Sodium plus water yields fun (if you are careful).

Here are few slides. More later from this report. Click on the slide to enlarge, then you're back button to move on.







The above slide is a burnout test with a totally blocked channel. The entire assembly is immersed in water (an open topped 55 gallon drum). The induction coil is insulated from the water.



This slide shows the capsule after the burnout. The capsule has swelled from internal pressure. The expanded capsule broke through the Vycor tube and an arc from the induction coil led to the pinhole leak. The 40 grams of NaK was totally reacted, but the reaction was not violent. This presentation will be expanded.
