CCC-0602 SMART-BNL.

1. NAME OR DESIGNATION OF PROGRAM:  SMART

3. DESCRIPTION OF PROGRAM OR FUNCTION

SMART calculates early offsite  consequences from nuclear reactor accidents. Once the air and ground concentrations of the radionuclide are estimated, the early dose to  an individual is calculated via three pathways: cloudshine, short-term groundshine, and inhalation.

4. METHOD OF SOLUTION

The model predicts time-integrated air concentration of each radionuclide at any location from release as a function of time-integrated source strength using the Gaussian profile or, optionally, as an average over the cross-section based on a top-hat distribution.
The solution procedure uses simplified meteorology and involves direct analytic integration of air concentration equations over time and position. Dispersion parameters are calculated from exponential  fits to the Pasquill-Gifford curves for six atmospheric stability classes designated A to F.

5. RESTRICTIONS ON THE COMPLEXITY OF THE PROBLEM:  None noted.

6. TYPICAL RUNNING TIME

SMART is an interactive code, and the sample  problem runs in a few seconds.

11. MACHINE REQUIREMENTS

SMART runs on IBM PC or compatible computers  under DOS and VAX mainframe computers running VMS.

NEA-DB ran the test included in this package on both a  DEC VAX-6000 minicomputer and a PC/80486 compatible desktop computer.

13. OPERATING SYSTEM UNDER WHICH PROGRAM IS EXECUTED

The code was written in FORTRAN 77 and was tested at RSIC using the Microsoft Version 4.01 compiler. The IBM PROFORT compiler was used to create the executable file included in the package.

The test cases executed on VAX under VMS and on PC under MS-DOS V.6.0.
