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.

This work is focused on coupling PLanUNC (PLUNC), a set of software tools for radiotherapy treatment planning (RTP), with MCNP5 Monte Carlo N-Particle transport code, utilizing the RANDO phantom as the patient model and the Elekta Precise linac as the irradiation source for comparison. Thus, the main goal of this paper is to compare the results obtained from the default calculations of the treatment plan software with those obtained via the implementation of MCNP5 calculations. Monte Carlo techniques have been proved to be a more accurate dose calculation aid than conventional treatment planning systems, having the only limitation of computer time. The implementation of MCNP5 calculations in a commercial RTP software aims to provide more accurate dose mapping of the patient in reasonable computer times. The results obtained in this paper represent a significant contribution in the development of RTP patient dose simulations.
