Closed Fuel Cycle and Minor Actinide Multirecycling in a Gas-Cooled Fast Reactor

Figure 8

Amounts of MA and DU added to the fuel after each cycle, in order to make 𝑘_eff,final=1.05. In the first reprocessing, purely MA is added to increase the end-of-cycle 𝑘_eff in the next irradiation campaign. In subsequent campaigns, a mix of MA and DU is used.
