SARIS - In the Beginning

In the late '50s, science management was beginning to worry about the information "explosion" in which the scientist or the engineer working at his/her desk could not begin to keep up with the literature being published. The suggested solution was the information analysis center (IAC) where knowledgeable staff could review, evaluate, and select the best in a specialized field, package it and make it available where needed. A number of research institutions sought funding to establish such centers, mainly concerned with literature. It should be noted that at that time the detailed work of indexing and extracting of key information from selected literature specimens was manual. No existing information centers were using computers.

The Radiation Shielding Information Center (RSIC) was established at ORNL in FY 1963 by the United States Atomic Energy Commission (USAEC) to collect, organize and disseminate information on shielding against radiation from nuclear reactor and other low-energy radiation sources. The information initially was in the form of published literature and computer codes. The original staff consisted of three people: physicists S. Keith Penny and David. K. Trubey and mathematician-programmer, Betty F. Maskewitz. The latter was given the responsibility for establishing the computer codes and nuclear data activities. Penny and Trubey, assisted by Peggy Emmett as programmer, assumed the task of developing the literature system.

The computer-based Storage and Retrieval Information System (SARIS), programmed in Fortran, was the first of its kind. As RSIC's subject coverage extended to cover radiation from additional sources, i.e., radioisotopes, weapons, accelerators, and both natural and manmade radiation in space, additional staff members were called on to review literature for input to SARIS. Selected literature was announced in the RSIC Newsletter. The first broad dissemination was made by published documents, and these were considered useful by technical universities. In the early stages of research in radiation transport and shielding, the literature data base was considered to have considerable value. Prior to today's network facilities, a staff member devoted full time to managing the system, including special searches on demand with the results mailed to the customer. Each technical staff member devoted some time to reviewing and evaluating the literature to be included in the system.

With increasing capability of internet search engines and availability of scientific information on the web, usage of the SARIS database has been declining while the costs of updating and maintaining it are steadily increasing. For these reasons, RSICC is retiring the SARIS database. As of this edition, the SARIS portion of the Newsletter will be no more. We hope it has been a helpful service to you over the past 40 years.

In regards to "what set of data (is available | is best)??"

In a recent posting to the MCNP Forum, Morgan White of the MCNP data team sent some advice to aid users in selecting data sets to be used with MCNP. While his message applies specifically to ACE libraries, much of the background information can be useful to a more general audience.

The MCNP Forum entries are archived in the electronic notebook. Please view his comments on "what set of data (is available | is best)??" at http://rsicc.ornl.gov/cgi-bin/enote.pl?nb=mcnp5&action=view&page=385

The September 2004 Edition of the "International Handbook of Evaluated Criticality Safety Benchmark Experiments"

The September 2004 edition, of the "International Handbook of Evaluated Criticality Safety Benchmark Experiments" will be available for distribution on DVD near the end of September. Twenty-nine newly approved evaluations are included in this version in addition to all previously approved evaluations. A new volume, Volume VIII, entitled "Criticality Alarm / Shielding Benchmarks" has been added to the 2004 edition of the Handbook. Provided in this volume are benchmark specifications that are intended primarily for validation of calculational techniques used to determine the need for criticality alarms and placement of those alarms. Only one evaluation of this type is included, and it is included only as a DRAFT. This evaluation includes benchmark specifications for 6 labyrinth-type configurations with multiple measurement points for each. Two other evaluations of this type were prepared, but are not included because of time constraints. Publishing information in DRAFT form is not a common practice for the ICSBEP. However, in this case we are soliciting comments from the user community before including more of these types of benchmarks. Please forward any comments to bbb@inel.gov prior to January 31, 2005.

Changes to the Computer Code and Data Collection

CCC-430/EDMULT 6.4
OP SYS: Windows, Unix
Language: Fortran 77
Computers: PC, Workstation
Format: WinZIP

The Institute for Data Evaluation and Analysis, Sakai, Osaka, Japan, contributed a correction to EDMULT. Subroutine EDBREM was modified to eliminate a warning-level error when compiling. EDMULT evaluates depth dose distributions produced by plane parallel electron beams normally incident on one to six layer slab absorbers. EDMULT is based on an analytic expression of the depth dose curve in semi-infinite medium and a simple model of electron penetration through a multilayer absorber. The effect of the different medium beyond an interface is accounted for by the difference of backscattering, which is evaluated by considering the branching of electron beam into transmitted and backscattered components.

The code is operable on almost any computer with a Fortran compiler. The developer ran it on several computers including Macintosh with the Absoft compiler. An executable created with the Lahey F95 V5.60a compiler is included in the package for PC Windows users. This release was tested at RSICC on:

IBM RS/6000 Model 270 running AIX 4.3.3 with XL Fortran Version 7.1
Intel-Linux 7 with g77 under RedHat Linux 7
WindowsXP on Pentium IV with Compaq Visual Fortran 6.6B
WindowsXP on Pentium IV with Lahey 95 5.60a

EDMULT is transmitted on a CD with the document, source files, sample problem input and output, and a Windows PC executable in a WinZIP file. Reference: RCOP TR-8 (November 1987). Fortran 77; Intel PC, Workstations, MacIntosh (C00430MNYCP02).

OP SYS: Windows
Language: Fortran 77
Computers: Pentium
Format: WinZIP

North Carolina State University, Raleigh, North Carolina, contributed this Monte Carlo simulation code, which was developed to simulate pulse pile-up spectra for high counting rates from given true spectra. In this simulation, the exponential pulse interval distribution is used and the multichannel analyzer (MCA) is assumed to operate perfectly in obtaining and scoring the first local maximum from a sum pulse. Forcing and other variance reduction techniques are used to accelerate the simulation process. Simulation results showed excellent agreement with benchmark measurements with an Fe-55 source and a Si(Li) detector. Use of this code in conjunction with a Monte Carlo code that simulates true spectral responses will allow one to simulate the actual pulse height spectra obtained for radiation analyzer systems. This, in turn, will allow the use of a suitable nonlinear approach for the routine analysis of in vivo medical or on-line process samples at very high counting rates.

The Lahey/Fujitsu Fortran 95 Compiler Release 5.50a on Windows XP was used to create the included executable. The executable can also be run under Windows 2000, but the code cannot be run on other computers because the Fortran source is not included. The package is transmitted on a CD in a WinZIP file that contains the user's guide, the Windows executable and test cases. Reference: User's Guide (February 2004). Fortran 77; PC Windows (P00528PC58600).

OP SYS: Unix, Windows
Language: N/A
Computers: Workstation, PC
Format: Unix, tar

Oak Ridge National Laboratory, Oak Ridge, Tennessee, contributed this multi-temperature, neutron cross section library based on ENDF/B-V and ENDF/B-VI for use with MCNP. Point-wise cross sections that exist in most MCNP neutron libraries contain data for room temperature, i.e., at 294K. Although some isotopes contain data generated at one or more temperatures other than the room temperature. The availability of data for a wider range of temperatures is important for applications such as criticality safety. For this purpose, point-wise cross sections in ACE format were generated for 134 nuclides at 7 temperatures, including 0K, 294K, 373.15K, 423.15K, 473.15K, 523.15K, 587K.

The cross sections in the new library are called YUMMY (YUcca Mountain MCNP-librarY) were generated with the NJOY99.90 code. In NJOY, a 0.1% tolerance was utilized in the RECONR, BROADR and THERMR modules. For data generation at 0K, only the RECONR and ACER modules were used. YUMMY contains 134 nuclides as listed in Table 1 of the package abstract on the RSICC website. This table lists nuclide identifiers in the MCNP library and their sources of data. In the new library, ENDF/B-V based data have nuclide identifier extensions of 80c, 81c, 82c, 83c, 84c, 85c and 86c for 0K, 294K, 373.15K, 423.15K, 473.15K, 523.15K, 587K, respectively. For ENDF/B-VI, extensions 91c, 92c, 93c, 94c, 95c and 96c are used. For example, 92238.80c corresponds to 238U cross sections based on ENDF/B-V at 0K.

No source files are included in this package. The code MAKXSF, which is distributed with MCNP, can be used to perform conversion between formatted, sequential access (ASCII) files and unformatted, direct access (binary) files. Two forms of the library are included in the package: ASCII and big endian binary. The YUMMY data and XSDIR files are transmitted in GNU compressed Unix tar files on 2 CDs or 1 DVD. Reference: Draft report ORNL/TM-2204/124 (June 2004). ASCII and binary; Unix workstations or PC (D00221MNYCP00).

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.

The 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.
