Atomic Scale Studies of the Stress Effects on Defect Kinetics and Damage Evolution of Irradiated Fe Kang, Changwoo (2018-01-11)Irradiation of the materials with neutrons or energetic particles creates a significant number of point defects and nucleates extended defects, such as dislocations and voids. These defects result in the changes of material ...
-
Tang, Xiaodong (2021-11-01)In this work, a barium fluoride (BaF₂) scintillation detector is investigated to determine if it can be used for fast measurement of deep burn fuel in advanced reactor designs. Pebble bed high-temperature gas-cooled reactors ...
-
Helmreich, Grant (2012-02-14)The sintering behavior of uranium and uranium-zirconium alloys in the alpha phase were characterized in this research. Metal uranium powder was produced from pieces of depleted uranium metal acquired from the Y-12 plant ...
