1. NAME AND TITLE
GIRAFFE: General Isotope Release Analysis For Failed Elements
Argonne National Laboratory, Argonne, Illinois.
3. CODING LANGUAGE AND COMPUTER
Fortran IV; IBM 3033.
4. NATURE OF PROBLEM SOLVED
GIRAFFE was designed to provide parameter estimates of the nonlinear discrete measurement models that govern the transport and decay of delayed neutron precursors in a liquid metal fast breeder reactor(LMFBR).
5. METHOD OF SOLUTION
GIRAFFE incorporates the physical model for isotopic transport and decay into a systematic regression algorithm that enables the user to determine the values of the transport and release parameters. The code also computes the values of several descriptive statistics that provide additional diagnostic information for interpreting the delayed neutron signals and characterizing the condition of breach.
6. RESTRICTIONS OR LIMITATIONS
7. TYPICAL RUNNING TIME
The sample problem took only a few seconds on the Data General MV 4000 under the AOS/VS operating system.
8. COMPUTER HARDWARE REQUIREMENTS
The code was originally developed for the IBM 3033 computer. It can also run on the Data General MV family.
9. COMPUTER SOFTWARE REQUIREMENTS
The code was written in Fortran IV under the IBM VM/CMS operating system.
