The energy analysis of burner reactor power systems

摘要: Currently most commercial nuclear power stations are based on thermal reactor designs called burner reactors which are. net consumers of fissile material. These form one part a larger system that generates electricity from uraniura. However, in addition to producing energy, such systems also consume the various fuels, during construction and operation. This thesis describes use energy analysis determine total required by these systems. A number factors shown influence consumption and, particular, effect extracting uranium different sources is studied detail. For ores, an important inverse relationship between ore grade investigated quantified. The physical limit at input equal its output correspond average 15 parts per million "triuranium octoxide".
