications to DANTSYS to correct a problem of overfilling a string (SITOP). The changes to subroutines PERR and TOLCM are available on diskette, via email or through the www. The RSICC master has been updated with these recommended changes. DANTSYS is a one-, two-, and three-dimensional, multigroup, discrete-ordinates transport code system, which includes five major codes: ONEDANT, TWODANT, TWOHEX, THREEDANT, and TWODANT-GQ.

DANTSYS runs on the following platforms: CRAY-YMP, Sun SparcStation IPX, IBM RS/6000, HP, and Silicon Graphics under Unix-based operating systems. A Fortran 77 compiler, a C-language preprocessor (cpp), a C-compiler, and GMAKE (GnuMake from Free Software Foundation) are required to install the package which is distributed on 1 CD, DC 6150 (150 MB) cartridge, 4-mm or 8-mm tape in compressed tar format. Reference: LA-12969-M (June 1995). Fortran 77 and C; Cray and workstations (C00547/MFMWS/01).

CCC-648/GENII-S 1.485

OP SYS: DOS Language: Fortran 77, Basic Computers: PC Format: DOS

Sandia National Laboratory, Albuquerque, New Mexico, contributed this environmental radiation dosimetry code system. GENII-S is the result of implementing CCC-601/GENII from Pacific Northwest Laboratory in the Sensitivity and UNcertainty analysis Shell (SUNS) to provide the capability to perform sensitivity and uncertainty analysis in one calculation, eliminating manual interfaces between the GENII code results and sensitivity and uncertainty analysis codes. The GENII portion of the GENII-S package contains the program developed to incorporate the internal dosimetry models recommended by the International Commission on Radiological Protection (ICRP) into the environmental pathway analysis models used at Hanford. GENII is a coupled system of seven programs and the associated data libraries that comprise the Hanford Dosimetry System (Generation II) to estimate potential radiation doses to individuals or populations from both routine and accidental releases of radionuclides to air or water and residual contamination from spills or decontamination operations. The programs in GENII-S analyze environmental contamination resulting from both far-field and near-field scenarios. The system can calculate annual dose, committed dose, and accumulated dose from acute and chronic releases from ground or elevated sources to air or water and from initial contamination of soil or surfaces and can evaluate exposure pathways including direct exposure via water, soil, air, inhalation and ingestion pathways. The original data released with the CCC-601/GENII package and the alternate data contributed by HEDL, which is intended to improve the treatment of decay chains for calculation of doses from contaminated soil allowed to decay for hundreds of years, are included.

Lahey F77L-EM/32 Vers. 5.01 and Microsoft QuickBASIC 4.0 were used to create the executables included in the package. GENII-S runs on Intel PC's under MS DOS 6.0 or in a DOS window of the Windows95 operating system. One DS/HD 3.5-in., 1.44MB diskette is required for transmittal. Reference: SAND91-0561 UC-721 (April 1993). Fortran 77 and Basic; IBM PC (C00648/IBMPC/00).

CCC-660/MCNP4B

OP SYS: many Language: Fortran 77, C Computers: many Format: Unix, DOS

Los Alamos National Laboratory, Los Alamos, New Mexico, contributed the MCNP4B code system which replaces CCC-200/MCNP4A. This is a general-purpose, continuous-energy, generalized geometry, time-dependent, coupled neutron-photon-electron Monte Carlo transport code system. In addition to hundreds of minor features and numerous corrections, major MCNP4B code enhancements include:

MCNP treats an arbitrary three-dimensional configuration of materials in geometric cells bounded by first- and second-degree surfaces and some special fourth-degree surfaces. Pointwise continuous-energy cross section data are used, although multigroup data may also be used. Fixed-source adjoint calculations may be made with the multigroup data option. For neutrons, all reactions in a particular cross-section evaluation are accounted for. Both free gas and S(, ) thermal treatments are used. Criticality sources as well as fixed and surface sources are available. For photons, the code takes account of incoherent and coherent scattering with and without electron binding effects, the possibility of fluorescent emission following photoelectric absorption, and absorption in pair production with local emission of annihilation radiation. A very general source and tally structure is available. The tallies have extensive statistical analysis of convergence. Rapid convergence is enabled by a wide variety of variance reduction methods. Energy ranges are 0-60 MeV for neutrons (data generally only available up to 20 MeV) and 1 keV - 1 GeV for photons and electrons.

MCNP4B includes a test library of cross sections for running the sample problems, but all cross sections are included in the new DLC-189/MCNPXS code package, which is distributed with the code and requires a separate software license. MCNP4B is operable on Cray computers under UNICOS using CFT77 6.0.4.1, IBM RS/6000 under AIX 3.2.5 and AIX 4.2, SunSparc under SOLARIS 2.4 using F77 4.0, DEC Alpha under Digital Unix V3.2, HP with HP F77 9.16, SGI under IRIX 4.0.2, VAX computers under VMS 5.9 and all computers in general with at least 150 megabytes of hard disk. Executable files for the PC version are provided for running on 32MB memory on either a Pentium or 80486 computer with a coprocessor. The PC executables included in the package were created with the Lahey Fortran F77L3-EM/32 version 5.2 compiler. They run in a DOS window of either Windows95 or WindowsNT 4.0. Compilation of MCNP under Unix requires both Fortran 77 and ANSI C standard compilers. PVM is required for multiprocessing on a cluster of workstations. Scripts are provided for installation on both PC and Unix systems. Included are the referenced documents and the source codes, test problems, executables, and installation scripts available in either compressed Unix or DOS files on cartridge tape or CD-ROM. The code and cross sections are not available via ftp. References: LA-12625-M (1997), LA-13181 (August 1996), and LA-13138 (April 1996). Fortran 77 and C; Unix workstations, Intel-based PC, Cray, and VAX (C00660/ALLCP/00).

CHANGES TO THE DATA LIBRARY COLLECTION

One new data library was added to the collection during the month.

DLC-189/MCNPXS

OP SYS: many Language: Computers: many Format: ASCII

Los Alamos National Laboratory, Los Alamos, New Mexico, contributed the new MCNPXS standard neutron, photon, and electron data libraries for use with MCNP4B. This release includes all of the X-TM supported neutron data libraries, the photon libraries MCPLIB1 and MCPLIB02, the electron library EL1, an updated XSDIR file, and an information file README. This release completely replaces previous RSICC releases DLC-105 and DLC-181, as well as the cross sections previously included with CCC-200/MCNP4A, and will be updated as new libraries become available.

Currently the neutron data library ENDF60 (based on ENDF/B-VI, up through and including release 2) is the default library for continuous-energy neutron transport. Additionally, the libraries MCPLIB02 and EL1, are the default libraries for photon and electron transport..

A wide variety of continuous-energy, discrete, multigroup, thermal and dosimetry neutron data libraries are available in this release. The continuous-energy neutron data libraries available include: ENDF601, RMCCS1, RMCCSA1, ENDF5U1, ENDF5P1, NEWXS1, ENDF5MT1, MISC5XS1, ENDL851, KIDMAN1, and 100XS1. The discrete neutron data libraries include: NEWXSD1, DRMCCS1, DRE51. The multigroup neutron data library is MGXSNP1, and the thermal S(, ) libraries are TMCCS1 and THERXS1. The neutron dosimetry libraries are 531DOS1, 532DOS1, and LLLDOS1. The photon transport libraries are MCPLIB1 and MCPLIB02, and the electron library is EL1. The photon and electron data libraries contain data for elements having Z<95.

The data library ENDF5MT1 contains data previously available in the library EPRIXS, along with the U600K data library. The data library MISC5XS contains corrected data for ENDF/B-V based Zr and the libraries previously known as IRNAT, MISCXS, ARKRC, TM169, GDT2GP, and T2DDC. None of these data libraries have been previously distributed through RSICC. All data libraries and files are in ASCII mode and can be used with MCNP4B on all computer platforms supported by the code. The package is distributed in either compressed Unix or DOS files on CD-ROM or cartridge tape.
