      As a graduate research assistant I worked in Texas A&M's nuclear Fuel Cycle and Materials Laboratory (FCML), and at the Nuclear Science Center (NSC). My work in the FCML was focused on, "Hydrogen Interactions in Zirconium Alloys for Nuclear Applications." I developed a cathodic charging system, to insert hydrogen in two alloys, Zicaloy-4 and HANA-4 (a Zr-Nb-Fe alloy). Charged specimens were annealed at select temperatures, in order to evaluate these alloys over a range of hydrogen concentrations, corresponding to high burnup nuclear fuel.. Charged samples, pre and post annealing, were analyzed via XRD and SEM to characterize the hydride phase(s) and structure formed in the alloy. Texas A&M's Nuclear Science Center is home to a 1 MW TRIGA research reactor. At the NSC I was given the task of writing a project safety analysis for laboratory research activities. This involved becoming familiar with the work performed and identifying the hazards associated with each task. Show less
