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.

The influence of a few parameters on the possibility of reaching ignition in the Ignitor device is analyzed using a 1½-dimensional equilibrium transport code. The models adopted for electron and ion thermal diffusivities scale with the net power input to the plasma components. No auxiliary heating is considered besides that due to alpha particles. In the operative scenario examined, the plasma current (Ip = 10 MA) and the toroidal field (BT = 11.1 T) are maintained for 4 s. The importance of density profile shaping is pointed out together with the influence of current density peaking. Sensitivity to specified assumptions is also analyzed and the limit values, still guaranteeing ignition, for different parameters are determined.
