Analysis on Plutonium Production In Fast Breeder Reactor (FBR) Cycle Based on Transuranium Fuel Loading

摘要

Nuclear reactor can provide some fissile materials by them self as breeder from converted fertile materials during reactor operation. Plutonium production becomes one of the important aspect in relation with recycling material of transuranic materials. Plutonium recycling program as good candidate for fuel optimization program, gives an issue of nuclear proliferation resistance due to its potential to be used as fuel for explosive devices. How to maintain higher capability of fuel breeding in the reactors should be followed by reducing the risk of nuclear proliferation such as plutonium material. As one of the important aspects from intrinsic nuclear proliferation resistance view point, level of material barrier as one of the control material which is related to higher technical difficulties (barrier) based on more complex design of nuclear explosive and fuel handling. Minor actinides (MA) as one of the recycled spent nuclear fuel, have been used and developed to be recycled for some purposes such as converted fuel for extending longer reactor operation, burning and transmutation of MA, fuel breeding of FBR as well as for proliferation resistance purposes [1-10]. In this present study, plutonium production based on transuranium fuel loading in fast breeder reactor (FBR) has been evaluated. Plutonium production can be evaluated based on fuel production as sustainable aspect as well as plutonium proliferation aspect of the reactors.
