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 investigate the ability of light extinction spectrometry (LES) to characterize, at long distances, the size distribution and concentration of dust mobilized by laser cleaning methods (ITER wall detritiation and characterization of deposition layers) or by experiments dealing with a loss-of-vacuum accident. Potentially harmful effects induced by wall proximity, plasma plume broadband emission, and associated shock waves are shown to have a negligible influence on LES measurements, which demonstrates the interest in this optical technique for the aforementioned studies. However, our experimental results, based on aerosols of silica and tungsten powder aggregates, show that the present setup allows the characterization of dust volume fractions of less than [approximately equal]1-10 ppb for a probing length of 1 m (or by extrapolation [approximately equal]0.1-1 ppb for a probing length of 10 m).
