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.

Membrane detritiation processes using gas permeation membrane have the advantages of being simple in system configuration and compact in size compared to conventional oxidation followed by adsorption process. The experiment was performed using a gas separation module made of a polyimide membrane with dry nitrogen gas containing small amount of hydrogen gas and moisture, and an analytical study was performed to establish the theoretical treatments of the membrane separation of hydrogen, water from nitrogen. The experimental and analytical study revealed that the membrane separation process has a high selectivity for hydrogen and water from nitrogen, especially separation performance for water is very high. The effect of operation parameters on the separation performance can be predicted, and the design of the detritiation system of a fusion reactor facility can be constructed based on the present study.
