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
Nuclear Criticality Safety
NCSD provides communication among nuclear criticality safety professionals through the development of standards, the evolution of training methods and materials, the presentation of technical data and procedures, and the creation of specialty publications. In these ways, the division furthers the exchange of technical information on nuclear criticality safety with the ultimate goal of promoting the safe handling of fissionable materials outside reactors.

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 study evaluates the mechanical strength, failure mechanism and change in electrical resistance under shear stress of a mechanical lap joint of Rare-Earth Barium Copper Oxide high-temperature superconducting (HTS) tapes using indium as bonding material, which has been proposed for “remountable” (demountable) or segmented HTS magnet in future fusion reactors. Results from tensile shear tests using reinforced REBCO tapes along with an analysis on the failure mode demonstrated that contact conductivity is the critical parameter that defines joint’s shear strength rather than joint pressure. Additionally, it was concluded that change in joint resistance when failure occur is not abrupt and its behavior as joint displaces depends on the failure mode of the joint.
