We welcome ANS members who have careered in the community to submit their own Nuclear Legacy stories, so that the personal history of nuclear power can be captured. For information on submitting your stories, contact nucnews@ans.org.

As an undergraduate I studied physics at the University of Athens. I entered the university in 1955 after successfully passing a national exam (came up fourth in a field of about 700 candidates). Upon graduation and finishing my mandatory two-year military service, the plan was to teach physics either in a public high school or as a tutor for a private for-profit institution, preparing high school students for the national exam.

Nuclear Technology searches for a new technical editor

August 8, 2022, 3:00PMANS News

At the recent ANS Annual Meeting, Andrew Klein, past ANS president (2016–2017), professor emeritus of nuclear science and engineering at Oregon State University, and the current editor of ANS’s journal Nuclear Technology, announced his retirement at the end of his term in June 2023. ANS is looking for qualified members who are interested in becoming the next technical editor of the journal. The selected person will be appointed “editor-designate” and will work with Dr. Klein for a period of time before taking over the full editor’s role.

Klein, professor emeritus at Oregon State University and past ANS president, took over the duties of technical editor in 2015, a few years before his term as ANS president. During his tenure as editor, Dr. Klein has raised NT ’s reputation for technical excellence and arranged a schedule of twelve issues annually covering the most important topics in nuclear technology.

Pebble bed reactors, friction, and cooling

When one of the largest modern earthquakes struck Japan on March 11, 2011, the nuclear reactors at the Fukushima Daiichi nuclear power plant automatically shut down as designed. The emergency systems, which would have helped maintain the necessary cooling of the core, were destroyed by the subsequent tsunami. Because the reactor could no longer cool itself, the core overheated, resulting in a severe nuclear meltdown.

Since then, reactors have improved exponentially in terms of safety, sustainability and efficiency. Unlike the light-water reactors at Fukushima, which had liquid coolant and uranium fuel, advanced reactors have a variety of coolant options, including molten-salt mixtures, supercritical water, and gases such as helium.

Frequently the three international research journals published by ANS dedicate issues to special topics or selected top papers presented at conferences. In celebration of Nuclear Science Week, here’s a recap of the research highlights published by Nuclear Science and Engineering (NSE), Nuclear Technology (NT), and Fusion Science and Technology (FST) in 2020 (ANS members get free subscriber access):
