Can hydrogen be the transportation fuel in an otherwise nuclear economy?
Let’s face it: The global economy should be powered primarily by nuclear power. And it probably will by the end of this century, with a still-significant assist from renewables and hydro. Once nuclear systems are dominant, the costs come down to where gas is now; and when carbon emissions are reduced to a small portion of their present state, it will become obvious that most other sources are only good in niche settings. I mean, why use small modular reactors to load-follow when they can just produce that power instead of buffering it?

Inertial confinement fusion capsules must be manufactured with a high degree of azimuthal symmetry to avoid degradation by Rayleigh-Taylor instabilities. Therefore, the azimuthal fluctuations of each capsule must be characterized. We have developed a precision radiography method capable of measuring X-ray optical depth fluctuations to 1 part in 104 with a spatial resolution of 120 m. Achieving the measurement accuracy requires counting many photons.Recent measurements of glow discharge polymer (GDP) capsules show that the high X-ray intensity required to minimize measurement time modifies the GDP shell by increasing the oxygen atomic percent. An equatorial band forms that is more optically dense than the remainder of the capsule. We believe that free radicals are formed in the GDP as a result of the X-ray exposure. These free radicals preferentially absorb oxygen from the air. We will discuss how this optically dense band forms, how it is measured, and possible solutions to this issue.
