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
Isotopes & Radiation
Members are devoted to applying nuclear science and engineering technologies involving isotopes, radiation applications, and associated equipment in scientific research, development, and industrial processes. Their interests lie primarily in education, industrial uses, biology, medicine, and health physics. Division committees include Analytical Applications of Isotopes and Radiation, Biology and Medicine, Radiation Applications, Radiation Sources and Detection, and Thermal Power Sources.

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.

The effect of surface condition on the initiation of iodine-induced stress corrosion cracks in Zircaloy tubing was investigated. The internal surface of the Zircaloy tubing was given one of three surface treatments, namely etching, grit blasting, or shot blasting. Each of these treatments can readily be performed commercially on Zircaloy fuel cladding. Specimens of surface-treated tubing were locally stressed in an iodine environment at 590 K by indenting the outer surface of the tube wall with a small steel ball. The crack initiation pattern on the inner surface was examined in a scanning electron microscope. Crack initiation was found to be least developed for etched surfaces, was most developed for shot-blasted surfaces, and was developed to an intermediate degree for grit-blasted surfaces. Apparent anomalies between these crack initiation data and the time to failure data obtained previously in tube pressurization tests are rationalized on the basis of the cracking processes.
