New polls show substantial support for nuclear energy
Sixty percent of respondents in a recent national survey favored the use of nuclear energy, with only 25 percent opposing its use. While the latest Bisconti Research poll focuses on nuclear power and electricity generation, its findings on public interest in climate change and using a spectrum of sources to meet energy needs are consistent with a recent Pew Research Center poll on a broad set of energy policy and climate change topics. The approaches the two online surveys took to measuring public opinion on nuclear energy yielded different numbers but found some common ground.

A new method to diagnose the degree of electron degeneracy in compressed fuel for fast-ignition inertial confinement fusion is proposed. We focus on 4.44-MeV -rays emitted in the reaction 9Be(,n)12C governed by fusion-produced energetic alpha-particles in a laser-imploded DT fuel pellet admixed with a small amount of 9B. In this case the compressed fuel pellet is not subjected to any heating laser pulse. We have evaluated the probability P-Be that the + 9Be reaction occurs during the slowing down of -particle. It is found that the reaction probability depends strongly on the degeneracy parameter , which is defined as the ratio of electron temperature to the Fermi energy. We show the possibility of diagnosing the electron degeneracy from the P-Be - diagram by detecting the 4.44-MeV -quanta and DT neutrons emitted from the dense core plasma.
