Molten Chloride Fast Reactor (MCFR) emerges as the potential technology for use as a nuclear marine propulsion system, but the initial fuel cost can be expensive. To reduce the initial cost, the MCFR can use reactor grade plutonium (RGPu) and even higher order plutonium (HOPu). Burnup calculation using Serpent-2 and ENDF/B-VII.0 code shows that fissile Pu content from RGPu can be reduced from 67.7% to 27.3% in 32 years. Therefore, Pu-fuelled MCFR offers a strong case for its use in nuclear marine propulsion system to destroy waste and minimising initial fuel cost.
