Activation Calculation for a Fusion Experimental Breeder, Feb-E

Using an activation calculation code FDKR and its associated data library AF-DCDLIB to calculate the radioactivity, decay heat, waste disposal rating and biological hazard potential from activation products, actinides and fission products in the FEB-E. The codes and libraries used in calculation are introduced briefly, and calculation results and decay curves of related hazards after the shutdown of one-year operation of the FEB-E are given. Results obtained show that the total radioactivity inventory, decay heat and BHP at shutdown are 5.74 × 10¹³MBq, 8.34MW and 4.08 × 10⁸km³ of air for 316SS structure material, respectively.
