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
Decommissioning & Environmental Sciences
The mission of the Decommissioning and Environmental Sciences (DES) Division is to promote the development and use of those skills and technologies associated with the use of nuclear energy and the optimal management and stewardship of the environment, sustainable development, decommissioning, remediation, reutilization, and long-term surveillance and maintenance of nuclear-related installations, and sites. The target audience for this effort is the membership of the Division, the Society, and the public at large.

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 investigation of iodine absorption on ion exchange resins in aqueous electrolyte solutions has been performed. For I- and I ions, the distribution coefficients are inversely proportional to the electrolyte concentration in solutions, whereas the adsorption of HIO with ion exchange resins is independent of electrolyte concentration in solutions. The mechanism of HIO adsorption is believed to be surface matrix adsorption rather than the ion exchange process. The distribution coefficients for HIO measured at both 20 and 56°C are nearly constant, whereas the coefficients for I- and I ions are approximately a factor of 100 smaller at the higher temperature. The distribution coefficients for I- ions in water are generally on the order of 104, which is approximately three to five times larger than that for I- ions. The half-time of the exchange reaction for I ions with the strong acid resin in water at 20°C is ∼50 s, compared to ∼90 s for I ions. Some experimental data obtained in an operating boiling water reactor have also been reported.
