To accept good advice is but to increase one's own ability.---Goethe
October SCALE Workshop Wrap-up

A new version of the SCALE Training Course was offered for the first time at ORNL. (SCALE is a modular code system used by approximately 800 persons worldwide for criticality safety, shielding, and heat transfer calculations of nuclear facility and package designs.) Based on suggestions from attendees of previous SCALE courses, the basic week-long course was expanded to two four-day segments. The first segment of the course was held October 15-18, 1996, and included 25 attendees. This segment covered the criticality analysis sequences within the SCALE system. The second segment of the course was held October 21-24, 1996, and included 21 attendees. This segment covered source characterizations and shielding sequences in SCALE. Nine attendees participated in both segments of the course; four participatns were from Asia and Europe. Within the U.S., there was representation from nuclear utilities, consultants, DOE, and the NRC. Based on evaluations by the attendees, the new format was successful.

CHANGES TO THE COMPUTER CODE COLLECTION

Three changes were made to the computer code collection during the month. A new code system was packaged and added, an existing code package was replaced with a newly frozen version, and a new software version was added to an existing package.
CCC-610/CALOR95
OP SYS: UNIX
Language: Fortran 77
Computers: Sun/IBM workstation
Format: tar
Oak Ridge National Laboratory contributed a new software version of this Monte Carlo code system for design and analysis of calorimeter systems, Spallation Neutron Source (SNS) target systems, etc. The new version runs on Sun Sparc workstations under Solaris. CALOR95 was designed to assist experimentalists in evaluating and analyzing different types of calorimeter systems used in many high-energy physics experiments to determine the energy and direction of incident hadrons, leptons, and photons. This code package contains HETC95, SPECT95, EGS4, MORSE, and other support programs.

CALOR95 is available for either IBM RS/6000 or Sun workstations and requires a Fortran 77 compiler. It is transmitted on either one CD-ROM, DC 6150 (150 MB), 4-mm DAT (8 GB), or 8-mm (2.3 GB) 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 References: ORNL/TM-11185 (unpublished report) and SDC-92-00257 (May 1992).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) or Sun Sparc (C00610/SUN05/00).

PSR-137/MARLOWE 14
OP SYS: many
Language: Fortran 77, C
Computers: many
Format: DOS, tar
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. This new release is designated Version 14 and includes many enhancements and some corrections to the scripts, preprocessor, control files, and source files. All of the changes are too numerous to list here, but these are just a few. The management of the keyword dictionary was improved and support for TABULA was added. The algorithms for finding the apsis in a collision and for evaluating the 'time' integral were replaced, allowing MARLOWE potentials to have an attractive region. The new time integral formulation is more accurate and the results of the test problems are altered in several respects. A sixth interatomic potential energy function is supplied. The scale identifying the status of cascade atoms was revised and expanded to make space for additional features. An analysis of the final states of focusons and replacement sequences was added. The histogram management procedure BOXER was redesigned as a set of less interwoven procedures.

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.) MARLOWE runs on personal computers under Microsoft DOS, version 6 using the Lahey Fortran 90 compiler Version 1.10h. Source, scripts, test problems, and documentation files are included in the package. No executables are included in this package, which is transmitted either on one DS/HD 3.5-in. (1.44 MB) diskette in self-extracting compressed DOS files or on one diskette in a compressed tar file. References: Unpublished report (1996), 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/02).

PSR-363/FRANCO
OP SYS: many
Language: WATFOR77
Computers: many
Format: DOS
Penn State University contributed a new finite element fuel rod analysis code system called FRANCO, which is a quasi-static two-dimensional code that calculates the fuel temperature and material deformation as a function of heat generation rate. Both solid and annular fuel configurations are modeled. FRANCO uses finite element theory and applications for mechanical deformation and heat conduction and determines the temperature distribution from the fuel center to the coolant adjacent to the clad at a position along the fuel rod axis. It calculates the average temperature of each radial division, the nodal displacement, and strain and stress within the fuel pellet and clad. The principal stresses which represent maximum and minimum stresses within an element result from Mohr's circle relationship between normal stresses. FRANCO is capable of predicting the thermo-mechanical behavior in the radial direction of a single fuel rod for both boiling water reactors (BWR's) and pressurized water reactors (PWR's). The cross sectional plane geometry of the fuel rod is modeled using three-node constant strain triangular finite elements.

A time-dependent problem can be simulated using quasi-static analysis when time-dependent parameters are provided. FRANCO can treat a steady-state or mild transient condition as a time-independent problem, where time-dependent parameters are input as "snap shots." Consequently, the FRANCO code is able to run faster and easier compared to other industrial codes with comparable results; and hence, FRANCO is useful in analyzing the fuel element performance as a scoping tool.

FRANCO runs on IBM personal computers and mainframes. It is written in WATFOR77, and the WATCOM compiler was used to build the IBM PC executables included in the package. At RSICC the packaged executables were tested on an IBM PC 486/DX2 66 and on an IBM Pentium under MS-DOS as bundled with Windows 95. FRANCO was also tested using the Lahey LF90 compiler (Version 1.10h) under MS-DOS as bundled with Windows 95 on an IBM PC 486. The Fortran sources were also compiled using the GNU F77 compiler Version 2.7.2 under Slackware Linux 2.0 on an IBM Pentium (60 MHZ). The package is transmitted on one 1.44 DS/HD 3.5-in. diskette written in self-extracting compressed DOS files which include the FRANCO source, PC executables, test cases and documentation files.

CHANGE TO THE DATA LIBRARY COLLECTION
One existing data library was replaced with a newly frozen version.
DLC-154/ANSLV
OP SYS: many
Language: NA
Computers: all
Format: tar
Oak Ridge National Laboratory, Oak Ridge, Tennessee contributed a newly frozen version of these pseudo-problem-independent, multigroup cross section libraries, which were generated to support the Advanced Neutron Source (ANS) reactor design studies. There were many changes in this new release which includes additional nuclides, revisions of several nuclides, and the removal of some nuclides for a current total of 138 isotopes. Details of these changes are included in a new supplemental report which is distributed with RSICC's documentation. The ANS was a proposed reactor which would have been fueled with highly enriched uranium and cooled with heavy water. The libraries, designated ANSL-V (Advanced Neutron Source Cross Section Libraries based on ENDF/B-V) are data based in AMPX master format. ANSL-V data can be used for the subsequent generation of problem-dependent fine- and/or broad-group cross sections for a wide range of applications, such as core and shield analysis, activation analyses after irradiation of certain elements in the reactor environment, and safety analyses. Problem-dependent cross sections can be derived from the ANSL-V data with the AMPX modular code system (PSR-315/AMPX-77).

ANSL-V consists of the following fine and broad groups:

  1. Fine group (99 energy groups) general purpose neutron library;
  2. Broad group (39 energy groups) general purpose neutron library;
  3. Gamma-ray interaction library containing data in 44-gamma-ray energy group structure.
  4. Coupled neutron and gamma-ray library containing data in 99-neutron and 44-gamma energy group structures.
  5. Coupled neutron and gamma-ray library containing data in 39-neutron and 44-gamma energy group structures.
Neutron and secondary gamma-ray production data in the ANSL-V library were generated primarily from evaluations in the ENDF/B-V General Purpose Library. Where evaluations for specified materials were not available in the ENDF/B-V library, ANSL-V data sets were generated from either LENDL-V evaluations or other ENDF-formatted libraries. Gamma-ray interaction data sets were generated from evaluations in the ENDF/B-V Photon Interaction Library (DLC-99/HUGO).

The AIM module of PSR-315/AMPX-77, PSR-352/SCAMPI, or CCC-545/SCALE 4.3 can be used for mode conversion of the data. Some of the AMPX utility modules are included in SCAMPI, and SCALE 4.3 and may also be used with the libraries. Note that previous versions of AMPX and SCALE will not work because of the AMPX master library format changes. References: ORNL-6618/s1 (August 1995) and ORNL-6618 (September 1990). D00154/ALLCP/01.
