Twenty scoping experiments were performed to investigate the behavior of nominally 0.5 g molten lithium drops when released into 0.7 L of the organic coolant Therminol 66 at local atmospheric pressure using a vortex insertion technique. Diagnostics consisted of video and photographic imaging and several chemical analyses. Six coolant/Li temperature pairs were used: 300/300; 300/530; 300/770; 464/530; 600/530 and 600/770, all nominal in K. Because the coolant: Li weight ratio was 103, only rapid (∼0.5 s) quenching reactions could be studied when TLi > Tc; when TLi ≤ Tc, however, both rapid and slower (min) interactions could be investigated. In none of the experiments was there any indication of (a) a vigorous, self-sustaining chemical reaction between the lithium and the organic coolant, or (b) the formation of water-insoluble debris, in particular carbon. Our work confirms the benign behavior at similar temperatures reported earlier by others.
