RSICC CODE PACKAGE CCC-623
1. RISKIND 2.0: A Computer Program for Calculating Radiological Consequences and Health Risks from Transportation of Spent Nuclear Fuel.
2. CONTRIBUTOR
Argonne National Laboratory, Environmental Assessment Division, Argonne, Illinois.
3. CODING LANGUAGE AND COMPUTER
Fortran 95 (35%), Microsoft Visual Basic (60%), C (5%); Pentium (C00623IBMPC02).
4. NATURE OF PROBLEM SOLVED
RISKIND 2.0 was developed for the analysis of radiological consequence and health risks to individuals and the collective population from exposures associated with the transportation by either truck or rail of spent nuclear fuel or other radioactive materials. The software is intended to provide scenario-specific analysis when evaluating alternatives for environmental assessment activities, including those for major federal actions involving radioactive material transport as required by the National Environmental Policy Act (NEPA).
RISKIND 2.0 is an upgrade from the previous release of RISKIND (ver. 1.11). The primary difference between the two versions is the addition of a geographic information system (GIS) component, the SylvanMaps(R) OCX map control (http://www.sylvanmaps.com). Other upgrades include improved file input/output and use of the Windows® Help file system.
5. METHOD OF SOLUTION
RISKIND 2.0 offers a user-friendly WindowsTM point-and-click interface for problem entry. Standard health physics models are used for determining routine radiological exposure to external radiation sources. The accident scenario portion of the program incorporates a Gaussian puff air dispersion model for atmospheric releases. The air dispersion model includes a virtual point source model, wet/dry deposition, plume depletion, and can account for initial thermal buoyancy effects.
For accident scenarios, a geographical information system module is available to map the accident location and provide population data to the exposure calculations. Non-transportation related releases of radioactive material, accident or terrorist initiated events may also be modeled. A spent nuclear fuel database developed for DOE is included for determining the radioactive material present in a typical spent nuclear fuel cask. The program incorporates the Nuclear Regulatory Commission's "Modal Study" (NUREG/CR-4829) severity categories and associated release fractions of material. With appropriate initiating event input, RISKIND can determine the appropriate release category to be used for an analysis.
6. RESTRICTIONS OR LIMITATIONS
If the new GIS features are to be used, the recommended computer platform is a 400 MHz or faster PC with 128 MB or more of memory to handle the increased demands imposed by the map display. However, memory related problems have been seen on 128 MB machines, especially when other applications are running at the same time. The SylvanMaps OCX map control is used. SylvanMaps runtime libraries are distributed royalty free with RISKIND 2.0 as are Microsoft Access libraries (the map control stores the GIS data in Access databases). RISKIND also has the capability to import a number of industry standard GIS data formats using an import utility associated with the SylvanMaps OCX map component. Therefore, map generation within RISKIND is a straightforward process if site data are readily available in one of these formats. These formats are listed below.
- *.SHP (ArcView Shape File Format)
- *.MIF (MapInfo Interchange Format)
- *.DLG (USGS Digital Line Graph)
- *.DWG (AutoCAD R12 Drawing File)
- *.DXF (AutoCAD Exchange Format)
See the Troubleshooting section of Readme.txt.
7. TYPICAL RUNNING TIME
In general, running time is from one second to greater than 10 minutes. Four sample input files were test at RSICC, the sample_1 & 2 running time is less than one second each, and GIS sample_1 & 2 running time is about 4 minutes each on an Pentium 1GHz machine running Windows XP Professional.
8. COMPUTER HARDWARE REQUIREMENTS
The recommended computer platform is a 400 MHz or faster PC with 128 Mbytes or more of memory to handle the increased demands imposed by the map display. RISKIND 2.0 requires approximately 120 Mbytes of hard disk space for installation of all options.
9. COMPUTER SOFTWARE REQUIREMENTS
RISKIND will run on machines under Windows 95/98/ME/NT/2000/XP operating systems. The executables included in the package were created with Lahey Fortran 95 V5.5 and MS Developer Studio 6 (Visual Basic 6 and Visual C 6). Source files are not included.
