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).

Hydrolysis constants of the zinc ion were measured at 25, 50, 75, 185, 200, and 225°C through the direct measurement of pH using pH sensors, especially of the yttria-stabilized zirconia membrane-type in the case of high temperatures over 185°C, and evaluation was done on the temperature dependence of the hydrolysis constants of the zinc ion. Solubilities of zinc oxide in pure oxygenated water were measured at 150, 200, and 250°C. Equilibrium constants of zinc oxide dissolution and the values of Gf0(Zn2+) at each temperature were estimated by thermodynamic analysis applying the estimated hydrolysis constants to the solubility data of ZnO.
