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
Fusion Energy
This division promotes the development and timely introduction of fusion energy as a sustainable energy source with favorable economic, environmental, and safety attributes. The division cooperates with other organizations on common issues of multidisciplinary fusion science and technology, conducts professional meetings, and disseminates technical information in support of these goals. Members focus on the assessment and resolution of critical developmental issues for practical fusion energy applications.

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 reduction in projected sodium outlet temperatures for commercial liquid-metal fast breeder reactors has renewed the interest in metal fuels. The U-Pu-Zr or Th-Pu-U-Zr metal fuel pins, sodium bonded to stainless-steel claddings, will yield high burnup along with adequate fuel-cladding compatibility. High burnup capability is assured by designing the fuel element so that interconnected porosity and flssion-gas release occur prior to fuel-cladding contact. Interconnected porosity and fission-gas release take place at about 30% fuel-volume swelling, independent of the metal fuel composition. The U-Fs/Type 316 stainless-steel-clad driver-fuel element used in the Argonne National Laboratory Experimental Breeder Reactor II is designed to take advantage of the phenomenon of interconnected porosity, and burnups in excess of 10 at.% are typically achieved prior to cladding breach. The adequate fuel-cladding compatibility, high burnup potential, superior breeding performance, and demonstrated remote refabrication have made metal fuels an attractive alternative for fast reactor design.
