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.

IPCC opens registration for expert review of draft report
The Intergovernmental Panel on Climate Change (IPCC)—the United Nations body established to assess the science related to climate change—is offering experts an opportunity to review the draft version of its Sixth Assessment Synthesis Report.
IPCC assessment reports are published every six to seven years. The Fifth Assessment Report, completed in 2014, provided the main scientific input to the 2015 Paris Agreement.
Interested experts can register for participation in the review here. Registration is open through March 13. The review period ends on March 20.

Because of their good behavior under irradiation, fuel elements based on U3Si2 particles dispersed in an Al matrix have been used to convert to low-enriched uranium in a large number of research reactors. This behavior is extended to any compound grown by interdiffusion between silicide and Al during the fabrication process.
In this work, two plates fabricated with U3Si2 particles dispersed in an Al matrix were analyzed by optical and scanning electron microscopies, wave length dispersive microanalysis, and X-ray diffraction after the fabrication process. The results show that U(Al,Si)3 together with another phase with the same crystalline structure as U3Si2 but modified cell volume was formed.
A detailed analysis of fuel elements based on U3Si2 is considered very useful to be applied when going into greater depth in the frame of a U(Mo) qualification program.
