DOWNLOAD EBOOKThe scope of this work is to present an evaluation of the postirradiation examination of the second set of high-U-loaded low-enriched U3O, UAl2 and U3Si miniature plates manufactured by the Comision Nacional de Energia Atomica (CNEA) of Argentina, and irradiated and examinated, within the framework of the Reduced Enrichment Research and Test Reactor (RERTR) Program, at Oak Ridge National Laboratory and Argonne National Laboratory. This paper includes fabrication details of the plates, their irradiation history and the results of postirradiation examination which are compared to those of the previous test and to present results from other laboratories participating in the RERTR Program. Postirradiation examination of these plates showed satisfactory poerformance for the oxides, aluminides and silicides (except for the highest-loaded U3Si plate) with the only indication of detrimental behavior during the slight bowing of some plates at about 80% burnup.
