Senate EPW Committee to hold Nieh nomination hearing
Nieh
The Senate Environment and Public Works Committee will hold a nomination hearing Wednesday for Ho Nieh, President Donald Trump’s nominee to serve as commission at the Nuclear Regulatory Commission.
Trump nominated Nieh on July 30 to serve as NRC commissioner the remainder of a term that will expire June 30, 2029, as Nuclear NewsWire previously reported.
Nieh has been vice president of regulatory affairs at Southern Nuclear since 2021, though since June 2024 he has been at the Institute of Nuclear Power Operations as a loaned executive.
A return to the NRC: If confirmed by the Senate, Nieh would be returning to the NRC after three previous stints totaling nearly 20 years.

This paper discusses the physical and mathematical foundations and possible applications of the intensity correlation method for spatial three-dimensional (3-D) positional detection (finding the 3-D spatial position) of distant γ-ray or neutrino sources in real time or after a set of registered events. This method is based on the correlation of intensities of event sequences measured by several spaced-apart distant detectors. A specific consideration is made of the possibility of using a correlation intensities method for the analysis of the processes within a nuclear reactor, for the search of the hypothetical intra-terrestrial georeactor (planetocentric nuclear fission reactors), for the optimization of the method of single-photon-emission-computed tomography in medicine, and for other applications. The conditions of successful applications of the intensity correlation method for these systems are determined. The main problem with this method is connected to a relatively low count rate of registered neutrino events.
