RSICC CODE PACKAGE CCC-454
1. NAME AND TITLE
DISPERS: Collection of Mathematical Models for Dispersion in Surface Water and Groundwater.
U. S. Nuclear Regulatory Commission, Washington, D. C through the Energy Science Technology Software Center, Oak Ridge, Tennessee.
3. CODING LANGUAGE AND COMPUTER
Fortran IV, BASIC II; CDC-6600, IBM PS/2 (C00454MNYCP00).
4. NATURE OF PROBLEM SOLVED
DISPERS computes the fate of routinely or accidentally released radionuclides in surface water and groundwater.
5. METHOD OF SOLUTION
The mathematical models in DISPERS are straightforward simulations of dispersion with constant coefficients and, in general, simple geometries. The SSTUBE and TUBE programs are useful for two-dimensional dispersion of a continuous source into a river after steady state has been attained. The RIVLAK program also applies to dispersion in a river, but the source may be steady or unsteady. GROUND is used for calculating the dispersion in a three-dimensional aquifer and is most useful for determining the concentration at wells downgradient of a source released from a vertical plane. GRDFLX provides the same function but it considers a horizontal area source.
8. COMPUTER HARDWARE REQUIREMENTS
DISPER is operable on the CDC-6600 computers and IBM PS/2 PC.
9. COMPUTER SOFTWARE REQUIREMENTS
Fortran IV and BASIC II compilers are required. No executables are included in the package.
