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.

A hot-dip process developed in FZK, was applied to produce a hydrogen permeation barrier on MANET steel. The formation of the alumina layer is a two step process. The hot-dip aluminizing method produced first an intermetallic layer of FexAly by immersing the specimens in molten aluminium at 1073 K for 10 min. Secondly, by its exposure to an oxygen containing gas (1223 K, 10 and 30 h) the alumina layer is formed on the intermetallic layer. The last step is to form a fully martensitic phase (δ-ferritic free structure) by a specific heat treatment (1348 K, 30 min fast cool; 1023 K, 2 h).The oxide layer and bulk material were characterized by optical metallography, Vickers microhardness measurements, scanning electron microscope (SEM) with energy dispersive X-ray analysis (EDX), X-ray photoelectron spectroscopy (XPS), and X-ray diffraction (XRD) on the surface. A permeation reduction larger than three orders of magnitude was obtained in the sample that has undergone a 30 h exposure in air at 1223 K.
