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.

INL’s new innovation incubator could link start-ups with an industry sponsor
Idaho National Laboratory is looking for a sponsor to invest $5 million–$10 million in a privately funded innovation incubator to support seed-stage start-ups working in nuclear energy, integrated energy systems, cybersecurity, or advanced materials. For their investment, the sponsor gets access to what INL calls “a turnkey source of cutting-edge American innovation.” Not only are technologies supported by the program “substantially de-risked” by going through technical review and development at a national laboratory, but the arrangement “adds credibility, goodwill, and visibility to the private sector sponsor’s investments,” according to INL.

COSYMA (COde SYstem from MARIA) is a new program package for assessing the off-site consequences of accidental releases of radioactive material to atmosphere, developed as part of the Commission of the European Communities Methods for Assessing the Radiological Impact of Accidents (MARIA) program. It represents a fusion of ideas and modules from the program system UFOMOD from Kernforschungszentrum Karlsruhe, the program MARC from the National Radiological Protection Board, new model developments, and data libraries from other MARIA contractors. The flexible coding permits a problem-oriented application to different sites, source terms, emergency plans, and needs of users in the various parts of Europe. An overview is given of the structure, models, and endpoints of COSYMA.
