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.

A high fidelity wall-resolved Large Eddy Simulation has been performed for the flow through a guide plate of a Control Rod Guide Assembly (CRGA) at a hydraulic Reynolds number of 10,000. The computational mesh contains more than 1 billion computational cells and the simulation is run over six flow passes, which corresponds to almost 1 million time steps. The pressure forces are computed for all the rods and their average and rms values analyzed. This simulation can be either used to validate coarser LES/URANS computations, to understand the origin of physical phenomena such as deformations and vibrations or to model the pressure load along a rod.
