OECD NEA meeting focuses on irradiation experiments
Members of the OECD Nuclear Energy Agency’s Second Framework for Irradiation Experiments (FIDES-II) joint undertaking gathered from September 29 to October 3 in Ketchum, Idaho, for the technical advisory group and governing board meetings hosted by Idaho National Laboratory. The FIDES-II Framework aims to ensure and foster competences in experimental nuclear fuel and structural materials in-reactor experiments through a diverse set of Joint Experimental Programs (JEEPs).

Finite element modeling of the stresses in TRISO-coated fuel particles under normal operating conditions is undertaken with the ABAQUS code. Accurate results for the coating layer stresses are obtained with 30 finite elements in the model and ∼100 time steps through the life of the fuel. When compared to an earlier General Atomics/Forschungszentrum Jülich (GA/KFA) computer model of fuel performance, several discrepancies are uncovered in the earlier model. The GA/KFA model underpredicts the stresses in the silicon carbide layer, and the discrepancy increases with fission gas pressure.
