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.

The main reasons for conducting research and development (R&D) on an advanced pressurized water reactor (APWR) with a high conversion ratio include an awareness of the limited availability of natural nuclear fuels, the low degree of utilization of this resource in present light water reactors (L WRs), and the necessary high capital investments in breeder reactor systems with high fuel utilization. Consequently, these R&D efforts, on the one hand, must greatly increase the utilization of uranium compared to the level achieved in L WR technology and, on the other hand, must reduce the capital investment compared to what is required in breeder reactor technology. If these criteria can be met economically, a future role would be indicated for APWRs as an interim technology during the transition from LWRs to breeder reactors and as a supplement to the latter line in a breeder/APWR symbiosis. It appears that an APWR will use nuclear resources economically but will also create higher costs for an electric utility than current LWR technology.
