ANS is committed to advancing, fostering, and promoting the development and application of nuclear sciences and technologies to benefit society.
Explore the many uses for nuclear science and its impact on energy, the environment, healthcare, food, and more.
Division Spotlight
Isotopes & Radiation
Members are devoted to applying nuclear science and engineering technologies involving isotopes, radiation applications, and associated equipment in scientific research, development, and industrial processes. Their interests lie primarily in education, industrial uses, biology, medicine, and health physics. Division committees include Analytical Applications of Isotopes and Radiation, Biology and Medicine, Radiation Applications, Radiation Sources and Detection, and Thermal Power Sources.

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 large, vertical shock tube is used to explore the breakup and mitigation effects of liquid layers expected from the hydrodynamic shock generated in an inertial fusion reaction. Single and multiple layers of water are tested at two Mach numbers, 2.12 and 3.20. X-ray radiography techniques are used to image the breakup of the water layer resulting in a quantitative measure of the mass fraction distribution of water after shock impact. The amount of breakup is increased with the addition of multiple layers and the increased breakup decreases the end wall impulse. The speed of the transmitted shock wave can be reduced by 50% and is a weak function of the number of layers. The peak pressure at the end-wall of the shock tube is significantly increased due to the high impulsive force of the single liquid layer, however this pressure is substantially reduced when multiple layers containing the same mass of water are used.
