Recent surveys confirm high levels of U.S. nuclear support
Surveys have consistently indicated that public support in the United States for the use of nuclear energy has been increasing in recent years. Four recent surveys continue to suggest that near-record-high numbers of Americans support nuclear energy. However, the survey results differ—sometimes widely—in the details of their findings.

Global MHD stability calculations using the PEST code have been carried out as part of the US ITER team's High Aspect Ratio Design (HARD) study. Approximately 15,000 cases have been evaluated both for global and local (ballooning) modes. In addition to aspect ratio variations [2.78 < A < 5], a range of shapes (1.4 < κ < 2.0, 0. < δ < 0.6) has been examined and the safety factor has been varied: q(0) was varied from 1.05 to 1.85 and qψ from 3.1 to 4.55. For global aspect ratio scaling, these results show no significant increase or decrease in the maximum Troyon parameter, within the level of variation imposed by profile differences: the scaling of the maximum Troyon parameter (g) is found to be independent of A, if optimal values are considered at each aspect ratio. Specific results for the HARD configuration (A = 4.0, κ = 2.0, δ = 0.4 and q = 3.1, 4) show that the grequired can be obtained with values of 1i(3) = 0.65 – 0.85 in both the ignition and steady state phases.
