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.

An evaluation of a fluted tube, counter-flow heat exchanger (HEX), designed and optimized for heat transfer from the primary loop of a fast chloride salt reactor to an intermediate loop, is presented. The fluted-tube HEX was optimized for volume and pressure drop by altering tube length, flute number and pitch, and tube diameter for multiple commercially available fluted tubes. Three compositions of molten NaCl-KCl-ZnCl2 salt are used in the analysis. A fluted tube HEX design and salt composition are recommended and the HEX performance and physical size are compared to a conventional tube and shell HEX designed with tubes of equivalent diameter and length. Design of a fluted tube HEX and salt composition have the potential to improve the performance of Molten Chloride Salt Fast Reactors (MCSFRs). The MCSFR referenced in this evaluation is being developed by Elysium Industries and is a leading candidate for commercial deployment.
