Burnup computations of online-refueling process for pebble-bed reactors using layer-mixed-shell fuel movement model

This study aims to propose a model for dynamically simulating the online-refueling process in pebble-bed reactor (PBR) using MCNPX. PBR has a special feature of online-refueling which can greatly reduce the outage time and enable a higher burnup in spent fuel. However, this feature also results in t...
