Physically based model for helium release from irradiated boron carbide

Physically based model for helium release from irradiated boron carbide [electronic resource]

The model is based on the nucleation of nonequilibrium helium bubbles under high pressures. The bubbles subsequently act as traps and grow as the result of gas atom diffusion. Model predictions are compared with bubble densities, sizes, and helium release characteristics of irradiated boron carbide.
