Abstract

To improve the in pile behavior of U(Mo) dispersion fuel, adding Si to the meat has proven to be beneficial to limit the unwanted interaction between the U(Mo) fuel and the Al matrix and to improve the properties of the interaction phase. Currently, in several irradiation programs, Si is added to the Al matrix either as mixture or alloy element. However, recently SCK•CEN has succeeded to produce Si and ZrN coated U(Mo) particles. To investigate the influence of these coatings and the dispersion of the Si in the meat on the interaction between the U(Mo) and Al of the matrix, out-of-pile studies have been performed on pressed coupons containing U(Mo) (coated and uncoated) particles dispersed in a Al(Si) matrix
