ANS announces 2025 Presidential Citations
One of the privileges of being president of the American Nuclear Society is awarding Presidential Citations to individuals who have demonstrated outstanding effort in some manner for the benefit of ANS or the nuclear community at large. Citations are conferred twice each year, at the Annual and Winter Meetings.
ANS President Lisa Marshall has named this season’s recipients, who will receive recognition at the upcoming Annual Conference in Chicago during the Special Session on Tuesday, June 17.

The Fukushima accident suggests that serious consideration must be given to changing current safety goals to properly address the major impacts of nuclear accidents on society, including health effects, property damage, and environmental contamination. Based on lessons learned from the Fukushima accident, a conceptual design and a new approach for implementing prevention and mitigation measures for severe accidents are proposed. Instead of an optimistic view on the progression of a severe accident and available resources, a worst-case scenario is considered to prepare for an unexpected situation. With a safety goal of practically eliminating the significant release of radioactive material, an improved approach for a prevention and mitigation strategy is proposed. This approach consists of a new severe accident management strategy with dedicated mitigation measures and suitable essential instrumentation to take timely recovery actions. The approach is designed to be more robust and resilient than the conventional system.
