Division Spotlight
Reactor Physics
The division's objectives are to promote the advancement of knowledge and understanding of the fundamental physical phenomena characterizing nuclear reactors and other nuclear systems. The division encourages research and disseminates information through meetings and publications. Areas of technical interest include nuclear data, particle interactions and transport, reactor and nuclear systems analysis, methods, design, validation and operating experience and standards. The Wigner Award heads the awards program.

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.

A tubular-type fuel assembly has been considered as one of the candidates for the fuel of the Advanced HANARO Reactor (AHR). The hydraulic characteristics of the tubular fuel under consideration have been investigated by an experiment and a computational fluid dynamics (CFD) analysis. To measure the flow distribution and the pressure drop, a test facility was constructed, and a mock-up of a tubular fuel was fabricated. A pitot tube was employed to measure the coolant velocity in the flow channels. Numerical analysis by the CFD code was also conducted to compare its results with the test results and to obtain insight into the flow structure in a tubular fuel. The simulation results by the CFD analysis showed reasonable agreement with the measurements for the flow distribution as well as good agreement for the pressure drop in a tubular fuel.
