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 separation properties of the hydrocyclone and the centrifuge were compared with regard to applying the apparatus in the uranium extraction process. The product was applied as a comparative factor where is the average emulsion residence time inside the separator and ā is the acceleration calculated for the mean radius of the separator chamber. The values corresponding to typical operational conditions of centrifuges tested appeared to be significantly higher than those calculated for the hydrocyclone. Separation tests performed with the 1 N HNO3-30% tributyl phos-phate-Mepasine system gave negative results in the case of the hydrocyclone while the complete emulsion separation was attained in various centrifuges under conditions when 9 × 105 cm·s−1. The results obtained suggest that the ≥ product can be applied as the criterion of the satisfactory phase separation in the centrifugal apparatus.
