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.

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.

We have evaluated the energetics of the proton-11boron advanced fuel fusion cycle and find that the enhancement of reactivity obtained from non-thermal mechanisms is significantly less than the enhancement required for ignition or high gain operation. Based on a detailed calculation of synchrotron radiation losses, at least 135% enhancement of the reactivity is needed for ignition. The direct and induced radioactivity associated with the cycle, while being orders of magnitude lower than that of D-T, is not negligible and requires serious attention in the design. Thus, we conclude that, using our present physics knowledge, the p-11B cycle is not viable for commercial fusion power.
