Figure 12.
The panel a plot gives gas peak pressure in kilopascal against stress on the canister in kilopascal. F L 903 values range from about 5650 kilopascal at 5000 kilopascal to 6450 kilopascal at 5700 kilopascal. F U 910 values occur near 5100 kilopascal and 5250 kilopascal on the horizontal axis, with gas peak pressure near 5350 kilopascal and 5200 kilopascal. F C T occurs near 7100 kilopascal on both axes. Panel b gives applied gas pressure in kilopascal against total stress in kilopascal. Values increase along a unity trend from about 3000 kilopascal to above 60000 kilopascal.The relationship between gas peak pressure and radial stress on the canister for all gas injection tests in Lasgit: (a) data from Lasgit; (b) compilation of data from tests in bentonite, adapted from Graham et al.
