This paper investigates the material attractiveness for an innovative fuel design (IFD) based on Lightbridge’s metallic fuel (MF) design. The used MF will have a plutonium vector that offers lower material attractiveness than traditional used urani

The natural background radiation consists of three main components; cosmic, terrestrial, and skyshine. Although there are currently methods available to measure the total dose rate from background radiation, no established methods exist that allow fo
