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.

Magnetic flux surface measurements have been carried out in the Large Helical Device (LHD) in the standard magnetic field configuration with toroidal magnetic field strength up to 2.75 T. An electron beam launched with a small electron gun moving across the flux surfaces was detected with a fluorescent screen or a probe array. Nested surfaces could clearly be visualized with both methods. Even the stochastic region was detected. In the experiment, unfavorable m/n = 1/1 and 2/1 magnetic islands were discovered near the last closed flux surface, where m and n are poloidal and toroidal mode numbers, respectively. There is a possibility that the source of the error field, in the low magnetic field of 0.0875 T, is terrestrial magnetism. On the other hand, in the standard magnetic field of 2.75 T, the main source of the error field is thought to be ferromagnetic materials near the torus of LHD. Fortunately, it was demonstrated that such magnetic islands can be reduced or eliminated by applying a correction field with some perturbation coils.
