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
Reactor Physics
The division's objectives are to promote the advancement of knowledge and understanding of the fundamental physical phenomena characterizing nuclear reactors and other nuclear systems. The division encourages research and disseminates information through meetings and publications. Areas of technical interest include nuclear data, particle interactions and transport, reactor and nuclear systems analysis, methods, design, validation and operating experience and standards. The Wigner Award heads the awards program.
Meeting Spotlight
ANS Student Conference 2025
April 3–5, 2025
Albuquerque, NM|The University of New Mexico
Standards Program
The Standards Committee is responsible for the development and maintenance of voluntary consensus standards that address the design, analysis, and operation of components, systems, and facilities related to the application of nuclear science and technology.

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.

A ternary 15 Cr—35 Ni—50 Fe alloy and three versions of the same base doped with niobium, titanium, or molybdenum were exposed in the temperature range from 700 to 1000°C to simulated high temperature reactor helium in two corrosion experiments that differed mainly in moisture content at the High Temperature Materials Programme in Wimborne, United Kingdom. The water level in Run B was about ten times higher than in the dryer Run A. As expected, oxides that formed during exposure in the oxidizing atmosphere of Run B were generally thicker. Thickness and structural appearance of the oxides varied between the four alloys in both runs. In electron probe microanalysis studies the oxides were found to be virtually pure chromium oxides containing no significant amounts of the additives. It is inferred that variations in thickness and structural appearance of the oxides are caused by differences in kinetics of chromium oxidation, depending on the additives.
