Performed in frames of Russian RERTR Program were post-irradiation examinations of 12 types of disperse (U-Mo)-based fuel compositions in Al matrix. The goal of the work was to substantiate serviceability of the new fuel compositions being developed for utilization in Russian-built pool-type research reactors. Among the methods of PIE used in this work were visual examination, gamma-scanning, optical metallography, SEM, X-ray analysis and some others. The present paper is dedicated to an analysis of the main results of PIE completed so far. Special attention has been paid to the parameters affecting formation of interaction layer between fuel granules and matrix Al. (author)
