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.

Total hemispherical emissivity of Alloy 617 was measured for applications in very high temperature reactors with apparatus based on ASTM Standard C835-06. The emissivity data were obtained for the following surface conditions: (1) as-received (rolled sheets) from manufacture, (2) sandblasted with aluminum oxide beads, (3) oxidation in air at temperature of 1153 K, and (4) coated with graphite powder. For the as-received Alloy 617, emissivity increased from 0.26 to 0.34 over the temperatures 593 K to 1164 K. Sandblasting Alloy 617 with alumina beads increased the emissivity to 0.46 to 0.73 in the temperature range 600 to 1300 K (emissivity increased further when higher grit size beads were used). The oxidation of Alloy 617 gave a slight increase in emissivity from 900 to 1250 K with larger increases above 1100 K. Coating of graphite onto as-received and 60-grit sandblasted increased the emissivity by roughly 0.12 and 0.20, respectively, over the measured temperature range.
