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.

An equation is derived to estimate the perturbing effects on the neutron spectrum caused by a spectrometer inserted in an experimental assembly. This equation is applied to estimate the spectrum perturbation by a miniature NE-213 fast neutron spectrometer in a graphite assembly. The results show that the perturbation effect is smaller than the experimental errors and uncertainties, and that the effect caused by the neutron-sensitive volume is smaller than that caused by the surrounding materials.
