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).

Measurement of corrosion product radiation levels in the Fast Flux Test Facility heat transport system cells shows a buildup of just over 10 mrem/h in regions near the hot leg and >400 mrem/h near the cold leg. These levels are due to 54Mn only; mere traces of 60Co are observed. The basis for the model used to predict radiation level buildup is reviewed. The observed radiation levels and the predicted values are compared. Discrepancies and reasons for the discrepancies are noted and explained. Some possible changes in calculation methods to increase accuracy in future predictions are presented.
