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.

Tank waste operations resume at Idaho’s IWTU
The Department of Energy’s Office of Environmental Management announced yesterday that waste processing operations have resumed at the Integrated Waste Treatment Unit (IWTU) at the Idaho National Laboratory Site. The resumption of operations follows the completion of two maintenance campaigns at the radioactive liquid waste treatment facility.

Risk assessment of a complex system that uses new technologies is described: the MegaJoule Laser (LMJ). The steps to obtaining the safety and security goals for LMJ are highlighted, i.e., to ensure safe operation, to put in place detection systems and means to prevent or limit serious accidents, and to limit the consequences to the environment and the workers. The objective is to show what has been done during LMJ design and construction to prevent serious accidents during routine operations and maintenance.The risks during operations and maintenance of the LMJ facility are identified by a preliminary risk analysis. The safety management to address adequately the protective features is described. As an example, a main accidental scenario in the LMJ target area is emphasized: workers' exposure to hazardous levels of nuclear radiation. The LMJ operation and maintenance safety requirements that must be taken into account by the industrial firms to which LMJ contracts have been awarded are discussed.
