Gaerttner LINAC Receives ANS Landmark Award

From the June 1998 Nuclear News--"For over 35 years of generating accurate data for nuclear reactor designs, the Gaerttner LINAC Laboratory at Rensselaer Polytechnic Institute was awarded a Nuclear Historic Landmark Award by ANS. The high-power electron linear accelerator has served government as well as industry applications since the early 1960s, and was one of the first to provide intense pulsed beams of neutrons for time-of-flight experiments."

Robert Block, current director of the laboratory, accepted the award from Ted Quinn, ANS president-elect and RPI alumnus, in an April 3 ceremony hosted by the ANS Eastern New York Section and RPI.

During its many years of operation, the Gaerttner LINAC Laboratory conducted measurements of neutron thermalization, neutron cross-sections on both stable and radioactive isotopes, neutron spectra from large pulsed assemblies, photoneutron production, radiation effects in components, and the effects of intense radiation in microelectronics. The plutonium-239 alpha measurements carried out jointly with the Oak Ridge National Laboratory showed that the steam-cooled intermediate spectrum breeder concept would not be practical because of the high alpha measured in this energy range. "As a result, the breeder program shifted its focus exclusively to the liquid-sodium-cooled LMFBR design. Numerous measurements were carried out in support of the LMFBR, as well as for thermal reactors, and today there is a strong program in low-energy cross-section measurements."

We in the Radiation Safety Information Computational Center have enjoyed a long reciprocal relationship with the staff and students of RPI. We congratulate those who have and are operating the Gaerttner LINAC Laboratory on receiving this award. If you wish to learn more about the Gaerttner LINAC Laboratory you will find additional information at http://www.linac.rpi.edu/


Four changes or additions were made to the computer code collection during the month. Three new code systems were packaged and added to the collection, and one code system was corrected. Two changes resulted from foreign contributions.

Oak Ridge National Laboratory contributed a replacement for the MORSE portion of this Monte Carlo code system for the design and analysis of calorimeter systems, Spallation Neutron Source (SNS) target systems, etc. CALOR95 was designed to assist experimentalists evaluate and analyze different types of calorimeter systems used in many high-energy physics experiments to determine the energy and direction of incident hadrons, leptons, and photons. The code package contains HETC95, SPECT95, EGS4, MORSE, and other support programs. The MORSE version in earlier releases of CALOR95 did not yield the correct energy balance because absorbed gamma-ray energies were underestimated.

CALOR95 runs on IBM RS/6000 computers and requires the XLF Fortran 77 compiler. It is transmitted on either one CD-ROM, DC 6150 (150 MB), 4-mm DAT (8GB), or 8-mm (2.3GB) cartridge tape in compressed UNIX tar format. References ORNL/TM-11185 (unpublished report) and SDC-92-00257 (May 1992). Fortran 77; IBM RS/6000 (C00610/IRISC/01).

The Faculty of Physics and Nuclear Techniques, University of Mining and Metallurgy, Cracow, Poland, contributed a new code system for one-dimensional transport and burnup calculations. In BISON-C the one-dimensional transport equation is solved by the discrete ordinates method with anisotropic scatterings. Bateman's method is adopted to solve the production-depletion equations for burnable nuclides. A burnup calculation is carried out by performing these two processes iteratively.

The BISON-C system was based on CCC-464/BISON 1.5, which was based on CCC-254/ANISN-ORNL. The new code system extends the original code by providing burnup calculation for fission products and other features like differentiation of time steps and burnup normalization to the required thermal power. The new burnup library, based on JENDL-3, additionally contains the fission product burnup chain and the fission yields for actinides prepared from ENDF-B/VI data files. Included is a cross-section library processing system which is comprised of XSCON, RESPL, and SIGC. BISON-C runs on Unix-based operating systems on IBM RS/6000 and HP and requires a Fortran 77 compiler. It is transmitted on 2 DS/HD diskettes in a compressed Unix tar file. Reference: INT 271/I (1997). Fortran 77; IBM RS/6000 and HP (C00659/MNYWS/00).

Argonne National Laboratory-West, Idaho Falls, Idaho, contributed this computer code system for generalized least-squares evaluation of related cross sections for ENDF/B based on Gauss, Markov, and Aitken. The simultaneous evaluation of the interrelated cross section data of 6Li(n,), 6Li(n,n), 10B(n,0), 10B(n,1), 10B(n,n), 197Au(n,), 238U(n,), 235U(n,f), 239Pu(n,f), 238U(n,f) and the thermal constants was part of the evaluation of these data for ENDF/B-VI. The Fortran codes and the data files used for the simultaneous evaluation are included in this package. This experimental data analysis code system, known as GMA, utilizes the generalized least-squares estimation method. Associated codes included are RCL (which is used to edit, list and expand the basic data file) and DAT (which is used to reduce the cross section data to a common energy grid.)

GMA runs on UNIX operating systems on Sun and IBM RS/6000 workstations and on personal computers. Executables created with the LAHEY F77L3/EM-32 5.2 compiler are included to run on PCs in a DOS window of Windows95. The package is transmitted on 2 DS/HD diskettes in both UNIX and DOS compressed formats. References: ANL/NDM-139, (ENDF-358)(1997). Fortran 77, Fortran 90; Pentium-based PC, and Sun and IBM RS/6000 workstations (P00367/MNYCP/00).

The Department of Nuclear Reactions at Moscow State University, Russia, contributed this code system designed for quick and easy estimations of basic stopping characteristics of proton transmission for generation of the source definition (SDEF) portion of the input data for MCNP. It does not generate the full MCNP input file. The MSM-SOURCE code generates the input data for the MCNP code (for 3b and 4 versions), simulating the set of single neutron sources, produced in the sample during the proton transmission. It permits one to extend the possibilities of the MCNP code for consideration of secondary neutrons from the proton interaction with nuclei of the sample substance. The MSM-SOURCE code is applicable for calculations of the proton transport for the incident energies from 0.1 to 1 GeV and various targets 12 < A < 238.

This code is based of the Moving Source Model (MSM) and Bethe stopping theory with the relativistic corrections for protons. It allows the estimations of the proton range, the changes of the proton current and the neutron production versus the depth. The double differential spectra and the multiplicities of nucleons, produced in the primary proton-induced reactions, are obtained.

MSM-SOURCE runs on many computers including personal computers and IBM RS/6000 under either DOS or UNIX. It has been compiled with Microsoft Fortran 5.1, WatCom Fortran, NDP-Fortran, and Lahey compilers on PC. The Lahey Fortran 90 V4.5 compiler was used to create the executable included in the package which is transmitted on one DS/HD (1.44MB) diskette written in DOS format.
