An Experimental And Numerical Investigation Of Flow Accelerated Flibe Corrosion, David B. Weitzel

Nuclear Engineering ETDs

Renewed interest in molten salt reactor technology has brought to light the need for a better understanding of FLiBe corrosion. To this end a flowing FLiBe corrosion test loop was designed to test the flow effects of FLiBe corrosion. The loop consists of a pump, melt tank, and stainless-steel tubing assembly that heats the molten salt to high temperatures and circulates it over test specimens. The experiment has been constructed and has completed initial shakedown testing.

To support the flowing FLiBe experiment, a numerical corrosion model that couples FLiBe electrochemistry, solid metal diffusion, and mass transport was implemented. The model …

Electrochemical Investigation Of Homogenous Species At An Electrode Interface, Christopher Larsen Iii

CO2 reduction is a pressing problem worldwide, and one obstacle in the electrochemical conversion of CO2 to more useful C1 products such as methanol and formic acid is the kinetic barrier known as overpotential. The overpotential of rearranging the nuclei in CO2 to accommodate electron transfer can be lowered by pre-bending the CO2 molecule in an adduct-mediated complex. The work presented in Part I utilizes a combination of hard and soft donors on pincer-like ligands to effect the bending of CO2 prior to electrochemical reduction. A large majority of the work consists of using Group 4 metallocenes, but Chapter 3 …
