Analytical stress analysis solution for a simplified model of a reactor fuel element. Final report

“…The release process is governed by complex diffusion mechanisms, and computer programs such as LIFE [7] and FMODEL [8] include detailed models for the prediction of release rates. These considerations are outside the scope of the present analysis, and a much more simplistic approach is adopted.…”
