Description
In nuclear area when the handling of the Plutonium is necessary, generally in a first approach a simulation with Cerium is done. This element has chemical similarities with the Plutonium. A recent investigation, aimed at the Thorium Utilization in Pressurized Water Reactor carried out by CDTN/CNEN (at that time NUCLEBRAS) on the Brazilian side and KFA-Juelich with the participating companies Siemens UB KWU and NUKEM on the German side, showed that Thorium could be utilized associated to the Plutonium. In this present work the achievement of (Th,Ce)O2 alloy was investigated using the Master Mix concept, in which a ThO2 powder was blended with (Th,13%Ce)O2 coprecipitated powder in order to get sintered pellets with mean composition of (Th,6%Ce)O2. The results were supported by sintering dilatometric tests in ThO2 and (Th,13%Ce) pellets. (author)
Abstract (Portuguese)
Investigou-se a viabilidade de obtencao da liga ceramica (Th,Pu)O2, atraves da liga (Th,Ce)O2, com o cerio simulando o plutonio. Esta simulacao, para trabalhos em laboratorio, e vantajosa do ponto de vista de manuseio e custo, ja que o plutonio deve ser manuseado em condicoes especiais (caixas de luvas). (autor)Files
