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.

An experiment on the separation of hydrogen isotopes has been carried out by using a thermal diffusion column with a “cryogenic-wall” cooled by liquid nitrogen. The separation factor was compared with that of a ordinary column cooled by water, and the separation factor for the “cryogenic-wall” column is higher than that for the “water cooled wall” column. Moreover, the separation factor obtained by a 473 K operation of the hot wire in the “cryogenic-wall” system was found to be greater than that by 1073 K operation. Probably because the isotopic exchange reaction between H2 and D2 was suppressed in 473 K operation; there was no HD component observed in this case, while an equilibrium amount of HD component was immediately detected in 1073 K operation.
