Difusão do gadolínio no combustível nuclear UO2 Diffusion of gadolinium in the UO2 nuclear fuel

Publikováno v: Cerâmica, Vol 52, Iss 323, Pp 143-148 (2006)

Coeficientes de difusão do gadolínio foram medidos em volume e em contornos de grão de pastilhas do combustível nuclear UO2. Entre 1505 e 1703 ºC, em atmosfera de hidrogênio, o coeficiente de difusão em volume pode ser descrito pela seguinte e

Phase transitions during artificial ageing of segregated as-cast U–Mo alloys

Autor: Paulo Roberto Cetlin, Ana Maria Matildes dos Santos, W. B. Ferraz, Tércio Assunção Pedrosa, Fernando Soares Lameiras

Publikováno v: Journal of Nuclear Materials. 457:100-117

U–Mo alloys are a promising alternative in high-density fuel materials for use in research and test reactors, due to its resistance to swelling associated with the presence of the metastable γ-phase in the microstructure. It has been reported that

Synthesis and investigation of the luminescent properties of carbon doped lanthanum aluminate (LaAlO3) for application in radiation dosimetry

Autor: W. B. Ferraz, Luiz O. Faria, Neriene Alves

Publikováno v: Radiation Measurements. 71:90-94

LaAlO3 single crystals grown under hydrothermal conditions and co-doped with Ce and Dy atoms have been recently reported to show high thermoluminescent (TL) outputs for ultraviolet (UV) radiation fields ( Oliveira et al., 2011 ). Due to this property
