Thought is the first faculty of man; to express it is one of his first desires; to spread it, his dearest privilege.---Abbé Raynal

CD-ROM Availability

When RSIC announced the availability of CD-ROMs for the transfer of codes/data libraries several months ago, the medium was readily available. However, with the great popularity of this medium for multi-media computing systems marketed for the private sector, this is no longer true. Distribution and manufacturing facilities have not caught up with the demand, and RSIC has been caught in the crunch of back orders and shortages. Until further notice we ask that clients who prefer their software be distributed on CD-ROM send a blank CD with the request. Currently, we can use a 74-minute (650 MB) writable CD-ROM. If you send a used CD, indicate whether you want the last track overwritten and be aware that your equipment must be able to handle multi-sessions.

CHANGES TO THE COMPUTER CODE COLLECTION

Five changes were made to the computer code collection during the month. Two existing code packages were replaced with newly frozen versions, and three code packages were improved with updated software to facilitate execution.

CCC-200/MCNP4A

OP SYS: UNIX, DOS, VMS
Language: Fortran 77
Computers: Many
Format: DOS, tar
This general purpose Monte Carlo code system for calculating the time-dependent continuous-energy transport of neutrons, photons, and/or electrons in three-dimensional geometries was updated with the addition of a new executable for personal computers which will allow execution of large problems. In the new file the MDAS parameter is 6,000,000 and requires 32 MB of memory. Users who already have the code package may request the one diskette on which this executable is written.
MCNP4A is available on either CD-ROM or cartridge tape in compressed UNIX tar format or in a self-extracting compressed DOS file. It is also available on 30, 3.5-in. DS/HD (1.44 MB) diskettes. In addition to the source files, executables created on a PC 486 using the Lahey Fortran F77L-EM/32 Version 5.10 compiler under DOS 6.0 are included. The executables also run under Windows95. References: LA-12625 (1993), LA-12212, LA-12827-M and Nucl. Sci. Eng. 116: 269-277 (1994). Fortran 77 and C; UNIX workstations, PC 386, Cray, Vax, Sun, DEC, HP and SGI, mainframe and all computers in general; (C00200/ALLCP/04).
CCC-371/ORIGEN2.1

OP SYS: DOS
Language: Fortran 77
Computers: all
Format: DOS
Oak Ridge National Laboratory, Oak Ridge, Tennessee updated the ORIGEN2.1 code package by recreating the executable to allow it to run under Windows95. This isotope generation and depletion code uses the matrix exponential method to calculate the buildup, decay, and processing of radioactive materials. ORIGEN2 is a revised version of ORIGEN and incorporates updates of the reactor models, cross sections, fission product yields, decay data, and decay photon data. ORIGEN2.1 includes libraries for standard and extended-burnup PWR and BWR calculations.
In this update the PC source was compiled and linked with the Lahey F77L-EM/32 Fortran compiler Version 5.10 to eliminate incompatibility with the original executable created with Lahey F77L-EM/32 Version 4.0 when run under Windows95. No source modifications were necessary. ORIGEN2.1 runs on VAX/VMS and 386/486 PCs with at least 4 MB of extended memory and about 20 MB of hard disk and a math coprocessor. The same source runs on both systems, and conversion to other computers should not be difficult. The Fortran source and PC executable files are included in the package, which is transmitted on three 1.44 MB DS/HD 3.5-in. diskettes in self-extracting compressed DOS files. A Fortran compiler is required to run on mainframes. References: ORNL/TM-7175 (July 1980) and Nucl. Technol., 62, p 335 (September 1983). Fortran; VAX, PC 386/486 (C00371/ALLCP/01).
CCC-552/RESRAD 5.61

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

Argonne National Laboratory contributed a newly frozen version of this code system to calculate site-specific residual radioactive material guidelines and radiation dose and excess cancer risk to an on-site resident. Major improvements in Version 5.61 include the use of ICRP-38 data on radionuclide half-lives, correction of an error in the interface that may occur when FIND+FOUT=0, and correction of a typographical error in the Daughter Dose report. External dose is calculated for any size, depth, and shape of contaminated soil based on values listed in FGR 12.
The Lahey F77L-EM/32 and Microsoft Visual BASIC Version 1.0 compilers were used to create the executables included in the package. Note that the source files are not included. The package is distributed on one DS/HD 3.5-in. (1.44 MB) diskette in self-extracting compressed DOS files. Reference: ANL/EAD/LD-2 (Sept. 1993) and ANL/EAIS-8 (April 1993). Fortran 77 and BASIC; PC 386 or 486 (C00552/PC386/02).
CCC-650/DOORS3.1

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

Oak Ridge National Laboratory, Oak Ridge, Tennessee, contributed corrections to this one-, two- and three-dimensional discrete ordinates neutron/photon transport code system to facilitate execution on Cray computers. DOORS 3.1 includes the most recent versions of CCC-543/TORT-DORT, CCC-254/ANISN-ORNL, CCC-628/GBANISN and CCC-351/FALSTF. It also includes the ISOPLOT code from PSR-155/DOGS and various utility programs which were previously included in the TORT-DORT package: GIP, ALC, RTFLUM, BNDRYS, GRTUNCL, VISA, TORSED and TORSET. ISOPLOT was modified to use the Sandia National Laboratory RSCORS graphical system. Sandia National Laboratory's CMP system for code maintenance is used to build the Fortran source files for the target computer. Both RSCORS and CMP are distributed with the system.
TORT calculates the flux or fluence of particles due to particles incident upon the system from extraneous sources or generated internally as a result of interaction with the system in two- or three-dimensional geometric systems, and DORT is used in one- or two-dimensional geometric systems. The principle application is to the deep-penetration transport of neutrons and photons. Certain reactor eigenvalue problems can also be solved.
The modifications were necessary to build executables for ANISN, GBANISN, ISOPLOT, and FALSTF on Cray computers. Other systems were not affected. DOORS runs on Cray, IBM RS/6000, Sun, DEC Alpha, SGI, and Hewlett Packard systems under UNIX-based operating systems. Updates are available on one, 3.5-in (1.44 MB) diskette written in tar format.
The package is transmitted as a UNIX tar file written on either CD-ROM, QIC-150 (150 MB), 4-mm DAT (8 GB), or 8-mm (2.3 GB) cartridge tapes. The tar file contains the Fortran and C source files, test cases, implementation instructions, procedures, description of sample problem cases, and much of the referenced documentation.

PSR-355/NJOY 94.35

OP SYS: CTSS, UNICOS, UNIX
Language: Fortran 77
Computers: many
Format: tar

Los Alamos National Laboratory, Los Alamos, New Mexico, contributed a newly frozen version of this code system for producing pointwise and multigroup cross sections from ENDF/B evaluated nuclear data, including ENDF/B-VI. The new version, designated NJOY94.35, fixes problems found and corrected by updates 11-35, which involve changes to the acer, groupr, matxsr, njoy, broadr, dtfr, viewr, heatr, covr, leapr, and reconr modules.
The NJOY94.35 release is basically configured for UNIX. The test problem input files are UNIX shell scripts, and the test problem results are from runs on a Cray Y-MP8/4-64 running UNICOS. The code runs on Cray/UNICOS, Cray/CTSS, IBM, VAX/VMS, and Sun workstations and is transmitted on either 1 CD-ROM, DC 6150 (150 MB) cartridge, 4-mm, or 8-mm tape in tar format.

CONFERENCES, COURSES, SYMPOSIA

RSIC 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 raf@ornl.gov.

Practical MCNP for the Health Physicist

The Los Alamos MCNP code is a general and powerful Monte Carlo transport code for photons, neutrons, and electrons. It is now supported on a variety of platforms and can run on everything from a laptop to a workstation.

This course is aimed at the HP with little or no experience with Monte Carlo techniques. The focus is almost entirely on the application of MCNP to solve a variety of practical problems in radiation protection. The intent is to "jump start" the student toward using MCNP productively. Extensive practice sessions are planned on a DOS-based computer platform. Basic knowledge of DOS and the DOS text editor are desirable.

Topics will include:

Input file preparationInterpretation of output fileExposure and dose rate calculationsSkyshine calculationsNeutron transportDetector simulationPhoton shieldingElectron transport and x-ray production

Students will be provided with extensive class notes and a diskette containing all of the practice problems. Continuing Education Credits have been applied for with the Health Physics Society.

The course is offered by the Health Physics Measurements Group at the Los Alamos National Laboratory. For further technical information, please contact Dick Olsher, 505-667-3364, e-mail: dick@lanl.gov.

The course is 4.5 days in duration and will be offered on the following dates:
