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.

Fusion fuel processing systems are expected to rely on multi-column, cryogenic distillation systems for separating hydrogen isotopes. These systems will run continuously and need to respond to feeds varying considerably in both composition and flowrate. These systems will also need to operate with minimal inventories due to the value and safety concerns associated with tritium. These factors result in a clear need for a system of automatic control to maintain the isotope separation system operating properly. Such a system of regulatory (or material balance) controls have been added to the four-column ISS at the Tritium Systems Test Assembly. These controls have been tuned and tested individually. Then the overall system was demonstrated to work successfully. The results of this work is reported in this paper.
