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).

The neutron shielding properties of ilmenite-magnetite (I-M) concrete are measured experimentally. The instantaneous relaxation length and thickness-dependent removal cross section of neutrons from a 252Cf source penetrating I-M concrete with and without a cadmium sheet are reported. An empirical formula is developed to calculate the thickness dependence of the removal cross section and the related coefficients are reported. The results illustrate the effectiveness of I-M concrete so far as its shielding properties are concerned. This material can be used to shield reactors, accelerators, X-ray installations, and radioactive sources used for commercial purposes.
