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 method of forming one-dimensional networks that are equivalent to two-dimensional wave propagations with fluid-structure interactions was developed. The method was verified by analysis of the simple shaker for a computational experiment by the use of the MULTIPLEX code for one-dimensional hydraulics with fluid-structure interactions. By applying the method of network formation, the Fritz-Kiss experiment was subsequently analyzed. In the latter case, the computed in-water frequency was 17.39 Hz, in good agreement with the measured value, 17.0 Hz. Thus, the MULTIPLEX code was verified for analyses of two-dimensional systems with application of the network model.
