ANS is committed to advancing, fostering, and promoting the development and application of nuclear sciences and technologies to benefit society.
Explore the many uses for nuclear science and its impact on energy, the environment, healthcare, food, and more.
Division Spotlight
Thermal Hydraulics
The division provides a forum for focused technical dialogue on thermal hydraulic technology in the nuclear industry. Specifically, this will include heat transfer and fluid mechanics involved in the utilization of nuclear energy. It is intended to attract the highest quality of theoretical and experimental work to ANS, including research on basic phenomena and application to nuclear system design.

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.

A fundamental issue of a human reliability analysis (HRA) in a nuclear power plant is a lack of empirical data in terms of both human error probability (HEP) and lower level information of human performance that can be used to estimate HEPs. As an effort to resolve this issue, KAERI (Korea Atomic Energy Research Institute) developed a framework, called HuREX (Human Reliability data Extraction), for data collection and analysis from a simulator to generate HRA data such as HEPs or correlations between performance shaping factors (PSFs) and the associated HEPs. The HuREX provides guidance on unsafe act (UA) identification, method and process of data collection.
To do this, the development of a computerized software interface is required to systematically collect simulator-based human performance data and subsequently enter/analyze/quantify various data obtained from the simulator. In addition, HRA database is also needed to effectively store the data generated in this process. In this research, we developed HuREX analysis supporting interface for HRA practitioner effectively conduct HRA data analysis by integrating various raw data (e.g., audio-visual records, plant parameters, operator's action logs) collected from the simulator.
