Towards a physics-based description of intra-granular helium behaviour in oxide fuel for application in fuel performance codes

Towards a physics-based description of intra-granular helium behaviour in oxide fuel for application in fuel performance codes

In this work, we propose a new mechanistic model for the treatment of helium behaviour which includes the description of helium solubility in oxide fuel. The proposed model has been implemented in SCIANTIX and validated against annealing helium release experiments performed on small doped fuel sampl...
