ANS joins others in seeking to discuss SNF/HLW impasse
The American Nuclear Society joined seven other organizations to send a letter to Energy Secretary Christopher Wright on July 8, asking to meet with him to discuss “the restoration of a highly functioning program to meet DOE’s legal responsibility to manage and dispose of the nation’s commercial and legacy defense spent nuclear fuel (SNF) and high-level radioactive waste (HLW).”

An explicit solution for stresses and strains in pyrolytic-carbon coatings on spherical fuel particles is presented. The resulting model is a modification of the Prados-Scott model which accounts for stresses arising due to anisotropic, radiation-induced dimensional change and the buildup of internal fission gas pressure, and for stress relaxation due to radiation-induced creep. Finite displacements are shown to amplify the effects of anisotropic dimensional changes. The use of the explicit solution allows a reduction in computation time by several orders of magnitude. The reduction in computation time makes feasible the use of Monte Carlo analyses (which have previously been precluded by high computation costs) to establish the effects of random variations in coated-particle parameters.
