3. DESCRIPTION OF PROGRAM OR FUNCTION

FRACFLO computes the two- dimensional, space-time-dependent, convective dispersive transport of a single radionuclide in an unbounded single or multiple parallel fracture system with constant aperture. It calculates the one- dimensional diffusive transport into the rock matrix as well as the mass flux and cumulative mass flux at any point in the fracture. Steady-state isothermal ground-water flow and parallel streamlines are assumed in the fracture, and the rock matrix is considered to be fully saturated with immobile water. The model can treat a single or multiple finite patch source or a Gaussian distributed source subject to a step- or band-release mode.

4. METHODS

Analytical solutions for the transient advective-dispersive TRANSPORT of a single radionuclide through fractures (two-dimensional analysis) and rock (one-dimensional analysis) are based on Laplace and Fourier transformation techniques and a Gauss- Legendre integration scheme.

5. RESTRICTIONS ON THE COMPLEXITY OF THE PROBLEM

The flow field is assumed to be semi-infinite in the horizontal direction normal to the source, and of either finite or infinite extent in the vertical  direction orthogonal to the source. The initial concentration in both the fracture and the rock is assumed to be zero.

6. TYPICAL RUNNING TIME
NESC9411/01
NEA-DB ran the 62 test cases included in this package on a VAX-6000. Execution times varied between 0 seconds and more than three days. Detailed execution time tables are included in the  information file distributed with the package.

8. RELATED OR AUXILIARY PROGRAMS

MASCOT (NESC 9522) simulates a radionuclide decay chain in a fracture of unit thickness where diffusion into the rock matrix is ignored.

13. SOFTWARE REQUIREMENTS

VMS 5.0.

NESC9411/01
The program was tested out at the NEA-DB on a VAX-6000  computer running under VMS 6.1. The source codes were compiled with  the DEC FORTRAN compiler version 6.2.

14. OTHER PROGRAMMING OR OPERATING INFORMATION OR RESTRICTIONS

The FRACGRF and FRACGRF2D postprocessors use the proprietary CA-DISSPLA 10.5 software (see http://www.gaeinc.com) to produce graphical results. FRACFLO must be compiled using the G_FLOATING compiler option, which implements extended- range floating-point arithmetic. Other non-standard FORTRAN 77 features include extended-length variable names, the END DO state- ment, and calls to system DATE and TIME routines.
