1. NAME AND TITLE
RABFIN, PARTS: Code System for Calculating Gaseous Effluent Dose Parameters.
Nuclear Regulatory Commission, Washington D. C. through the Energy Science and Technology Software Center, Oak Ridge, Tennessee.
3. CODING LANGUAGE AND COMPUTER
FORTRAN IV; IBM PC (C00668/IBMPC/00).
4. NATURE OF PROBLEM SOLVED
RABFIN calculates technical specification dose parameters for the noble gas portion of gaseous effluents from nuclear power plants. Finite noble gas doses from short-term (purge) releases are calculated; the output includes the finite plume air, total body, and skin doses. Corresponding dose quantities computed assuming semi-infinite exposure geometry are also presented for comparison purposes. PARTS calculates technical specification dose parameters for the iodine and particulate portions of gaseous effluents.
5. METHOD OF SOLUTION
RABFIN employs the atmospheric dispersion models of the XOQDOQ (CCC-316) program and the dose integral routine of the U. S. Nuclear Regulatory Commission Regulatory Guide 1.109.
6. RESTRICTIONS OR LIMITATIONS
Maxima of 50 nuclides (PARTS), 20 nuclides (RABFIN), 14 wind speed classes (RABFIN), and 7 stability classes (RABFIN). No provision is included to evaluate simultaneously multiple releases, e.g., a continuous and purge release.
7. TYPICAL RUNNING TIME
NEADB executed the sample problems in 7 and 3 seconds, respectively, on a DELL Optiflex 560/L PC.
8. COMPUTER HARDWARE REQUIREMENTS
PC 486 or faster is recommended with 640 kb RAM and 1 Mb free disk space.
9. COMPUTER SOFTWARE REQUIREMENTS
For the PC version, DOS 6 or higher is recommended. Lahey F77-EM/32 V5.2 compiled executables are included in the package. These can be run in a DOS window of Windows95.
