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.

Former Exelon CEO Chris Crane remembered for “transformational milestones”
Crane
Exelon announced that Chris Crane, the company’s former chief executive, passed away on Saturday in Chicago at the age of 65.
Crane served as the company’s president and CEO from 2012 until his retirement in December 2022. During his tenure, he steered the energy company through several transformational milestones, including the successful mergers with Constellation Energy in 2012 and Pepco Holdings in 2016, creating the largest utility business by customer count in the United States.
In 2022, with the spin-off of Constellation as the generation and retail side of energy business (with the largest U.S. nuclear fleet), Crane led the creation of a stand-alone transmission and delivery energy company.

An engineering-scale pyroprocessing integrated efficiency test was conducted with sodium-bonded, spent Experimental Breeder Reactor II drive fuel elements. The major pieces of equipment used to conduct the test were the element chopper, Mk-IV electrorefiner, cathode processor, and casting furnace. Four batches of the spent fuel (containing 50.4-kg heavy metal) were processed under a set of fixed operating parameters. The primary goal of the test was to demonstrate the actinide dissolution and recovery efficiencies typical of the fixed operating parameters that have been developed for this equipment based on over a decade's worth of processing experience. The total mass balance for the test was 101.28% (slightly more output than input). The uranium mass balance for the test was 100.13%. The test results indicate that 99.3 wt% of uranium in the feed was electrochemically dissolved and 98.4 wt% of the uranium was collected as metal ingots. The complexity of zirconium behavior during electrorefining was confirmed by the test results. More than 85 wt% of the zirconium was electrochemically dissolved during the later stages of the electrorefining process. However, only 33.7 wt% of the zirconium was collected as metal in the ingots. The balance of the zirconium is believed to reside in the cadmium pool. The test also identified that the dross streams from the cathode processor and casting furnace account for ~2.4 wt% of the uranium relative to the feed.
