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.

Smarter waste strategies: Helping deliver on the promise of advanced nuclear
At COP28, held in Dubai in 2023, a clear consensus emerged: Nuclear energy must be a cornerstone of the global clean energy transition. With electricity demand projected to soar as we decarbonize not just power but also industry, transport, and heat, the case for new nuclear is compelling. More than 20 countries committed to tripling global nuclear capacity by 2050. In the United States alone, the Department of Energy forecasts that the country’s current nuclear capacity could more than triple, adding 200 GW of new nuclear to the existing 95 GW by mid-century.
Radiation Protection and Shielding Division 2024 (RPSD 2024)
Ms. RaJah Mena is currently employed by Mission Support and Test Services, the Management and Operations contractor for the Nevada National Security Site (formerly the Nevada Test Site). She manages the Consequence Management (CM) program at the Remote Sensing Laboratory at Nellis Air Force Base. The major focus of the program is to staff and manage the CM assets on behalf of the Department of Energy, the lead agency in the Federal Radiological Monitoring and Assessment Center (FRMAC), the organization providing federal support to a nuclear or radiological response. In addition to program management, she also serves on several technical deployment and home team positions for the CM and Aerial Measuring System response teams. During her 18 years with the contract, Ms. Mena has developed equipment tests, designed, and executed numerous drills and exercises, contributed to and co-authored national-level policy documents, and responded to several real-world events including the US response to the Fukushima Dai-ichi nuclear power plant incident in Japan (2011).
Ms. Mena holds Bachelor of Science and Master of Science degrees in Health Physics from the University of Nevada, Las Vegas.
