The MA incineration capability for a 500 MWth MSFR with FLiNaK salt is analyzed.
Both on-line MA feeding and 233U extraction are favorable to improving the MA incineration capability and the net 233U production.
The MA incineration amount, the depletion ratio of MA to heavy nuclei and the MA incineration efficiency can achieve 7301 kg, 77.4% and 33.8 kg/TWh within 50 years operation.
A 233U breeder mode can be achieved with a doubling time of 39 years.
