1. NAME AND TITLE
RAD 2: Fission Product Radioactivities Calculation.
General Atomic, San Diego, California.
3. CODING LANGUAGE AND COMPUTER
FORTRAN IV; IBM 7090.
4. NATURE OF PROBLEM SOLVED
RAD 2 was designed for the calculation of fission product activity distributions in a high temperature gas-cooled reactor system. It will perform a variety of bookkeeping calculations for radioactive product decay chains of any desired length.
5. METHOD OF SOLUTION
RAD 2 requires input information concerning the release of each fission product from the fuel material or, alternately, a "diffusion parameter" from which the code system will calculate these release fractions, assuming diffusive release.
6. RESTRICTIONS OR LIMITATIONS
7. TYPICAL RUNNING TIME
No effort has been made to ascertain a typical running time. The estimated running time of the packaged sample problem: less than one minute.
8. COMPUTER HARDWARE REQUIREMENTS
RAD 2 was designed for the IBM 7040/7044 and was made operable on standard 32K IBM 7090 equipment with 3 tape units required for I-O and system.
9. COMPUTER SOFTWARE REQUIREMENTS
The IBM 7090 FORTRAN IV Monitor System was used to compile and execute the sample problem.
