I assisted nuclear engineering graduate students in running experiments to test the affects of different cooling systems on materials. I was involved in the development and running of a molten lead cooling loop, a supercritical water, and a CO2 experiment. For these projects I would ensure that they were running smoothly and troubleshoot any issues that arose. Additionally, I would prepare metal samples for testing by polishing them and would help prepare the samples for analysis by using SEM… Show more I assisted nuclear engineering graduate students in running experiments to test the affects of different cooling systems on materials.
