ABSTRACT:
In one aspect the method provides for determining changes in helium concentration over time in the interstitial space between a primary vessel that is charged with helium and a secondary vessel. The expected concentration resulting from permeation is calculated and accounted for. In another aspect, air is circulated in the interstitial space. An abrupt change in measured concentrations may be used to determine an approximate leak location.
