Ho Nieh nominated to the NRC
Nieh
President Trump recently nominated Ho Nieh for the role of commissioner in the Nuclear Regulatory Commission through the remainder of a term that will expire June 30, 2029.
Nieh has been the vice president of regulatory affairs at Southern Nuclear since 2021, though he is currently working as a loaned executive at the Institute of Nuclear Power Operations, where he has been for more than a year.
Nieh’s experience: Nieh started his career at the Knolls Atomic Power Laboratory, where he worked primarily as a nuclear plant engineer and contributed as a civilian instructor in the U.S. Navy’s Nuclear Power Program.
From there, he joined the NRC in 1997 as a project engineer. In more than 19 years of service at the organization, he served in a variety of key leadership roles, including division director of Reactor Projects, division director of Inspection and Regional Support, and director of the Office of Nuclear Reactor Regulation.

The radiative capture of unidirectional neutrons by the individual components of a stack of cadmium-covered gold foils was investigated for several spectra, principally those obtained by various modifications of the emission from a 252Cf source. The relative experimental activation of the foils was empirically described by a simple three-group relation reflecting capture in the 5-eV resonance, the 60-eV resonance, and an “average” of other capture regions. The incident fluxes in these respective regions could then be identified, and it was shown that the relative activations of the individual foils due to neutrons in these three energy regions depended on the incident spectrum. The energy dependence of the flux in the 5- to 60-eV range was also empirically shown to depend on the neutron spectrum.
