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.

Thermal plutonium recycling has been demonstrated by Kraftwerk Union AG/Alkem on a large scale since 1972 in power plants at Obrigheim and Gundremmingen, Federal Republic of Germany (FRG). An improved mixed-oxide (MOX) fuel fabrication technology has been available since 1981. Such improved MOX fuel is currently being used at Obrigheim, Neckarwestheim, Unterweser, Grafenrheinfeld, FRG, and Beznau 2, Switzerland. The MOX fuel assemblies currently inserted exhibit an operating performance that is comparable to that of uranium fuel assemblies. Postirradiation investigations on MOX fuel show high mechanical stability, low shrinkage and swelling, and good behavior during power transients. On the basis of this experience, large-scale use of MOX fuel is technically feasible.
