NESC0887 GETOUT.

1. NAME OR DESIGNATION OF PROGRAM:  GETOUT.

3. DESCRIPTION OF PROBLEM OR FUNCTION

GETOUT is a set of four FORTRAN programs and associated subroutines developed as an aid to investigate the migration of radionuclide chains from an underground source. The model to be analyzed is an underground nuclear waste disposal site and a uniform one-dimendional soil column that connects the site with a surface water body. At an arbritrary time after the waste is deposited, the radioactive material is released to an underground aquifer which flows at constant velocity directly  through the soil column into the surface body. The program takes into account the compilations introduced by the radioactive decay of first-order chains to produce other species which have different absorption characteristics and, in turn, decay at different rates.

4. METHOD OF SOLUTION

GETOUT's programs ONE, TWO, and THREE solve analytical expressions describing the migration of single nuclides,  and 2- and 3-member chains, respectively. Program FOUR solves more complex chains described by empirical combinations of simpler chains. The equations used were developed by Lester, Burkholder, Jansen, and Cloninger. Solutions are computed for impulse release without dispersion,impulse release with dispersion, band release without dispersion, and band release with dispersion. Time/inventory profiles are calculated.

5. RESTRICTIONS ON THE COMPLEXITY OF THE PROBLEM

Maxima of -
    88 discharge profiles
    51 single chains
    26 two-member chains
    11 three-member chains

6. TYPICAL RUNNING TIME

NESC executed the four programs in 320, 225,  280, and 150 CP seconds, respectively, on an UNIVAC 1100/44.

7. UNUSUAL FEATURES OF THE PROGRAM

GETOUT can be executed in either batch or interactive mode.

8. RELATED AND AUXILIARY PROGRAMS

Data for the inventory library, MINV, are typically derived from the output of a program such as ORIGEN (NESC Abstract 874).

11. MACHINE REQUIREMENTS

Program ONE requires 29,000 words of main memory and 205,000 words of direct access storage for execution.
Programs TWO and THREE require 31,000 words of main memory and 86,000 and 47,000 words of direct access storage, respectively, and  program FOUR requires 44,000 words of main memory and an additional  475,000 words of direct access storage for execution.

13. OPERATING SYSTEM UNDER WHICH PROGRAM IS EXECUTED:  EXEC 8.

14. OTHER PROGRAMMING OR OPERATING INFORMATION OR RESTRICTIONS

Programs ONE, TWO, THREE, and FOUR must be executed in sequence. The intermediate output for each of the 1-, 2-, and 3-member chains is written to separate files on a disk. These files may be examined and, if desired, edited before program FOUR is executed. Each pro- gram makes use of the UNIVAC system routine FACSF for interpretation and processing of an Executive control statement within the program.  These programs should be compiled under the ASCII (FTN) compiler. Modifications are necessary to compile the programs under the older  FORTRAN V E3 and T3 compilers.
