Abstract The growth and interconnection of fission gas bubbles in the hotter central regions of U-(Pu)-Zr nuclear fuel has been simulated with a phase-field model. The Cahn-Hilliard equation was used to represent the two-phase microstructure, with a

Variance-based sensitivity analysis applied to hydrogen migration and redistribution model in Bison. Part I: Simulation of historical experiments

Autor: Giovanni Pastore, Zineb Aly, Nicholas R. Brown, Albert Casagranda

Publikováno v: Journal of Nuclear Materials. 524:90-100

In a light water nuclear reactor environment, zirconium-alloy cladding undergoes corrosion that introduces hydrogen into the cladding. Hydrogen being slightly soluble in zirconium means that the terminal solid solubility of hydrogen is quickly reache

Variance-based sensitivity analysis applied to the hydrogen migration and redistribution model in Bison. Part II: Uncertainty quantification and optimization

Autor: Nicholas R. Brown, Albert Casagranda, Zineb Aly, Giovanni Pastore

Publikováno v: Journal of Nuclear Materials. 523:478-489

We demonstrate a global sensitivity and uncertainty analysis approach to quantify the impact of uncertainty in the hydrogen migration and redistribution models implemented in the U.S. Department of Energy Office of Nuclear Energy fuel performance cod

Fuel relocation recovery implementation in Bison

Autor: Mudasar Zahoor, Albert Casagranda

Publikováno v: Journal of Nuclear Materials. 511:473-479

During the initial rise to power in light water reactors (LWR), thermal gradients within a pellet cause radial and axial cracks to form in the fuel. The effect of these cracks is to reduce the pellet-cladding gap and accelerate the interaction betwee
