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
Accelerator Applications
The division was organized to promote the advancement of knowledge of the use of particle accelerator technologies for nuclear and other applications. It focuses on production of neutrons and other particles, utilization of these particles for scientific or industrial purposes, such as the production or destruction of radionuclides significant to energy, medicine, defense or other endeavors, as well as imaging and diagnostics.

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.

An experimental study of the downward penetration of molten UO2 into substrate limestone concrete was conducted. Joule heating was used to melt the UO2. The technique allowed for sustaining of the molten phase for a long time period. The released gases from concrete eliminated the sintering of UO2 and caused the formation of single large interior cavity in the UO2/concrete solidified mixture. Uplifting of the top surface of the mixture and the formation of a mountain-like protrusion, bearing a vent hole on its apex, resulted from significant internal pressure. Except for the bottom surface of the solidified mixture, which was continuous and glassy-like, all the other surfaces were porous. Analyses of selected samples revealed the presence of calcium uranate type compounds. Concrete constituents were well distributed throughout UO2. Magnesium did not participate in compound formation with UO2. Finally, dissolution of the concrete constituents in UO2 resulted in reduction of the internal-heat generation.
