radioactivity heat
1.Using an activation calculation code FDKR and decay chain data library AF-DCDLIB to calculate the radioactivity, decay heat, dose rate and biological hazard potential (BHP) from activation products, actinides and fission products, in a Fusion Experiment Breeder (FEB).
2.The calculation results show that the total radioactivity inventory, decay heat and BHP are 2.1010~(16) Bq, 5.0610~(-3)MW, 68.6km~3(kW)~(-1), respectively, at shutdown after one year operation with 500 MW fusion power.
3.The code and library are introduced briefly, and calculation results are given and decay curves of related hazards after one yr operation with 150 MW fusion power. The total radioactivity inventory, decay heat and BHP are 5. 74X1020Bq,8. 34 MW and 4. 08X108 km3 of air, respectively, at shutdown.
