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 fuel cycle (FC) model FC-FNS is used for the calculation of hydrogen isotope flows in the fuel systems of the DEMO-FNS fusion neutron source (FNS) based on a tokamak with parameters R/a = 3.2 m/1 m, B = 5 T, Ipl = 4 to 5 MA, PNBI = 30 MW, РECR = 6 MW, and deuterium-tritium fusion power Pf = 40 MW. The FC-FNS model includes joint simulation of the gas, solid-state, and plasma flows of the fuel mixtures in the areas of the core and near-wall plasma when neon admixture is injected into the divertors. The basic principles of particle balance formation in the plasma and FC systems are described in the paper. In the process of fueling mode optimization, the requirements for productivity of the key FC systems containing the largest amount of T have been formulated. The FC configuration with the minimum tritium reserve (<2 kg) and the shortest processing time is selected.
