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.

El Salvador: Looking to nuclear
In 2022, El Salvador’s leadership decided to expand its modest, mostly hydro- and geothermal-based electricity system, which is supported by expensive imported natural gas and diesel generation. They chose to use advanced nuclear reactors, preferably fueled by thorium-based fuels, to power their civilian efforts. The choice of thorium was made to inform the world that the reactor program was for civilian purposes only, and so they chose a fuel that was plentiful, easy to source and work with, and not a proliferation risk.
Nuclear Criticality Safety Division Topical Meeting (NCSD 2022)
Plenary and Panel Session
Thursday, June 16, 2022|8:00–9:45AM PDT|Laguna A
Patterned after the highly successful closing plenary of ICNC 2019, the closing plenary of NCSD 2022 will provide a forum for each of the leaders of the 10 different technical tracks to present an overview of the papers discussed in their sessions share any emerging issues or themes with the broader NCS community. Each track representative will give a 5-10 minute highlight discussion. The meeting will be closed with preview presentation on ICNC 2023, which will be held in October of 2023 in Sendai, Japan.
Track 1: Lessons Learned in Nuclear Criticality Safety- Accidents, infractions, and lessons learned.
Track 2: Decontamination and Decommissioning- Recovery, restoration, and their respective challenges.
Track 3: Interesting Anomalies in Nuclear Criticality Safety- Non-intuitive phenomena, unexpected results, and interesting stories.
Track 4: Operational Practices- Operational criticality safety activities and applications.
Track 5: Fuel Storage, Transportation, and Disposal- Burnup credit, transportation needs, and storage issues.
Track 6: Experiments and Benchmarks- Measurements, experiments, and benchmarks.
Track 7: Codes, Data, and Methods- Analyses, validation, and sensitivities/uncertainties.
Track 8: Nuclear Criticality Safety for LEU+/HALEU- Response to growing needs for increased uranium enrichment.
Track 9: Knowledge Transfer- Education, Professional Development, and Training.
Track 10: Innovative Technologies and Thinking- Machine learning, Artificial Intelligence, etc.
