Going Nuclear: Notes from the officially unofficial book tour
I work in the analytical labs at one of Europe’s oldest and largest nuclear sites: Sellafield, in northwestern England. I spend my days at the fume hood front, pipette in one hand and radiation probe in the other (and dosimeter pinned to my chest, of course). Outside the lab, I have a second job: I moonlight as a writer and public speaker. My new popular science book—Going Nuclear: How the Atom Will Save the World—came out last summer, and it feels like my life has been running at full power ever since.

We performed an experiment of H and D permeation through Li17Pb83 in the two-component (H+D) system by an unsteady permeation method to clarify interactions between H and D atoms. It was found that H and D permeate independently regardless of the H/D composition ratio in the upstream gas. Dissolution of H and D atoms into Li17Pb83 follows the Sieverts' law in the two-component system in a similar way to the single one. Diffusion of H and D in Li17Pb83 was the rate-determining step in the overall permeation process. An isotope effect of permeability between H and D was around 1.4 in the temperature range from 400°C to 700°C. The ratio of the isotope effect was in proportion to the square root of mass ratio of D to H. Tritium permeation can be estimated in a similar way.
