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.

New laws offer nuclear industry incentives for existing power plant uprates
This year, the U.S. nuclear industry received a much-needed economic boost that could help preserve operating nuclear power plants and incentivize upgrades that extend their lifespan and power output.
Signed into law in 2022, the Inflation Reduction Act offers production tax credits (PTCs) for existing nuclear power plants and either PTCs or investment tax credits (ITCs) for new carbon-free generation. These credits could make power uprates—increasing the maximum power level at which a commercial plant may operate—a much more appealing option for utilities.

Cesium (<5 × 10-3M) can be extracted from aqueous sodium iodide solutions into equal volumes of 0.2M I2 in nitrobenzene at 25°C with extraction coefficients as great as two thousand. Cesium may be back-extracted by equilibration with ∼4M or stronger nitric acid. The separation factor of cesium (∼10-7M) from sodium in extractions made from sodium iodide solutions into equal volumes of 0.2M I2 in nitrobenzene at 25°C remained fairly constant at ∼1500 up to ∼1M NaI. It decreased to ∼100 at 8M NaI. At this point the cesium extraction coefficient was still greater than two. The decrease in the separation factor is seen as largely due to the decrease in the ratio of the activity coefficient of the cesium ion to that of the sodium ion in the aqueous phase. Extraction data for sodium and cesium from various solutions and under a variety of conditions are given. Sodium and cesium ions are seen extracted as ion association compounds with triiodide ions. Polyiodide ions as complex as the enneaiodide are formed subsequently in the organic phase. Sodium and cesium polyiodides are thought to be essentially ionized in nitrobenzene. Extractions are believed to be the result of the “squeezing out” from aqueous solution into nitrobenzene of ion pairs of cations of small ionic potential together with large anions that are compatible with the organic solvent. The driving force behind the extractions comes largely from the reformation of the hydrogen bonded water structure in the relatively large cavities left by the extracted ion pairs.
