Abstract
Production of UO.sub.2 nuclear fuel pellets containing PuO.sub.2 in set amounts, which pellets are soluble in nitric acid and suitable for reprocessing without the aid of a special additive. Uranium oxide powder is mixed with 15 to 50% by weight of the mixture of plutonium oxide powder; the mixture milled and pressed into pellets. The pellets are sintered, comminuted, pressed to form pellets and the pellets comminuted to free-flowing granules. The free-flowing granules are mixed with UO.sub.2 granules to obtain a desired UO.sub.2 /PuO.sub.2 ratio, and the mixture pressed into pellets and sintered to form UO.sub.2 nuclear fuel pellets containing PuO.sub.2 soluble in nitric acid.
