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.

Zero-variance Monte Carlo schemes have been discussed in the literature at several places. Taking a fresh look, it turns out that some authors made essential errors in their derivation and conclusions. We will prove that for a given estimator there is only one zero-variance scheme possible with a unique biasing of the source function and the transition and collision kernels. A practical demonstration of a zero-variance scheme will be shown numerically for a two-group homogeneous slab system treated by the two-direction transport model, which provides an analytical solution for the particle flux and adjoint functions.
