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.

Garrish up for repeat term as DOE’s nuclear energy secretary
Garrish
Theodore “Ted” Garrish—who has spent more than four decades working in nuclear—is President Donald Trump’s nominee to serve as the Department of Energy’s assistant secretary for nuclear energy, or, NE-1.
The nomination was referred to the U.S. Senate’s Committee on Energy and Natural Resources on February 3. Garrish previously held the office from 1987 to 1989 under President Ronald Reagan. Most recently, Kathryn Huff held the NE-1 post, and Michael Goff has served as interim assistant secretary since Huff stepped down in May 2024.
Garrish’s most recent term in public office was as assistant secretary for the Office of International Affairs at the Energy Department, from 2018 to 2021, during Trump’s first term. Supporters say Garrish’s 40-plus years working in the nuclear industry and in nuclear energy oversight positions makes him more than qualified to serve in the DOE office again.

We have created a forward model for charge-exchange impurity density measurements that incorporates neutral beam attenuation measurements self-consistently for the purpose of determining the ion-effective charge Zeff. The model is constructed within an integrated data analysis framework to include a self-consistent calculation of neutral beam attenuation due to multiple impurity species into the measurement of a single impurity density. The model includes measurements of the beam Doppler-shift spectrum and shine-through particle flux to determine the neutral beam particle density which is attenuated by ion collisions. Synthetic data are generated from the diagnostic forward model using statistical and calibration uncertainties. These “noisy” data are used in the analysis to evaluate how accurately Zeff is determined. Methods of experimental design are employed to calculate the information gained from different diagnostic combinations. The analysis shows that while attenuation measurements alone do not provide a unique impurity density measurement in the case of a multispecies inhomogeneous plasma, they do provide an effective measurement of the Zeff profile and place constraints on the impurity density profiles.
