1. NAME AND TITLE
FDKR: Radioactivity and Dose Rate Calculation Code for Fission, Fusion and Hybrid
AF-DCDLIB: Decay Chain Library for Activation Products, Fission Products and Actinides.
FDKR is based on CCC-323/DKR, which originated at the University of Wisconsin in 1976.
Southwestern Institute of Physics, Leshan, Sichuan, People's Republic of China.
3. CODING LANGUAGE AND COMPUTER
Fortran 77; IBM 4381.
4. NATURE OF PROBLEM SOLVED
The main purpose of FDKR is to calculate the radioactivity-related parameters of fusion-fission
hybrid reactors. Once neutron flux is provided, FDKR can also be used for pure fusion or fission
5. METHOD OF SOLUTION
The construction of linear decay chains and the solution of activation product chains are those
adopted in the CCC-323/DKR code, on which FDKR is based. The generation and loss rates of fission
products are added to the relevant chains. All necessary data are provided, resulting in a much larger
data library AF-DCDLIB than DCDLIB used in DKR. AF-DCDLIB was specially designed for
FDKR. The data are mainly generated from ENDF/B-IV and contain relevant data for 508 nuclides:
42 actinides, 323 nuclides of fission products and 143 activation material nuclides. The neutron cross-sections are from ENDF/B-V and were processed into a 46 energy-group structure using TCP. Fission
products with the same names, but resulting from different fission fuels are traced separately.
6. RESTRICTIONS OR LIMITATIONS
7. TYPICAL RUNNING TIME
For a typical hybrid reactor with 2 fission fuel zones and 25 intervals, the run time of radioactivity-related calculation on the IBM 4381 is about 400 seconds.
8. COMPUTER HARDWARE REQUIREMENTS
The code runs on an IBM 4381 and requires approximately 8 megabytes of virtual memory and
4 megabytes of core storage.
9. COMPUTER SOFTWARE REQUIREMENTS
FDKR runs under the VM/SP operating system (Release 4.0) using the IBM VS Fortran compiler.
