Major effort during the report period was expended on the preparation and characterization of samples scheduled for in-pile screening tests. Other activities were continued on installation of hot metallographic cell installation and preparation and evaluation of UO/sub 2/-PuO/sub 2/ coprecipi tation processes. Data obtained in three preparation runs are included. A steady state intermediate production run was used to study the effects of ammonia evolved during the initial stages of mixed oxide precursor conversion on ADU precipitation. To determine whether or not selfreduction occurs, charges of the precursor were thermally decomposed in N/sub 2/ using fast and slow temperature rises on similar samples. Results are included which indicate that no significant amount of self-reduction occurs under these conditions. Effort is also continuing on development of techniques for producing spherical particles by mechanical agglomeration and sintering, and by plasma torch fusion. (J.R.D.)
