No. 386                                                       January 1997

The secret of the true love of work is the hope of success in that work; not for the money reward, for the time spent, or for the skill exercised, but for the successful result in the accomplishment of the work itself.---Sidney A. Weltmer


The following is the text of the announcement made on January 29, 1997.

Acting Secretary of Energy Charles Curtis today renamed the Idaho National Engineering Laboratory (INEL) to the Idaho National Engineering and Environmental Laboratory (INEEL). "The name change reflects the new mission of the laboratory and its focus on the technical challenges related to the environment, on both a national and global scale," said Acting Secretary Curtis. "The modification also acknowledges the role the Office of Environmental Management wants the Idaho National Engineering and Environmental Laboratory to play within the Department of Energy," said Alvin Alm, Assistant Secretary for Environmental Management. While the name change emphasizes the environmental mission of the laboratory, it will continue to service traditional engineering and applied research customers.


Two changes were made to the computer code collection during the month. Two existing code packages were updated to make corrections or to add new data. One contribution came from Japan.



Language: Fortran 77

Computers: FACOM

Format: tar

The Japan Atomic Energy Research Institute and the Research Organization for Information Science and Technology, Tokai-mura, Naka-gun, Japan, enhanced this package by adding the BERMJ3G data library and modifying some of the included codes. BERMUDA consists of nine codes to solve the time-independent transport equation for a given fixed source in a variety of geometries. A new 41 group constants gamma-ray library of 30 nuclides based on JENDL 3.2 was added to the package, and three codes for gamma-ray transport calculations were modified in this shielding analysis code system for use with both fusion and fission reactors. BERMUDA is written in Fortran 77 and runs on Facom/VP2600 computers. References: JAERI 1327 (May 1992), JAERI-M 93-143 (July 1993), JAERI 94-002 (July 1994), JAERI 95-006 (1995), and JAERI 96-021.

Oak Ridge National Laboratory contributed some minor corrections to this code system for simulating atomic collisions in crystalline targets using the binary collision approximation. The new release is designated Version 14b and corrects an error in handling thermal displacements in situations where atoms with a certain identifying number are on sites with a different identifying number. Users of MARLOWE version 14 may request details of the changes from RSICC.

The system executes on IBM MVS, VAX VMS, Data General, MS-DOS and a variety of Unix systems (AIX, DG/UX, EP/IX, HP-UX, IRIX, DEC Unix, SunOS, Ultrix, and Unicos.) MARLOWE runs on personal computers under Microsoft DOS, version 6 using the Lahey Fortran 90 compiler Version 1.10h. Source, scripts, test problems, and documentation files are included in the package. No executables are included in this package, which is transmitted either on one DS/HD 3.5-in. (1.44 MB) diskette in self-extracting compressed DOS files or on one diskette in a compressed tar file. References: Unpublished report (1996), Phys. Rev. B 40, (1989), Nucl. Instrum. Methods in Phys.

One addition was made to the data library collection during the month.




Computers: all

Format: UNIX, tar

ORNL contributed a new multigroup cross-section library based on ENDF/B-VI data produced and tested for light water reactor shielding and reactor pressure vessel dosimetry applications. This fine-group library, which is designated VITAMIN-B6, contains 120 nuclides. Several dosimetry response functions and kerma factors for all 120 nuclides are also included with the library. Significant benchmark data testing of VITAMIN-B6 was an integral part of this development work to accelerate the qualification. Over 50 benchmarks were calculated using the VITAMIN-B6 library. In general, results using the new data show significant improvements relative to earlier ENDF data.

The calculational approach for developing this new ENDF/B-VI library was consistent with the ANS 6.1.2 standard and is based on the successful development and application of the VITAMIN-C and VITAMIN-E pseudo problem-independent, fine-group cross-section libraries. The primary cross-section processing was performed by the modular PSR-355/NJOY94 system with RECONR, BROADR, THERMR, UNRESR, GROUPR, and GAMINR playing major roles. The SMILER module from AMPX77 was used to translate the intermediate NJOY file named GENDF into the AMPX master library format.

The data are in AMPX master library format which can be used with the CCC-545/SCALE system. PSR-352/SCAMPI was used to execute the two included test cases on an IBM RS/6000 workstation. Selected modules from the AMPX77 system can be used to perform the manipulations necessary to make problem-dependent working libraries for ANISN, DORT, TORT, MORSE, and other multigroup radiation transport codes. One CD-ROM or cartridge tape is required for transmittal of the package which is distributed as a compressed Unix tar file.

In serving a specialized area of scientific endeavor, it seems important that we note significant events or changes in the activities of people concerned with radiation protection, transport, and shielding in the nuclear industry. We, therefore, continue to carry personal items as they are brought to our attention.

ANS Elects Five New Fellows

The American Nuclear Society recognized five new fellows during the 1996 Honors and Awards Luncheon at the 1996 Winter Meeting. The new fellows and their citations are noted below:

Elizabeth "Libby" Johnson, ANS Charter Member, Dies at Home in Oak Ridge, Tenn.

It is with great sadness that we note the death of Elizabeth "Libby" Johnson, 75, on October 10, 1996, after a lengthy illness. Ms. Johnson was a charter member of the American Nuclear Society, an ANS Fellow, chaired the Nuclear Criticality Safety Division, served on the Standards Committee as a member and secretary on both the N16 consensus committee and subcommittee ANS-8, and was a member of several committees. Ms. Johnson worked on the Manhattan Project during World War II and worked for ORNL from 1946 until her retirement in 1994. She also served as an administrative judge on the U. S. Nuclear Regulatory Commission's Atomic Safety and Licensing Board Panel from 1975 to 1994.
