Abstract
A fundamental aspect of nuclear power is using the prepared nuclear fuel once and then dumping it as waste, most of it can be recycled, thus closing the fuel cycle. The current means of doing this is by separating and recycling the plutonium. This plutonium is then blended with natural uranium to form mixed oxide (MOX) fuel. Neutronics calculations for the Gas-Cooled Fast Reactor are performed by OpenMC - Monte Carlo neutron and photon transport code. The parameter observed is the infinite multiplication factor (kinf), where it has been concluded that increasing the plutonium percentage has an impact on increasing the value. Depletion was carried out on the MOX composition with the best results, namely 9%, 10%, and 11% based on the value kinf ≈ 1. The depletion results also gave good results as shown by the cell successfully reaching a critical condition with an effective multiplication factor ≈ 1.
