Assessment of the occupational dose rate during fuel handling and storage of various fuel cycles used in the super-critical water reactor and the impact on deep geological repository performance

The Canadian concept of the Pressure-Tube Super-Critical Water-Reactor (PT-SCWR) uses Pu/Th in a once-through fuel cycle. The implication of using Pu/Th in a PT-SCWR on the safety of the workers in the Deep Geological Repository (DGR) facilities as well as on the public after the closure of the DGR was investigated. A comparison between the Pu/Th and other fuel cycles, namely, U/Th (two U/Th fuels with different enrichments and different …
