Activation Calculation for a Fusion-driven Sub-critical Experimental Breeder, FDEB

Activation Calculation for a Fusion-driven Sub-critical Experimental Breeder, FDEB

In fusion breeders, the flux and energy spectra of neutrons undergo a great change throughout the first wall and blanket. Therefore, to get correct spatial and temporal distributions of radioactive nuclides, a calculation method practical for a fission breeder cannot be directly applied in a fusion breeder. As a result, a code FDKR, which is applicable to radioactivity calculations for fusion breeders, has been developed and its corresponding decay chain library has been produced. Radioactivity, afterheat, BHP and WDR calculations have been performed for the FDEB using the code FDKR, and results are given.
