| Abstract Scope |
In order to facilitate the short-term design and construction of Molten Salt Reactors, cladding systems have been proposed for codified alloys as a methodology to mitigate the effects of corrosion and extend the lifetime of structural materials. This work focuses on the corrosion performance in molten fluoride salt of cladding systems on 316H stainless steel in a static isothermal corrosion cells. These systems include nickel-weld overlay, nickel electroplating, and molybdenum hot isostatic press and, diode laser cladding diode laser cladding processes. Corrosion was performed for 1000 hours at 700°C in purified molten FLiNaK salt. In addition, thermal aging tests were performed in parallel in an inert atmosphere. The pre- and post- corrosion cladding and cladding/substrate interface were characterized using SEM, EDS, XRD, and micro hardness techniques. Experimental results of interface diffusion were compared to the ones obtained from CALPHAD simulations in order to predict cladding degradation at longer exposure times. |
