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.

Gamma radiation from point sources of cobalt-60 (1.25 Mev) and iridium-192 (0.4 Mev) was scattered from a concrete surface. Dose rates were measured at heights equal to source heights, as a function of the ratio of height to separation distance. The percent of scattered to direct radiation rises to a maximum of 12% at h/d = 0.10 for cobalt-60, and a maximum of 20% at h/d = 0.15 for iridium-192. These results are shown to agree with other work and with Monte Carlo calculations.
