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
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.

The Tritium Storage & Delivery System (SDS) is part of a tokamak-type nuclear fusion reactor fuel cycle. For the safety of this cycle, the hydrogen isotopes are stored in a metal hydride form in the SDS. Depleted uranium (DU) was chosen as the storage material. DU hydride can be heated to very high temperatures that are sufficient for pumping hydrogen isotopes without using gas pumps. The experimental apparatus used to test the experimental DU bed consists of a tank that stores and measures the hydrogen, and a DU bed used for the hydriding and dehydriding of hydrogen. The DU bed is a vertical double-cylinder type with sintered metal filters. The bed is composed of primary and secondary vessels. The primary vessel contains DU, and a vacuum layer is formed between the primary and secondary vessels. In this study, recent experimental results on the pretreatment (activation and powderization) of DU and the direct hydrogen recovery and delivery of a DU bed are presented. In addition, the relationship between hydrogen pressure and temperature in the DU bed is obtained.
