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.

Investigation of reactions between neptunium and soil samples representative of the saline area around the Gorleben salt dome (Federal Republic of Germany) was conducted to obtain an understanding of the transport mechanism of neptunium in saturated brine aquifers. Leaching of 237Np-doped glasses with brine under oxic conditions resulted in the release of soluble species of Np(V). Adsorption parameters obtained from the application of nonlinear sorption isotherms to static experiments were used to interpret the migration of neptunium through soil columns. The existence of two different adsorption sites reacting with neptunium at different rates was postulated. Retardation factors under oxic and anoxic conditions were measured. In anoxic environments such as those found in undisturbed repository horizons, more neptunium activity was fixed by the soil.
