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.

Investment bill would provide funding options for energy projects
Coons
Moran
The bipartisan Financing Our Futures Act, which expands certain financing tools to all types of energy resources and infrastructure projects, was reintroduced to the U.S. Senate on February 20 by Sens. Jerry Moran (R., Kan.) and Chris Coons (D., Del.).
Via amendment to the Internal Revenue Code, the legislation would allow advanced nuclear energy projects to form as master limited partnerships (MLPs), a tax structure currently available only to traditional energy projects.
An MLP is a business structure that is taxed as a partnership but the ownership interests of which are traded like corporate stock on a market. Until the Internal Revenue Code is amended, MLPs will continue to be available only to investors in energy portfolios for oil, natural gas, coal extraction, and pipeline projects that derive at least 90 percent of their income from these sources. This change would take effect on January 1, 2026.

Irradiation-induced swelling in 20% cold-worked Type 316 stainless steel can be described by the use of a bilinear equation with three governing parameters. These parameters are R, a steady-state or linear swelling rate, τ, an incubation parameter denoting a fluence beyond which the linear, or high swelling, portion of the curve is attained, and a, a curvature parameter designating the degree of sharpness by which the equation curves from a region of low swelling to a region of higher swelling. This equation is intended for inclusion in the Nuclear Systems Materials Handbook and was developed with data extending to fluences around 16 × 1022 n/cm2(E> 0.1 MeV). The data set utilized includes first core Fast Flux Test Facility (FFTF) cladding specimens and specimens from several non-FFTF lots of cladding, in addition to supplemental data from an air-melted heat of steel. Heat-to-heat variations in swelling are significant in this material, and separate incubation parameters were developed for different lots of cladding.
