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).

A simple rational-based model is developed to predict the pressure loss of a pressurized water reactor-type nonmixing vaned spacer grid. The total pressure loss is obtained by adding the form and friction losses. Elementary fluid-mechanical correlations are used to model each loss. The model reasonably predicts the available spacer grid loss data.
