ANS publishes revised position statement on nuclear power safety

November 1, 2021, 7:00AMANS News

Commercial nuclear power has accumulated nearly 75 years and 19,000 reactor-years of operating experience around the globe. In that time, nuclear professionals “have developed a proven and effective state-of-the art approach to safety that is a model in any industrial setting, including in the development of next-generation nuclear technology,” states the American Nuclear Society’s Position Statement #51: Safety of Nuclear Power. The Board of Directors approved the revised position statement in October 2021, and it has just been published on the ANS website, replacing a position statement published in 2007.

Sandia expands software billed as “Swiss Army knife” of nuclear system safety

Researchers at Sandia National Laboratories have been expanding MELCOR—the severe accident modeling computer code used by the Nuclear Regulatory Commission to evaluate the safety of light water reactors—to study the small modular reactors and non-light-water advanced reactors that are under development. An article published in Sandia Lab News on August 27 describes in detail how MELCOR is being expanded to work with different reactor geometries, fuel types, and coolant systems.
