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.

With the United States rethinking its strategy for the management and disposal of defense high-level radioactive waste and civilian used nuclear fuel (UNF), it is an opportune time to evaluate the near-term and long-term options and requirements for the U.S. geologic repository program. In this paper, we outline a research program investigating the behavior of salt when subjected to thermal loads like those that would be present in a high-level-waste (HLW) repository. This program builds upon the knowledge base developed as a result of previous repository program efforts and the successful licensing and operation of the Waste Isolation Pilot Project Transuranic waste repository. We present a preliminary evaluation of a conceptual repository design that, in principle, exploits the positive attributes of salt as a disposal medium while balancing heat management issues against other considerations such as efficiency of disposal operations and cost. The coupled thermal-mechanical behavior of the intact and crushed salt, which influences and is influenced by the liberation and movement of water present in the salt and hydrous minerals, will ultimately control the thermal and hydrochemical conditions in the repository and at the waste package. To address key scientific issues, we advocate a combination of laboratory-scale investigations, a thermal test in the field for a configuration that replicates a small portion of our conceptual repository design, and numerical simulations conducted to develop a validated model that can be used for future repository design or performance assessment purposes. Accompanying this testing program would be a broader set of investigations that we advocate be conducted in the context of an iterative and adaptive process for systematically reducing uncertainties as we build a science-based safety case for HLW disposal in salt.
