No. 404 August 1998
True opinions can prevail only if the facts to which they refer are known; if they are not known, false ideas are just as effective as true ones, if not a little more effective.--Walter Lippmann


Three changes or additions were made to the computer code collection during the month. Two code systems were replaced with newly frozen version and an additional hardware version was added to an existing code system. One change resulted from a foreign contribution.

Oak Ridge National Laboratory, Oak Ridge, Tennessee, contributed a new hardware version of ASOP to run on IBM RS/6000 workstations. ASOP is a shield optimization calculational system based on the one-dimensional discrete ordinates transport code system ANISN (CCC-254). It has been used to design optimum shields for space applications of SNAP zirconium-hydride-uranium-fueled reactors and uranium-oxide fueled thermionic reactors and to design beam stops for the ORELA facility at ORNL. A Fortran 77 compiler is required to compile and run the code. The package is transmitted in a Unix tar file on one DS/HD diskette. Reference: CTC-INF-941 (September 1969). IBM RS/6000; Fortran 77 (C00125/IRISC/00).

The Institute of Nuclear Sciences "Vinca" Nuclear Engineering Laboratory "NET" Beograd, Yugoslavia, contributed a newly frozen version of this code system to compute photon/electron/positron radiation transport problems in three dimensions with or without the presence of macroscopic electric and magnetic fields for dosimetry, radiation damage, radiation therapy and other applications. The code was upgraded to incorporate a variety of numerical experiments. Numerous corrections were made in addition to enhancements to simplify use of the system. Physical rigor is maximized by employing the available cross sections and sampling distributions, and the most complete physical model for describing the transport and production of the photon/electron/positron cascade from 20.0 MeV down to 1.0 keV. The condensed history Monte Carlo method (Berger 1963) is used for the electron and positron transport simulation. During a history the particles lose energy in collisions, and the secondary particles are generated on the step according to the probabilities for their occurrence. Electron (positron) energy loss is through inelastic electron-electron (e-,e-) and positron-electron (e+,e-) collisions and bremsstrahlung generation.

FOTELP/EM runs on either IBM PC or VAX computers. A Fortran 77 compiler is required to create executables on the VAX. The FOTELP/EM package can be installed and run on a PC with at least 8 MB of RAM under MS-DOS 6 or WINDOWS 3.1 and higher. The Microsoft Powerstation 4.0 compiler was used to build the executables which are included. The package is transmitted on one DS/HD 3.5-in. (1.44 MB) diskette in a DOS self-extracting file. Reference: NET-87 (1998). Fortran 77; PC 486 or VAX (C00581/IBMPC/01).

Argonne National Laboratory, Argonne, Illinois, contributed a newly frozen version of this optical-statistical model code system developed for the calculation of energy averaged neutron induced nuclear reaction cross sections. In the present form, ABAREX uses a version of the Racah and Clebsch-Gordon routine and a non-linear fitting routine developed at ANL. Known errors were corrected and significant improvements were made in portability. The new release runs on IBM compatible personal computers and VAX/VMS systems. The Lahey F77L-EM/32 Version 5.2 compiler was used to create the PC executable which is included in the package. Reference: ANL/NDDM-145 (June 1998). Fortran 77; PC, VAX (P00248/MNYCP/00).
