摘要: Burnup characteristics of rock-like oxide (PuO2-ZrO2: ROX) fueled LWR have been studied with an additive ThO2, UO2 or Er2O3. A ROX core has reactivity coefficients and burnup swing problems, which can be mitigated by these additives. From the calculations LWR, it was found that ThO2 causes a few percent decrease in Pu transmutation fuel, while Er2O3 decreases largely. The production 241 Am, is parent long-lived 237Np, smaller added fuel than fuel. However, productions 243Am 244Cm are more those fission products (LLFPs) nearly same as Er2 O3 As result minor actinides (MAs) LLFPs productions, ingestion radiotoxicity hazard index spent is...
