MINIATURE BOILER TEST--NaK INJECTION (NO. 2). Memo Report 125
Technical Report
·
OSTI ID:4274745
A test was run to determine the effect of a slow NaK leak to the water side nozzle where temperature measurements indicated the presence of superheated steam. Approximately 110 grams (0.242 lbs) was injected over a period of 61/2 hours with no indication of a temperature rise due to the water-NaK reaction. The boiler was operated 18 hours after the NaK injection was started before a steam leak was noticed. The system was immediately secured, allowed to cool and the boiler removed from the system. Several cracks were visible in the shell at this time. The unit was then returned to B & W for metallurgical examination. Preliminary examination revealed cracks in both the shell and outer tube.
