2.         CONTRIBUTORS

U.S. Nuclear Regulatory Commission, Washington, D.C., USA.

3.         CODING LANGUAGE AND COMPUTER

Fortran IV with updates; PC, MAC (C00506MNYCP02).

 

4.         NATURE OF PROBLEM SOLVED
            GALE is a computerized mathematical model for calculating the release of radioactive material in gaseous and liquid effluents from boiling water reactors (BWRs) and pressurized water reactors (PWRs). The calculations are based on data generated from operating reactors, field tests, laboratory tests, and plant-specific design considerations incorporated to reduce the quantity of radioactive materials that may be released to the environment. The CCC-506/GALE86 code package was developed as a newer tool based on more recent information published in NUREG-017, Rev. 1. RSICC retains the CCC-335/GALE package for use with plants licensed with the earlier technology.

5.         METHOD OF SOLUTION

       GALE calculates expected releases based on 1) standardized coolant activities derived from ANS Standards 18.1 Working Group recommendations, 2) release and transport mechanisms that result in the appearance of radioactive material in liquid and gaseous waste streams, 3) plant-specific design features used to reduce the quantities of radioactive materials ultimately released to the environs, and 4) information received on the operation of nuclear power plants.

6.         RESTRICTIONS OR LIMITATIONS

The liquid release portion of GALE uses subroutines taken from the ORIGEN program (CCC-217) to calculate radionuclide buildup and decay during collection, processing, and storage of liquid radwaste. Memory requirements for this part of the program are determined by the large nuclear data base accessed by these subroutines.

 

7.          TYPICAL RUNNING TIME

      A few seconds.

8.         COMPUTER HARDWARE REQUIREMENTS

PC and MAC.

9.         COMPUTER SOFTWARE REQUIREMENTS

Linux, Windows and MacOS platforms.  A Fortran compiler is required if compiling source.
