A method to enable the fast and perfect transmutation of minor actinides(MA) using an ultra high flux reactor is proposed. For this purpose, the conceptual design of A-Burner was considered based on the ANS reactor being developed at ORNL. The concept of two stage transmutation, where MA from the PWR is irradiated in the well thermalized reflector region then higher actinides from Cm are burned at the core center, is adopted. It is found that 28kg of MA are incinerated in one year in the reflector, 2.2kg of higher MA from Cm decreases to 0.5kg in one year and becomes 0.5g after 5 year irradiation.
