Abstract

We show that a homogeneous single-phase mixed oxide is obtained by blending and sintering commercial UO 2 and nanocrystalline PuO 2 powder; whereas, under the same conditions, conventional PuO 2 powder obtained from oxalate precipitation and composed of platelets, yields two-phase mixed oxide. The use of nanometric PuO 2 results in a larger final grain size.
