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.

The flute instabilities were investigated in the GAMMA10 A-divertor magnetic field with help of computer simulations. The basic equations used in the simulation can be applied to only an axisymmetric system. So the high pressure in the remaining non-axisymmetric anchor cell, which is used for the flute mode stability, is taken into account by redefining the specific volume of a magnetic field line. It is found that the minimum-B mirror can stabilize a flute mode even in a divertor mirror cell, but its stabilizing effects are weaker. The radial transport accompanied by the flute instabilities in the GAMMA10 A-divertor is found to be rather smaller than that without a divertor mirror cell.
