Thats 120Amps ripple.
Two questions come to mind:
Do we really need 600Amps? What is the input and output current and duty cycles?
Could this be reduced by increasing the switching frequency to 15-20KHz? (will their core support?) This is desirable to reduce the output ripple and most IGBT's are fine with it. It also means the inductor ripple goes way down.
