Chernobyl at 40 years: Looking back at Nuclear News
Sunday, April 26, at 1:23 a.m. local time will mark 40 years since the most severe nuclear accident in history: the meltdown of Unit 4 at the Chernobyl nuclear power plant in Ukraine, then part of the Soviet Union.
In the ensuing four decades, countless books, documentaries, articles, and conference sessions have examined Chernobyl’s history and impact from various angles. There is a similar abundance of outlooks in the archives of Nuclear News, where hundreds of scientists, advocates, critics, and politicians have shared their thoughts on Chernobyl over the years. Today, we will take a look at some highlights from the pages of NN to see how the story of Chernobyl evolved over the decades.

The influence of temperature and gas composition on hydrogen isotope separation factors of membrane cascade with reflux ratio of 0.9998 and different palladium alloy membranes were studied. Separation factors for H-D mixture with different palladium alloy membranes varies from 1.31 to 1.42 at different temperatures, and for H-D-T mixture with Pd-8.6%Y alloy membrane, the factors are 1.2 to 2.0 at different temperatures. The results suggest advantages of operating the cell at high temperature because the higher permeation rate and separation factor at high temperature will lead to a great decrease in the separation stages and membrane area of a separation unit.
