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 method is developed for using standard discrete ordinates neutron transport codes to perform Fokker-Planck calculations in one-dimensional slab and spherical geometries. No modification of the codes is necessary and time-dependent, steady-state, forward, or adjoint calculations can be performed. It is shown that energy-angle integrated quantities such as energy and charge deposition profiles can be accurately and efficiently calculated for electrons. However, in certain types of problems, the number of groups required to converge the differential energy spectra can be prohibitively large.
