Leak-tightness test on deck for SRS mega unit
The Savannah River Site in South Carolina will begin a leak-tightness test to qualify the megavolume Saltstone Disposal Unit (SDU) 10 to store up to 33 million gallons of solidified, decontaminated salt solution produced at the site.

The feasibility of using spark source mass spectrography for a direct multielement analysis of solid sodium is demonstrated. Two different sparking configurations are employed, one with the capability of obtaining local analyses and the other capable of bulk analyses. Sample handling and preparation are minimal. Both argon and vacuum are used to protect the sodium prior to analysis. Liquid nitrogen cooling applied to the sodium while sparking inhibits melting and preferential volatilization. Detection limits below 100 ppb atomic are readily attained, and there is reasonable agreement with emission spectrographs results. The analysis of doped solutions further confirms the applicability of the technique.
