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.

A nonelectrolytic method for uranous preparation, deploying catalytic reduction with hydrogen and leading to highly improved kinetics and near total conversion of uranyl nitrate to uranous nitrate, has been developed. Detailed experimental studies up to 5-ℓ scale, involving selection of stable supports for the platinum-based catalyst, optimized process parameters with regard to catalyst-to-uranium (C/U) ratio, acidity, hydrazine concentration, temperature, and pressures, have led to a deployable flow sheet, for near total conversion of uranyl nitrate to uranous nitrate.
Based on the studies at various stages, a facility for making 70 ℓ of uranous per batch in 0.5-h duration has been installed, and the process has been demonstrated on a pilot scale. Active runs have been taken, with various C/U ratios, namely, 1:200, 1:250, 1:300, and 1:350, in a gas induction reactor with uranyl nitrate solution generated from the reprocessing plant.
