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.

Tritiated process water is monitored by detecting the D2O component via the 2D(γ,n)1H reaction. A probe containing a 1- to 7-mCi 24Na (15-h) gamma source and six 3He neutron detectors produces and monitors the 2D(γ, n)1H reaction. A variety of probe configurations were examined for D2O detection sensitivity. The corresponding detection limits range from 6 to 280 µl for D2O droplets and 1 to 13 µl/cm for D2O streams, when 10-min neutron counting with a 1-mCi gamma source is used. Results from two field applications illustrate the utility of the monitor.
