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 expected value of nuclear spin polarization to inertial confinement fusion is recapitulated. A comparison of brute force polarization versus dynamic nuclear polarization, as applied to solid deuterium-tritium, is given, and the need for a long triton polarization memory time (longitudinal nuclear relaxation time) is shown. The time constant for 25 mol%T2-50 DT-25 D2 (D-T) is a short 0.3 s at 5 K and waiting in the presence of tritium radioactivity lowers it to 0.1 s. Enriched 90 to 96% molecular DT has been synthesized and held 3 to 4 hours at 10 K, which lowers the overall J=1 T2 concentration to about 0.1%. The resulting memory time can be raised in this way to 0.7 to 0.8 s. These samples were then melted and nHp added, which increased the memory times to 6 to 8 s - an increase of twenty-fold over regular D-T at 5 to 6 K. The theory shows that the species shortening the triton memory time is the J=1 T2, which can be reduced in our samples only by radioactive self-catalysis. Cryogenic distillation is considered as a possible means of removing the J=1 T2 from molecular DT.
