A Compact, Convective Flow Nak Test Loop For Material Exposure Contained In An Argon Atmosphere, David Joseph Rowekamp
A Compact, Convective Flow Nak Test Loop For Material Exposure Contained In An Argon Atmosphere, David Joseph Rowekamp
Masters Theses
The objective of this research project was to construct a compact NaK loop to test weld configurations for application in a space reactor. The NaK loop fits inside of standard welding glove-box, and holds 64 weld specimens and a diffusion bonded tube-plate assembly. The NaK loop has a furnace which operates at a 650 degrees Celsius. It contains two independent and by-passable cold traps to maintain low oxygen levels in the NaK. The loop also contains a coil heat exchanger to cool the NaK. The loop operates with purely with convective flow, which is driven by the temperature differential between …
Simulations Of Ti-Y-O Nanoclusters In Ferritic Alloys, Natalie Browning Camilli
Simulations Of Ti-Y-O Nanoclusters In Ferritic Alloys, Natalie Browning Camilli
Masters Theses
Nanostructured ferritic alloys possess high strength and resistance to radiation effects due to the presence of nanoprecipitates. Though nanostructured ferritic alloys have desirable mechanical properties, the exact composition and structure of the nanoprecipitates is unknown; thus, atomistic simulations involving the formation of nanoclusters give insight as to their structure. This thesis focuses on the structure, formation and radiation stability of Ti-Y-O [titanium-yttrium-oxygen] nanoclusters in iron. The activation energies for diffusion and the diffusion coefficients of oxygen interstitial atoms in iron are determined. The binding energies of various combinations of oxygen interstitial atoms and iron vacancies are also tabulated. Thermodynamic formation …
