OBITUARIES

The shielding community was saddened to learn of the passing of John L. "Kampy" Kamphouse on December 3, 2000. Kampy had served as the chairman of two teams that revised and reaffirmed two major radiation protection and shielding standards: ANS-6.4-1997 (Revision of ANSI/ANS-6.4-1985) - Nuclear Analysis and Design of Concrete Radiation Shielding for Nuclear Power Plants and ANS-6.4.2-1985; R1997 - Specification for Radiation Shielding Materials. Kampy had been a lead shield engineer at Gilbert/Commonwealth Engineers before coming to serve as a senior nuclear engineer for shielding and dose analysis for TVA's Brown Ferry's Nuclear Power stations from which he retired. He was also the dean of Bethel Bible College and had earned a doctoral degree in sacred theology and religion from Bethany Seminary in Dothan, Alabama. He will be greatly missed. RSICC apologizes for this late announcement.
 

Dr. Dixon Callihan, a resident of Oak Ridge, Tennessee, for 48 years before moving to Davidson, North Carolina in 1993, died after a brief illness Sunday, December 9, 2001. Callihan was born July 10, 1908, in Scarbro, West Virginia. Dr. Callihan received his undergraduate degree from Marshall College, Huntington, West Virginia, Masters from Duke University, and Ph.D. in Physics from New York University. He was a Professor of Physics at New York University and then City College New York when, in 1941, he joined a group working with the Atomic Energy Research Project (Manhattan District Project) at Columbia University. He came to Oak Ridge in 1945 where he began a long career contributing to the many interrelated disciplines of nuclear energy. Dr. Callihan retired in 1973 from the Oak Ridge National Laboratory as associate director of the Neutron Physics Division and director of the Critical Experiments Facility, and he continued work as a consultant until 1993. He was a member of the Nuclear Standards board of the American National Standard Institute since its inception in 1957. He was editor of the American Nuclear Society's Journal of Nuclear Science and Engineering until 1983, and served as an administrative judge on the Atomic Safety & Licensing Board panel of the U.S. Nuclear Regulatory Commission until 1990. Dr. Callihan received the Distinguished Service Award from the American Nuclear Society in 1983 for his many significant contributions to the Society, especially his founding of the Nuclear Criticality Safety Division. He was presented with the ANS Standards Committee Service Award in 1988 for thirty years of service to the program and his participation in both national and international standards groups.

TESTING THE WATERS

The proposed courses, tutorials, etc. will be held depending on user interest and participation. For more information or support of this workshop please contact hatmakerna@ornl.gov or sartori@nea.fr.

Workshop/Tutorial (tentative) on AMPX-2000, the latest version of the AMPX cross-section processing system that is developed and maintained by the Oak Ridge National Laboratory (ORNL). AMPX-2000 processes nuclear data evaluations that conform to the Evaluated Nuclear Data File (ENDF/B) format specifications. AMPX-2000 has the capability to process ENDF/B formats through Version VI and generate continuous-energy or multigroup cross-section libraries for neutron and/or photon transport. The objective of the workshop is to introduce new and experienced users to AMPX-2000. The workshop consists of classroom instruction provided by the AMPX code developers with an emphasis on use of the code system to process nuclear data evaluations. The workshop will also provide the participants with the opportunity to use AMPX to process nuclear data evaluations. Upon completion of the workshop, participants will have an understanding of the code system and be able to use AMPX to process ENDF/B evaluations and generate cross-section data for use in radiation transport codes. The proposed Agenda for a 5-day Workshop/Tutorial follows:

Day 1 - The first day will provide an introduction to ENDF/B formats and concepts associated with cross-section data. Followed by an overview of the AMPX-2000 code system that will include a discussion of the modular design philosophy and special features associated with the code system. The history of its sponsorship, major releases, etc., will be covered. In addition, a comprehensive overview of the processing capabilities will be provided. Differences and similarities to the NJOY processing system will be reviewed as appropriate. The remaining part of the first day will be devoted to a description of the AMPX modules and procedures that are used to generate continuous-energy cross sections from ENDF/B evaluations. In addition, the AMPX modules and procedures for processing the ENDF/B collision kinematics data will be described in detail.

Day 2 - Classroom instruction for the second day will focus on the modules and procedures that are used to produce multigroup neutron and photon cross-section libraries. The morning session will emphasize the AMPX modules that relate to producing multigroup data (e.g., generating weighting spectra, resonance-parameter processing, thermal-data processing, etc.). Workshop participants will gain familiarity with the different types of data that are used to provide a multigroup dataset for transport calculations. The afternoon session will be devoted to "hands-on" exercises that emphasize the course material from the first two days of instruction. Participants will have the opportunity to prepare input for producing continuous-energy and multigroup data using AMPX-2000.

Day 3 - The third day will begin with a review of the classroom exercises from Day Two followed by additional discussions on multigroup library processing as needed. New AMPX capabilities for generating probability tables and covariance matrices will be discussed in the morning session. The afternoon session will be devoted to additional classroom exercises related to generating continuous-energy and multigroup data. In addition, workshop participants will have the opportunity to generate probability tables and process ENDF/B uncertainty data with AMPX-2000.

Day 4 - The fourth day will begin with a review of the sample problems of the preceding afternoon session followed by classroom instruction for the various resonance self-shielding treatments that are provided in the AMPX system. The material will build upon the information presented on Day Two and include discussions of modules and procedures that must be used to prepare the appropriate data to be used in the treatments. The afternoon session will provide classroom exercises that make use of the course material presented in the morning session.

Day 5 - The fifth day will provide a review of the problems that were investigated on Day Four. A discussion of various AMPX-2000 utility modules will be provided. AMPX-2000 produces data in a wide variety of formats and has the capability to interface with the NJOY code system. The material covered on Day Five will focus on the utility modules that are needed to perform specialized data manipulation tasks (e.g., convert data between NJOY and AMPX, compare data libraries, constructing and maintaining a special energy boundary library for group structures, procedures for constructing specialized 1/ES t functions, AMPX installation procedures for different computer platforms, etc).

Changes to the Computer Code and Data Collection

Two new packages were added to the computer code software and data collection; both are foreign contributions.

PSR-513/BOT3P1.0
OP SYS: Unix
Language: Fortran 77
Computers: IBM, RS/6000, Sun/DEC
Format: tar

The ENEA Nuclear Data Center, Bologna, Italy, through the OECD Nuclear Energy Agency Data Bank, Issy-Les Molineaux, France, contributed this code system for 2D- and 3D- mesh generation and graphical display of geometry and results for the DOORS deterministic transport codes. Bologna Transport Analysis Pre-Post-Processors (BOT3P) provide users of the DORT and TORT deterministic transport codes (CCC-650/DOORS-3.2) some useful diagnostic tools to prepare and check their input data files. These tools were conceived to be as general as possible for a large number of applications. They were designed to overcome some difficulties in the preparation of the geometrical model entries and of the fixed neutron source entries of the DORT/TORT input files for the shielding calculations of the VENUS-1 and VENUS-3 benchmark experiments, within the framework of the activities of the OECD/NEA Task Force on Computing Radiation Dose and Modeling of Radiation-Induced Degradation of Reactor Components (TFRDD). BOT3P consists of the following six independent programs:

RVARSCL: Reads DORT/TORT "VARSCL" sequential format files.
GGDM: Generates the geometric and material entries for DORT.
DDM: Plot program used as a DORT pre/post processor.
GGTM: Generates the geometric and material entries for TORT.
DTM2: 2D plot program used as a TORT pre/post processor.
DTM3: 3D plot program used as a TORT pre/post processor.

BOT3P programs run on DEC Alpha, Sun and IBM RS/6000 systems and are expected to run on most Unix workstations. The developer implemented BOT3P under the following UNIX systems:

DEC Alpha, OSF1 V4.0F, DIGITAL Fortran, Version 5.2;
IBM RS/6000, AIX 4.3.2, XLF 3.2.5;
Sun Ultra 5, Solaris8, Fortran 77 version 4.2.

BOT3P1.0 has not been implemented under Windows. Executables that were created at RSICC on a Pentium computer under RedHat Linux 7 with the Portland Group, Inc. compiler are included. A Fortran 77 compiler is required to compile the codes on all other computers. At RSICC, the codes were also tested on an IBM RS/6000 under AIX 4.2 with XLF 3.2.2.3. The RSCORS, Sandia National Laboratory subroutine library of graphical primitives, is required to install and run BOT. RSCORS is distributed with the CCC-650/DOORS3.2 package. The package is transmitted on a CD in a GNU compressed Unix tar file. The tar file contains the source files, test cases, implementation instructions, procedures, description of sample problem cases, and documentation.

PSR-514/VIEW-CXS
OP SYS: Windows
Language: Visual Basic
Computers: Pentium
Format: Self-extracting Windows

The Safety Research Institute, Atomic Energy Regulatory Board, IGCAR Campus, Tamilnadu, India, contributed this interactive, user-friendly code system to graphically view neutron and gamma-ray cross-sections of isotopes, which are available in different data libraries. The names of isotopes for which the cross-sections are available is shown in a data base grid on the selection of a particular library. Routines have been developed in Visual Basic 6.0 to retrieve required information from each of the binary files or random access files. The present program can fetch data from:

1) ACE random access file used with MCNP code,
2) AMPX binary file used with KENO code,
3) ANISN group cross-sections used with discrete ordinate codes.

It is possible to compare the data of cross-sections for any isotope from selected libraries, and it is possible to extract a particular nuclear reaction cross-section from ACE library files. Context sensitive help is an attractive feature of the program and aids the novice user to extract the required data. Routines were developed to fetch the required data from binary (random access) files.

The interactive program was developed on a Pentium computer under Windows-95,98 and was tested at RSICC on a PENTIUM III 1GHz Micron running Windows 2000. The package is transmitted on a CD which contains a self-extracting compressed file that contains Visual Basic 6 source files, executable files, typical cross section library files and documentation and help files.

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.

All 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.
