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.

Chapter 10. Ion Cyclotron Range of Frequency Heating | Special Issue on Large Helical Device (LHD) | doi.org/10.13182/FST10-A10838

Various ion cyclotron range of frequencies (ICRF) heating experiments have been conducted in the Large Helical Device (LHD) by changing the magnetic field strength and the wave frequency using hydrogen and helium. When the resonance layer of hydrogen was located in the peripheral region on the lower-magnetic field side, efficient electron heating, i.e., mode conversion heating, was realized. When the ion cyclotron resonance layer was located near the "saddle point" of magnetic field strength, where the gradient of the magnetic field strength is zero, hydrogen ions were efficiently heated by the minority ion heating. The second-harmonic ion cyclotron heating experiments were also conducted by decreasing the magnetic field strength, and the plasma was successfully sustained for 1 s. Ion tails were observed in the ion heating modes. High-energy ions were well confined by the inward-shifted magnetic configuration. The ion tail formed by the second-harmonic heating was enhanced by the injection of a perpendicular neutral beam.
