Sampling and characterization of sodium-water reaction products

PDF Version Also Available for Download.

Description

Sodium-water reaction products (SWRP) which had accumulated in the bottom of the reaction products tank (RPT) of the Large Leak Test Rig (LLTR) were sampled and characterized. Analysis showed that the SWRP consisted of NaOH, Na/sub 2/O, NaH, and Na, as expected, in varying proportions. The unreacted sodium in the samples examined ranged from 32 to 60% by weight. The SWRP reacts (dissolves) rapidly and completely with ethanol, and somewhat less rapidly and completely with Dowanol PM. A magnetic, metallic residue was left, originating in the Croloy of the test article in the LLTR. These solvents should be investigated further ... continued below

Description

Sodium-water reaction products (SWRP) which had accumulated in the bottom of the reaction products tank (RPT) of the Large Leak Test Rig (LLTR) were sampled and characterized. Analysis showed that the SWRP consisted of NaOH, Na/sub 2/O, NaH, and Na, as expected, in varying proportions. The unreacted sodium in the samples examined ranged from 32 to 60% by weight. The SWRP reacts (dissolves) rapidly and completely with ethanol, and somewhat less rapidly and completely with Dowanol PM. A magnetic, metallic residue was left, originating in the Croloy of the test article in the LLTR. These solvents should be investigated further as possible agents for cleaning sodium systems that are highly contaminated with water reaction products. The SWRP does not completely liquefy with heating to 800/sup 0/F (427/sup 0/C). Although it softens to a consistency similar to that of wet sand, it is unlikely that it would flow or could be pumped even at such elevated temperature. The presence of highly corrosive molten NaOH. (above 606/sup 0/F, 319/sup 0/C) also makes the hot draining of SWRP unattractive.
