Disney World should have gone nuclear
There is extra significance to the American Nuclear Society holding its annual meeting in Orlando, Florida, this past week. That’s because in 1967, the state of Florida passed a law allowing Disney World to build a nuclear power plant.

Ion-driven permeation of deuterium was studied through an iron (0.1 mm thickness) coated with a SiO2 of about 30 nm thick. A flux ratio of permeation/incident for the Fe sample ranged from 7.6 × 10−5 at 373 K to 1.4 × 10−3 at 673 K for the incident ion flux of 6.4 × 10−18 ions m−2S−1 at the ion energy of 0.3 keV. The permeation flux through the back coated sample is lowered by a factor of 1 or 2 orders of magnitude than the case of the Fe sample. The activation energy(0.2eV) of the permeation of these two samples are almost same. As for the front coated sample, the different energy and incident ion flux dependences were observed. Investigations of the SiO2 coating property under deuterium ion implantation by XPS showed that the coating on the front surface could easily sputtered away during the experiments. Thus, the surface after removing of the coating has a special condition that changes the properties of permeation.
