CCC-623/RISKIND 1.11
OP SYS: Windows 95, 98
Language: Fortran F77L, Visual Basic, Borland C
Computers: PC
Format: DOS

Argonne National Laboratory, Environmental Assessment Division, Argonne, Illinois, contributed a newly frozen version of this radiological risk assessment code system for spent nuclear fuel transportation. RISKIND estimates potential radiological consequences and health risks to individuals and the collective population from exposures associated with the transportation of spent nuclear fuel or other radioactive materials by truck or rail. It offers a user-friendly Windows™ point-and-click interface for problem entry. Numeric methods are used to calculate routine (incident-free) exposure to spent nuclear fuel or other radioactive material shipments. Plume dispersion models are used to determine dose consequences from accidental releases for individuals or a local population group.

RISKIND runs on personal computers under Windows 95 and Windows 98 but will fail on WindowsNT and Windows2000. The executables included in the package were created with Lahey Fortran F77L, Visual Basic, and Borland C compilers. Source files are not included. The package is transmitted on one DS/HD 3.5-inch (1.4 MB) diskette which contains executables and sample cases written in a self-extracting compressed DOS file. Reference: ANL/EAD-1 (November 1995). Lahey Fortran F77L, Visual Basic 4, Borland C4.0; IBM PC and compatibles. (C00623IBMPC01).
 

PSR-497/EMPIRE-II Version 2.13
OP SYS: Linux
Language: Fortran 77; C
Computers: PC
Format: tar

The IAEA, Vienna, Austria, through the OECD NEA Data Bank, Issy-les-Moulineaux, France, contributed a new statistical mode system for calculating nuclear reactions in the frame of combined optical, multistep direct (TUL), multistep compound (NVWY) and statistical (Hauser-Feshbach) models. Incident particle can be a nucleon or any nucleus (heavy ion). Isomer ratios, residue production cross sections and emission spectra for neutrons, protons, alpha-particles, gamma-rays, and one type of light ion can be calculated. The energy range starts just above the resonance region for neutron induced reactions and extends up to several hundreds of MeV for the heavy ion induced reactions.

This current release of EMPIRE runs under Linux Red Hat 6.1 using g77 compiler. The full functionality requires: Fortran 77 or 90 compiler, C compiler (if not integrated with the Fortran compiler), gnuplot, grep, awk (or gawk), bash shell, and Tcl/Tk. Basic calculations should be possible on any operating system on which a Fortran 77 compiler is available. The referenced document, scripts, and test problems are transmitted on a CD in a GNU compressed tar file. Reference: Informal report (April 5, 2000). Fortran 77 and C; Linux PC systems (P00497/PC586/00).
 

CHANGES TO THE DATA LIBRARY COLLECTION


DLC-191/SINBAD 2000
OP SYS: Unix, Windows
Language: HTML
Computers: Many
Format: DOS

Oak Ridge National Laboratory, Oak Ridge, Tennessee, and the OECD NEA Data Bank, Issy-les-Moulineaux, France, contributed a newly frozen version of this shielding integral benchmark archive and database. A culmination of nearly 10 years of effort between several contributing authors resulted in the final stylization and formats for the 41 benchmark experiments contained in SINBAD 2000. This release includes a large set of 29 fission shielding benchmarks, ten fusion shielding benchmarks, and two intermediate-energy accelerator benchmarks. Work on follow-up versions of SINBAD will provide more benchmarks in fission, fusion, and accelerator shielding with new additions in radioactive waste and medical applications. The current version supplies example models and computational input for the user's benefit. Included are many benchmarks with their reference documents scanned into a searchable Adobe Acrobat® pdf format.The SINBAD retrieval system is an html indexed and hyperlinked table, sorted alphabetically by shield material, year of publication, laboratory, shield-type, and filename. Each of the table entries are linked to their html formatted abstract in the subdirectories of SINBAD 2000 data. The abstract is hyperlinked to the experimental html document within each of the subdirectories. Included in most benchmark subdirectories are computational data and original documents that have been scanned in Acrobat® pdf format.

The data are provided in HTML 3.1 format compatible with most UNIX, Microsoft® Windows™, and Apple® platforms. The HTML browsers that are compatible with these platforms open the data files. The size of each benchmark may range from a few hundred kilobytes to over a megabyte depending on the number of associated graphical and tabular files. The total disk space requirement is approximately 200 MB. Reference: SINBAD 2000 help files and examples. HTML; UNIX Workstations, PC, MAC (D00191ALLCP02).
 

DLC-201/PWR-AXBUPRO-SNL
OP SYS: Windows
Language: Excel
Computers: Many
Format: DOS

Yankee Atomic Electric Company, Bolton, Massachusetts, through the OECD NEA Data Bank, Issy-les-Moulineaux, France, contributed this axial burnup profile database for pressurized water reactors. The data were obtained directly from utilities whose reactors represent the range of commercial PWR fuel lattices. The work was performed by Yankee Atomic Electric for Sandia National Laboratory. All axial burnup profiles were calculated from 3-D depletion analyses of the core configuration. The organizations and utilities providing axial burnup profiles for the database used different model codes for the 3D-depletion calculations. The model codes used were: SIMULATE-3, NEMO, ANC, and PRESTO-II. Cross-section inputs describing the assemblies are derived from assembly lattice calculations. SIMULATE and NEMO used CASMO-3 to generate cross sections, ANC used PHOENIX, and PRESTO-II used RECORD. The nodal calculations were performed typically in a quarter core symmetric configuration using 12 to 25 nodes to describe the axial direction and one to four nodes to describe the radial direction of each assembly. The data cover a range of burnup from slightly over 3 GWd/MTU to 55.3 GWd/MTU and an enrichment range of 1.24 w/o to 4.75 w/o U-235. Fuel designs contain different poison absorbers such as borosilicate glass, B4C, Integral Fuel Burnable Absorber (IFBA), erbium and gadolinium. The database consists of 3169 computed axial burnup profiles, covering 106 cycles of operation.

The data may be opened with Microsoft Excel-97. They are transmitted on a CD which includes the database and report written in a self-extracting compressed DOS file. Reference: YAEC-1937 (May 1997). ASCII/Excel (D00201MNYCP00).
 

DLC-206/HATCHES 12.R2
OP SYS: windows
Language: Access
Computers: PC
Format: DOS

Harwell Laboratory, Oxfordshire, United Kingdom, through the OECD NEA Data Bank, Issy-les-Moulineaux, France, contributed this collection of data for use in radiochemical modeling work. The data base includes thermodynamic data (the log formation constant and the enthalpy of formation for the chemical species) for the actinides U, Th, Pu, Np, Am and Cm and for fission products including Cs, Ru, Tc and Sr. HATCHES was created using the Microsoft® Access Software on a MS Windows computer, and does not require the proprietary Access software. Output options are provided to convert the contents of the database into the format required by the PICKER/PHREEQE programs or to create the components of a data file for use with the EQ3/6 program.

At present the database has only been compiled for use at 25 degrees C. In a limited number of cases, the enthalpy data required for calculations at other temperatures are included; but these data were not used at Harwell. Statistical error analyses of the measurements are included. The package is transmitted on a CD written in DOS format. Reference: User Manual (March 1999). Microsoft® Access executable, Personal Computer (D00206PC48600).
