May 1998

Vigorous writing is concise. A sentence should contain no unnecessary words, a paragraph no unnecessary sentences, for the same reason that a drawing should have no unnecessary lines and a machine no unnecessary parts. This requires not that the writer make all his sentences short, or that he avoid all detail and treat his subjects only as outline, but that every word tell.--William Strunk Jr.

Topical '98 Review

The 1998 ANS Radiation Protection and Shielding Division Topical Conference, held in Nashville, Tennessee, on April 19-23, was a rousing success with over 170 attendees from 16 different countries. The meeting got off to an excellent start with provocative and stimulating presentations by Theodore Rockwell and Alan Waltar. Rockwell addressed the issues associated with the debate on low level radiation and presented the attendees with some tough challenges and responsibilities for our technical community. (The text of his presentation follows.) In his usual enthusiastic style, Waltar reviewed the current and projected needs for nuclear energy and nuclear technologies for a wide range of applications. Both talks gave definitive reasons why we should be optimistic about the future for our field.

The technical program of approximately 125 presentations covered a wide range of traditional and emerging topics, including: Monte Carlo and discrete ordinates methods, reactor pressure vessel dosimetry, nuclear data, benchmark experiments, etc. The most rapidly growing area appears to be methods and analyses for nuclear medicine applications, since the number of sessions for this topic increased from one in 1996 to three at this meeting. Building on this interest, Dr. Gary Smith presented the banquet talk on the topic of current and developing technologies for nuclear medical imaging. The conference was followed by a two-day workshop, also well attended, covering the DORT and TORT discrete ordinates radiation transport codes.

In addition to the technical program, there was a lot of fun and good food. A highlight was the dinner cruise on the General Jackson river boat. All in all, the meeting reinforced the merits of the RPS&S policy of bi-annual topical meetings. The next topical conference is scheduled for September 2000, in Spokane, Washington.

The conference proceedings are available for $50/2-volume-set plus $10 shipping & handling. Contact Bryan Broadhead by phone at 423-576-4476 or by email at broadheadbl@ornl.gov promptly since the supply is limited.

Why Low-Level Radiation Can't Cause Cancer

CHANGES TO THE COMPUTER CODE COLLECTION

Two changes or additions were made to the computer code collection during the month. One new code system was packaged and added to the collection, and one code system was replaced with a newly frozen version.

Oak Ridge National Laboratory contributed a newly frozen version of this code system for simulating atomic collisions in crystalline targets using the binary collision approximation. The new release is designated Marlowe 14c and includes several corrections and enhancements. The algorithm for locating the next collision point in a trajectory was modified to correct an error which could occur when the first proposed site was vacant. A change was made to EVENT to correct an error which occurred when atoms experiencing non-local inelastic energy losses were followed to very low kinetic energies. Two key words were redefined and another was added to the MPP glossary. More information on these and other changes is included in Section 1.11 in the Marlowe User's Guide.

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). This new MARLOWE14c also runs on Linux on an Intel PC. A limited version of the code runs on PCs under Windows using the Lahey Fortran 90 compiler. Source, scripts, test problems, and documentation files are included. No executables are included in this package, which is transmitted either on one DS/HD 3.5-in. (1.44MB) diskette in self-extracting compressed DOS files or on one diskette in a compressed tar file. References: Unpublished report (Sept. 1997), Phys. Rev. B 40, (1989), Nucl. Instrum. Methods in Phys. Res. B 48 (1990), and Nucl. Instrum. Methods in Phys. Res. B 67 (1992). Fortran 77 and C or Assembler; many computers (P00137/MNYCP/04).

Los Alamos National Laboratory, Los Alamos, New Mexico, contributed a new version of the NJOY Nuclear Data Processing System, a modular computer code for converting evaluated nuclear data in the ENDF format into libraries useful for application calculations. Because the Evaluated Nuclear Data File (ENDF) format is used worldwide (e.g., ENDF/B-VI in the US, JEF-2.2 in Europe, JENDL-3.2 in Japan, BROND-2.2 in Russia), NJOY gives its users access to a wide variety of up-to-date nuclear data. NJOY provides comprehensive capabilities for processing evaluated data, and it can serve applications ranging from continuous-energy Monte Carlo (MCNP), through deterministic transport codes (DANT, ANISN, DORT), to reactor lattice codes (WIMS, EPRI). NJOY handles a wide variety of nuclear effects, including resonances, Doppler broadening, heating (KERMA), radiation damage, thermal scattering (even cold moderators), gas production, neutrons and charged particles, photoatomic interactions, self shielding, probability tables, photon production, and high-energy interactions (to 150 MeV). Output can include printed listings, special library files for applications, and postscript graphics (plus color).

NJOY97 is a cleaned up version of NJOY 94.105 that features compatibility with a wider variety of compilers and machines, explicit double precisioning for 32-bit systems, a larger test-problem suite, a new revision control system, and some changes to the user input. This version was tested on a Cray YMP with both static and stack-based memory allocation with a Fortran-90 compiler, on a Sun Ultra in 32-bit mode using f90, on a Sun Ultra in 64-bit mode (-dbl) using f77, on a Pentium 90 using Linux g77 (32 bits with stack-based memory allocation), on an IBM RS/6000 using f77 (with f90 libraries available), and on Windows NT and Windows 95 using the Lahey LF90 Version 4 compiler. LF90 was used to create the PC executable included in the package. The Linux installation was run on Intel PC under RedHat Linux 5.0 with the EGCS package replacing the standard gcc compiler package. The package is transmitted on CD-ROM in Unix and DOS formats. References: LA-12740-M (Oct. 1994) and LA-12639-MS (1994). Fortran 77; Cray (UNICOS), SUN/UNIX; IBM/AIX.

CINDER'90 Release and Users' Class

CINDER'90 is a radionuclide inventory program developed primarily for accelerator-driven radiation environments. The code uses medium- energy reaction-product production probabilities and lower-energy particle fluxes from transport codes (HETC, LCS, MCNPX) with a library of transmutation data to calculate temporal inventories of nuclides and their decay, absorption, fission, and hazard properties.

The imminent release of CINDER'90 and its data libraries is scheduled for late July 1998. No-fee classes, limited to sixteen users each, will be offered -- June 30­July 1 and again July 14­15 -- introducing the code, libraries, and applications. Those interested in attending can contact Bill Wilson at: wbw@lanl.gov, voice 505-667-7749, fax: 505-667-9671, or W. B. Wilson, Nuclear Theory and Applications Group (T-2), Theoretical Division, Los Alamos National Laboratory, PO Box 1663, MS:B243, Los Alamos, NM 87545. A release package is now being accumulated for the class and for RSICC distribution.

(SARE-4/SATIF-4) Call for Papers

September 13-15, 1998, the Hyatt Regency in Knoxville, Tennessee, is the time and venue for the 4th Workshop on Simulating Accelerator Radiation Environments (SARE-4). As is customary, the specialist's meeting, Shielding Aspects of Accelerators, Targets and Irradiation Facilities (SATIF-4), will be held following SARE-4 on September 17-18, 1998. Dr. Tony Gabriel from Oak Ridge National Laboratory is serving as the general chair for both meetings. Co-sponsors include Oak Ridge National Laboratory, the Radiation Safety Information Computational Center (RSICC), and the OECD/NEA.

Immediately following SARE-4/SATIF-4, the American Nuclear Society will hold a topical meeting, Accelerator Applications 1998 (AccApp'98) (see following announcement), organized by the ANS Accelerator Application Technical Working Group. This meeting will be held in Gatlinburg, Tennessee, from Sept. 20-23, 1998. The current development of the Spallation Neutron Source (SNS) at Oak Ridge makes Tennessee an ideal location for this series of meetings. SARE now has three highly successful workshops to its credit.

Proceedings from previous workshops are routinely used by the community involved in physics development and applications of radiation transport codes for accelerators. With the advent of new, high-powered spallation sources, high-intensity beams for hadron and muon colliders and other facilities, the need for validated simulation codes is critical. In the US, we will soon come under close scrutiny by agencies such as the Nuclear Regulatory Commission, whose standards of proof are much higher than anything most of us have ever encountered. It is vital that long-standing issues in accelerator radiation transport be solved quickly, to the highest degree of accuracy possible. As with the previous workshops, SARE-4 will cover most aspects of the simulation of accelerator-generated radiation fields in hadron and electron machines. Specific uses of our tools include, but are not limited to:

The SARE workshops support these activities through detailed discussions of the latest developments in radiation transport codes including Monte-Carlo, deterministic and analytic methods, as well as benchmarking and validation procedures. In addition to physics and code discussions, new results on applications of radiation transport codes and methods to accelerator facilities is highly encouraged. If you are confused as to where to submit your paper, SARE-4 or SATIF-4, keep in mind that presentations at SATIF are generally followups to specific assigned topics from the previous specialist's meeting. SARE is a conference format, for the presentation and discussion of new results. We look forward to your participation in SARE-4, and please pass this announcement along to others who might be interested. If you plan to attend SARE-4, please provide the information below and return it to Bernadette Kirk at blk@ornl.gov. Look for further information on our Web site: http://www-rsicc.ornl.gov/sare/sare. html.
