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.

Millimeter-scale shock tubes with precision-machined submillimeter features have been developed for hydrodynamic instability experiments conducted on the Nova laser facility. We will describe two specific designs: a silica aerogel tracer disk and an aluminum-doped epoxy tracer strip, both embedded in the shock-tube target. These unique features facilitate radiographic imaging of key phenomena of interest. We describe in detail the construction and characterization of the miniature targets, including the fabrication and emplacement of the radiographic tracers. A sample of the experimental data is presented.
