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.

In a tritium handling facility it is important to know the volume of the parts of the system for accurate accountancy. The usual methods to determine volumes have several disadvantages concerning contamination issues and accuracy.In this work a novel method is used to determine volumes. The method does not require any liquid or precisely known reference volume. It is simple and the uncertainty of the measurement is lower than 1% for volumes from 10 cm3 to 10 dm3.In this paper the principle of the volume determination device (VDD) designed and built at the Tritium Laboratory Karlsruhe (TLK) is presented, together with a detailed uncertainty calculation. Also the first measurements with the VDD are discussed in detail.
